mdds 2.0.3
* general
* defined clang-format rules, and globally applied them to all active
source files.
* multi_type_vector
* revised the block position lookup implementation to avoid using the
internal STL iterators. The new implementation should be able to handle
invalid position hints more gracefully without potential process
termination.
mdds 2.0.2
* multi_type_vector
* added optional trace function that gets called on every called public
method.
mdds 2.0.1
* general
* addressed various coverity issues.
* multi_type_vector
* fixed random compiler warnings.
* fixed event handling in copy construction. In aos, the event object was
not copied when the parent container was copied. In soa, the
element_block_acquired() callback was not called for the cloned element
blocks.
* added move constructors and move assignment operators to both aos and soa
variants.
mdds 2.0.0
* general
* set the baseline C++ version to C++17.
* multi_type_vector
* implemented structure-of-arrays (SoA) storage as its default storage
layout for better CPU cache efficiency.
* added multiple block position adjustment implementations with various
loop-unrolling factors combined with SSE2 and AVX2 features.
* added a tool called runtime-env to benchmark different block position
adjustment implementations to determine the optimal loop-unrolling factor.
* rectangle_set
* permanently removed.
* rtree
* fixed a bug where the memory positions of invalidated child nodes were not
properly updated after tree mutation. The problem manifested itself when
using libc++ as stdlib with clang.
mdds 1.7.0
* trie_map
* added copy and move constructors.
* added a variant of find() method that returns a mutable iterator object.
The user can now update the value associated with a key directly via the
iterator object.
* packed_trie_map
* added copy and move constructors.
* added load_state() and save_state() methods to allow loading state from
and saving state to binary files.
mdds 1.6.0
* multi_type_vector
* switched to using binary search on block position lookup, which
significantly improves element access performance in general, at the
expense of slight performance degradation on block shifting.
* added support for lcov, to visualize test coverage.
mdds 1.5.0
* documentation
* moved the documentation hosting to readthedocs.io, and adjusted the build
steps.
* moved the API incompatibility notes from README to the rst doc.
* added the overview section for flat_segment_tree.
* multi_type_vector
* fixed the static get(const const_position_type& pos) method for the
boolean_element_block, by adding specialization for it to work around the
issue with std::vector<bool> not having the at() method.
* fixed an issue with the const position() method not returning a valid end
position the same way the non-const variant does.
* added steps to traverse blocks backward from the postiion specified in the
position hint. This may result in improved performance in some
situations.
* the standard integer blocks now use fixed size integer types i.e.
* (u)int8_t
* (u)int16_t
* (u)int32_t
* (u)int64_t
* The numeric_element_block has been renamed to double_element_block.
* added new block type to store float element values.
* general
* added gdb pretty printers that prints the contents of the data structures.
mdds 1.4.3
* documentation
* added details on how to use two type of iterators with
flat_segment_tree.
* added new section to describe how to use mtv::collection to iterate
through multiple multi_type_vector instances as a single collection
in the direction orthogonal to the direction of the individual
vectors.
* added new page for R-tree.
* flat_segment_tree
* fixed invalid memory access issue related to the swap() method which
previously did not swap the non-leaf node pool store. The invalid
memory access may occur after the contents of two instances get
swapped, one instance get destroyed then the caller calls
search_tree() on the other instance still alive.
mdds 1.4.2
* all
* fixed CXXFLAGS incorrectly being overwritten.
* addressed a number of Coverity issues.
mdds 1.4.1
* all
* fixed all warnings on shadowed variables.
* multi_type_matrix
* all of its walk() methods now return either a copied or moved
instance of the function object passed in as an input argument.
Previously these methods had no return values.
mdds 1.4.0
* rtree (new)
* new data structure designed for optimal storage and query
performance on multi-dimensional spatial data. The structure allows
storage of both point and extent-based boundaries as keys associated
with values.
* multi_type_vector
* mtv::elemnt_block now has the following methods: data(), cbegin(),
cend(), crbegin() and crend().
* multi_type_vector now has cbegin(), cend(), crbegin(), and crend()
methods.
* some unnecessary user-provided special members have been removed to
avoid warnings with -Wdeprecated-copy with GCC 9.
* multi_type_matrix
* all of its walk() methods now allow in-line lambdas to be used, by
not taking a reference of the function object parameters.

* fixed a bug that caused an assertion error when inserting a
out-of-bound segment whose start value equals the max key value.
mdds 1.3.0
* multi_type_vector
* changed the primary block array storage to remove additional
indirection, for improved memory locality.
mdds 1.2.3
* all
* changed the configure script to use --docdir unmodified.
* flat_segment_tree
* added a segment iterator whose node value consists of the start
and end keys and the value associated with each segment. its
start and end positions can be retrieved via begin_segment() and
end_segment() methods.
mdds 1.2.2
* flat_segment_tree
* fixed a bug that would cause segmentation faults with the insert()
method with out-of-bound segment value pair.
mdds 1.2.1
* multi_type_vector
* added size() method to the element block type, which returns the
actual size of the element block, instead of the cached size value
stored in the parent structure that stores the element block.
* fixed a double-deletion bug in the swap() method which would
triggered when used with a managed element block.
* mtv::collection
* fixed collection iterator's get() method to properly return values
from the boolean element block.
mdds 1.2.0
* packed_trie_map
* added begin() and end() methods that return read-only iterators.
* find() method now returns a const_iterator instance.
* prefix_search() method now returns a search_results instance that
can be iterated.

* prefix_search() method now returns a search_results instance that
can be iterated.
* null value no longer needs to be passed to the constructor.
* find(), insert, and prefix_search() now have a variant that can
take a key value that is of key_type directly.
* sorted_string_map
* fix build failure with _GLIBCXX_DEBUG defined.
* multi_type_vector
* remove compiler warning about shadowed variable.
* added a supplemental class mdds::mtv::collection which allows
multiple multi_type_vector instances of the same length to be
grouped together in order to iterate through their elements
sideways.
* a variant of advance_position() static method that takes
const_position_type has been added.
* const_position_type advance_position(const const_position_type& pos, int steps)
* multi_type_matrix
* matrix_position() is now a const method.
* the sub-matrix variant of walk() method now throws size_error
exception when invalid start and end positions are passed.
* slight performance improvement with the sub-matrix variant of
walk() method that involves multiple column traversal.
* added 2 new variants of walk() methods that allow parallel walking
with another matrix instance.
* template<typename _Func>
void walk(_Func& func, const multi_type_matrix& right) const
* template<typename _Func>
void walk(_Func& func, const multi_type_matrix& right, const size_pair_type& start, const size_pair_type& end) const

* template<typename _T>
void copy(size_type rows, size_type cols, const _T& it_begin, const _T& it_end)
* integer type has been added to the list of types the matrix can
store. In conjunction with this change, what was formerly known
as the string trait structure is now known as the matrix trait,
which specifies the actual integer type the matrix stores.
* point_quad_tree
* search_result has been renamed to search_results.
mdds 1.1.0
* all
* switched our build system to using automake.
* packed_trie_map (new)
* new data structure that implements a trie also known as a prefix
tree. This implementation requires all key values be known at
construction time, after which its content is considered
immutable. Internally it packs all its nodes in a single
contiguous array for space and lookup efficiencies.
* trie_map (new)
* new data structure that implements a trie. It works similar to
packed_trie_map except that this version is mutable.
* multi_type_matrix
* added a variant of walk() that takes the upper-left and
lower-right corners to allow walking through a subset of the
original matrix.
* multi_type_vector
* fixed incorrect return values of the increment and decrement
operators of in-block iterators. They would previously return a
value_type pointer which did not conform to the behaviors of STL
iterators.
* added support for custom event handlers for element block
acquisitions and releases.
* flat_segment_tree
* fixed incorrect return values of the increment and decrement
operators of its leaf-node iterators as in multi_type_vector's
fix.
* sorted_string_map
* significantly improved the performance of its find() method by
switching from using linear search to using binary search. The
improvement is especially visible with a large number of elements.
mdds 1.0.0
* all
* introduced API versioning to ease parallel installation of API
incompatible versions. Version 1.0.0 will have an API versoin of
1.0.
* C++11 is now a hard requirement.
* added API documentation via Doxygen, Sphinx and Breathe.
* mixed_type_matrix
* officially removed for good in favor of multi_type_matrix.
* multi_type_vector
* added memory usage reduction by conditionally shrinking the
capacity of the underlying vector containers.
* added slight performance gain by revising block adjustment policy
during splitting of blocks.
* sorted_string_map
* fixed a bug where a non-matching key was incorrectly returned as a
matching key.
mdds 0.12.1
* flat_segment_tree
* removed construction-from-int requirement from value_type to allow
non-numeric types to be stored.
* multi_type_vector
* added static method advance_position() to allow incrementing or
decrementing the logical position of a position_type object:
* position_type advance_position(const position_type& pos, int steps)
mdds 0.12.0
* segment_tree
* removed pointer requirement from value_type to allow non-pointer
type to be stored.
* multi_type_vector

mdds 0.11.2
* multi_type_vector
* fixed various memory leaks associated with the set() method when a
value overwrites an existing element in a managed block.
mdds 0.11.1
* all
* fixed a large number of outstanding defects reported by Coverity
Scan.
* multi_type_vector
* fixed 2 cases of double-free bug in the variant of swap() that
allows segmented swapping.
mdds 0.11.0
* sorted_string_map (new)
* new data structure to support efficient mapping of textural keys
to numeric values when the key values are known at compile time.
* multi_type_vector
* fixed a bug in transfer() where two adjacent blocks of identical
type would fail to be merged in some circumstances.
* added shrink_to_fit() to allow trimming of any excess capacity
from all non-empty blocks.
* fixed a double-free bug in the variant of swap() that allows
segmented swapping.
* improved the exception message when the block position lookup
fails to find valid block position, to make it easier to debug.
mdds 0.10.3
* multi_type_vector
* added 2 variants of release_range() that take start and end positions,
to allow releasing of elements in specified interval. One of the
variants takes iterator as a block position hint.
* iterator release_range(size_type start_pos, size_type end_pos)
* iterator release_range(const iterator& pos_hint, size_type start_pos, size_type end_pos)
* added push_back() and push_back_empty(), to allow efficient way to
append new values to the end of the container.
* template<typename _T>
iterator push_back(const _T& value)
* iterator push_back_empty()
mdds 0.10.2
* multi_type_vector
* fixed a bug in transfer() that would trigger an assertion and
eventually lead to a crash. The problem occurred when a range of
data to be transferred spanned over 2 blocks and consisted of the
lower part of an upper block and the upper part of a lower block.
mdds 0.10.1
* multi_type_matrix
* added a variant of set_empty() that takes an additional length
parameter.
* void set_empty(size_type row, size_type col, size_type length)
mdds 0.10.0
* flat_segment_tree
* significant performance improvement on build_tree() and
search_tree(), by optimizing the non-leaf node object generation
and storage to achieve better locality of reference.
* segment_tree
* slight performance improvement on build_tree(), as a result of the
optimization done for flat_segment_tree since these two structures
share the same tree generation code.
* multi_type_vector
* improved debug message on mis-matched block types (only when
MDDS_MULTI_TYPE_VECTOR_DEBUG is defined).
mdds 0.9.1
* multi_type_vector
* added several convenience methods for position objects.
* performance improvement on setting array values.
* added new constructor that takes an array of values as initial
element values.
* multi_type_matrix
* setter methods that take a position object to also return a
position object.
* added several convenience methods for position objects.
* added new constructor that takes an array of values as initial
element values.
mdds 0.9.0
* multi_type_vector
* added another block function template to make it easier to declare
container with 3 custom element types.
* added two variants of release():
* template<typename _T> iterator
release(size_type pos, _T& value)
* template<typename _T> iterator
release(const iterator& pos_hint, size_type pos, _T& value)
* added a variant of release() that takes no arguments. This one
releases all elements and makes the container empty afterward.
* added a new variant of position() that takes const_iterator as
position hint.
* std::pair<const_iterator, size_type>
position(const const_iterator& pos_hint, size_type pos) const
* fixed a memory leak in
* set(size_type pos, const _T& it_begin, const _T& it_end).
* added compile-time macro MDDS_MULTI_TYPE_VECTOR_USE_DEQUE to allow
users to specify std::deque as the underlying data array. By
default, multi_type_vector uses std::vector as the underlying data
array container.
* added a new variant of swap() that allows partial swapping of
content with another container.
* added static block type identifier so that the numeric block type
ID can be deduced from the block type directly.
* value_type (which is a type of object returned when dereferencing
an iterator) now stores 'position' which is the logical position
of the first element of a block.
* added position_type and const_position_type which are typedefs to
the return types of position() methods.
* multi_type_matrix:
* get_numeric(), get_boolean(), and get_string() are made more
efficient.
* added position() method that returns a reference object to an
element (position object).
* added variants of get_numeric(), get_boolean() and get_string()
that retrieves elements from position objects.
* added variants of set() that sets new element values via position
objects.
mdds 0.8.1
* multi_type_vector
* fixed a bug in the erase() method where adjacent blocks of the
same type would fail to merge after the erase() call.
* add a variant of the position() method that takes an iterator as
positional hint. Note that there is no variant of position() that
takes const_iterator.
mdds 0.8.0
* all
* added .pc file for pkg-config.
* flat_segment_tree
* changed the return type of search_tree from bool to
std::pair<const_iterator,bool>, to make it consistent with the
search() method. Note that this is an API-incompatible change.
* multi_type_vector
* added char and unsigned char types to the standard types supported
by default.
* added position() member method that takes a logical element
position and returns a pair of block iterator where the element
resides and its offset within that block.
* added at() static member method to the data block, which calls the
at() method of the underlying std::vector container.
* added release() member method to allow caller to release an object
stored inside a managed block.
* added two templates to ease creation of custom element block
functions when using one or two custom element types.
* added transfer() member method to allow elements in a specified
range to be transferred from one container to another. When
transferring elements stored in a managed element block, the
ownership of those elements is also transferred.
mdds 0.7.1
* multi_type_vector
* fixed a bug in set_empty() where emptying a whole or partial block
would fail to merge its adjacent block(s) even when they are also
empty.
mdds 0.7.0
* multi_type_vector
* add variants of set() methods (both single- and multi-value)
insert(), set_empty() and insert_empty() methods that take an
iterator as an additional position hint parameter for block lookup
speed optimization.
* add support for non-const iterators which allow the client code to
modify values directly from the iterators.
* set() methods (both single- and multi-parameter variants),
set_empty(), insert() and insert_empty() methods now return
iterator that references the block to which the values are set or
inserted.
* fixed bugs in set() method (single-parameter variant) which would
insert a new block at incorrect position.
* fixed bugs in set() method (multi-parameter variant) which would
fail to merge neighboring blocks of identical type under certain
conditions.
mdds 0.6.1
* all
* use property files in the Visual Studio project files, to share
some of the common custom build variables across all projects.
* various build fixes and compiler warning eliminations.
* fixed link error with boost 1.50.
* fixed make installer script which previously would not install
mdds/compat headers.
* flat_segment_tree
* fixed a bug in its iterator implementation, which previously would
always treat the last valid position before the end position as
the end position. This fix affects both in const_iterator and
const_reverse_iterator.
mdds 0.6.0
* all
* added MSVS Solution file, to make it easier to build unit test
programs on Windows.
* mixed_type_matrix
* improved performance of size() method by caching it.
* multi_type_vector (new)
* new data structure to support efficient storage of data of different
types.
* multi_type_matrix (new)
* new data structure to eventually replace mixed_type_matrix. It uses
multi_type_vector as its backend storage.
mdds 0.5.4
* segment_tree
* fixed build breakage, to allow it to be buildable when UNIT_TEST
is not defined.
* fixed a crasher with MSVC when comparing iterators of empty
search_result instances.
* point_quad_tree
* fixed a bug where de-referencing copied search_result iterators
would return an uninitialized node data.
mdds 0.5.3
* mixed_type_matrix
* re-implemented the filled storage for better performance, with two
separate implementations for zero and emtpy matrix types. The
newer implementation should improve object creation time
considerably.
mdds 0.5.2
* flat_segment_tree
* fixed a crash on assignment by properly implementing assignment
operator().
* fixed several bugs in shift_right():
* shifting of all existing nodes was not handled properly.
* leaf nodes were not properly linked under certain conditions.
* shifting with skip node option was not properly skipping the
node at insertion position when the insertion position was at
the leftmost node.
* implemented min_key(), max_key(), default_value(), clear() and
swap().
* fixed a bug in operator==() where two different containers were
incorrectly evaluated to be equal.
* added quickcheck test code.
mdds 0.5.1
* fixed build issues on Windows, using MSVC compilers.
mdds 0.5.0
* flat_segment_tree's search methods now return a std::pair of
const_iterator and bool, instead of just returning bool.
* fixed a weird enum value mis-handling with mixed_type_matrix when
compiled with MSVC++.
* added new insert() method to flat_segment_tree that takes a
positional hint in order to speed up insertion speed. Also, all
three insert() methods now return the start position of the
segment that an inserted segment belongs to.
* slight performance improvement on the insert methods of
flat_segment_tree.
* slight performance improvement on the iterators of
flat_segment_tree.
* re-organized the structure of flat_segment_tree to split it into
multiple headers.
* properly support prefix, docdir, includedir configure options.
* support DESTDIR environment variable for make install.
mdds 0.4.0
* implemented mixed_type_matrix.
mdds 0.3.1
* added support for boost::unordered_map (boost) and std::hash_map
(stlport) in addition to C++0x's std::unordered_map.
mdds 0.3.0
* implemented point_quad_tree.
mdds 0.2.1
* added example files on how to use these data structures.
* fixed a bug in segment_tree::search_result object, to make it work
with empty result set.
* fixed segment_tree to make it really usable outside of unit test
code.
mdds 0.2.0
* other general performance improvements.
* lots of code cleanups.
* support for search result iterator in segment_tree and
rectangle_set, for better search performance.
* implemented rectnagle_set.
* fixed lots of bugs in the segment_tree implementation.
mdds 0.1.2

Multi-Dimensional Data Structure (mdds)
=======================================
A collection of multi-dimensional data structure and indexing
algorithm.
Overview of data structures included in mdds
--------------------------------------------
This library implements the following data structures:
* segment_tree
* flat_segment_tree
* point_quad_tree
* multi_type_vector
* multi_type_matrix
* sorted_string_map
* trie_map
* packed_trie_map
* rtree
### Segment Tree
Segment tree is a balanced-binary-tree based data structure efficient
for detecting all intervals (or segments) that contain a given point.
The segments may overlap with each other. The end points of stored
segments are not inclusive, that is, when an interval spans from 2 to
6, an arbitrary point x within that interval can take a value of 2 <=
x < 6.
### Flat Segment Tree
Flat segment tree is a variant of segment tree that is designed to
store a collection of non-overlapping segments. This structure is
efficient when you need to store values associated with 1 dimensional
segments that never overlap with each other. Like segment tree,
stored segments' end points are non-inclusive.
### Point Quad Tree
Point quad tree stores 2-dimensional points and provides an efficient
way to query all points within specified rectangular region.
### Multi Type Vector
Multi-type vector allows storage of unspecified number of types in a single
logical array such that contiguous elements of identical type are stored in
contiguous segment in memory space.
### Multi Type Matrix
Multi-type matrix is a matrix structure that allows storage of four different
element types: numeric, string, boolean and empty. It uses multi-type vector as
its underlying storage.
### Sorted String Map
Sorted string map is a simple data structure that takes a pre-sorted list of
key-value pairs that are known at compile time, and allows efficient lookup.
It does not allocate memory to duplicate its content, as it directly uses the
pre-sorted list provided by the caller.
### Trie Map
Trie map is an associative container that stores multiple key-value pairs
where keys are stored in a trie structure to optimize for prefix searches.
### Packed Trie Map
Packed trie map is nearly identical to the trie map counterpart except that
this one is immutable. It packs all its content in a contiguous array for
optimum storage and lookup efficiency. This implementation is based on the
paper titled [Tightly Packed Tries: How to Fit Large Models into Memory, and Make them Load Fast, Too](https://www.aclweb.org/anthology/W09-1505/)
by Ulrich Germann, Eric Joanis, and Samuel Larkin.
### R-tree
[R-tree](https://en.wikipedia.org/wiki/R-tree) is a tree-based data structure
designed to store multi-dimensional geometric data with bounding boxes and
provide optimal performance on region- or point-based queries. The one
implemented in this library is a variant of R-tree known as
[R*-tree](https://en.wikipedia.org/wiki/R*_tree).

Description: Multi Dimension Data structure library -- headers
A collection of multi-dimensional data structure and indexing algorithm.
.
This is a C++ library, and is a collection of various data structures designed
to efficiently store and query multi-dimensional data for various
filtering criteria. Different structures are optimized for different
query needs.
.
This library is a source-code only library. It’s designed to be
header-only meaning that the user program does not need to link to any
additional shared library in order to use these data structures. The
data structures are all available as C++ templates.

## Note that this doesn't just cater to obsosete pre-3.x GCC compilers.

## (see the conditional assignment to $gccflag above).
## There are various ways to get dependency output from gcc. Here's
## why we pick this rather obscure method:
## - Don't want to use -MD because we'd like the dependencies to end
## up in a subdir. Having to rename by hand is ugly.
## (We might end up doing this anyway to support other compilers.)
## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like
## -MM, not -M (despite what the docs say). Also, it might not be
## supported by the other compilers which use the 'gcc' depmode.
## - Using -M directly means running the compiler twice (even worse
## than renaming).

## This next piece of magic avoids the "deleted header file" problem.
## The problem is that when a header file which appears in a .P file
## is deleted, the dependency causes make to die (because there is
## typically no way to rebuild the header). We avoid this by adding
## dummy dependencies for each header file. Too bad gcc doesn't do
## this for us directly.
## Some versions of gcc put a space before the ':'. On the theory
## that the space means something, we add a space to the output as
## well. hp depmode also adds that space, but also prefixes the VPATH
## to the object. Take care to not repeat it in the output.
## Some versions of the HPUX 10.20 sed can't process this invocation

Flat segment tree is a derivative of `segment tree
<https://en.wikipedia.org/wiki/Segment_tree>`_, and is designed to store
non-overlapping 1-dimensional range values such that *the values of the
neighboring ranges are guaranteed to be different.* An insertion of a range
value into this structure will always overwrite one or more existing ranges
that overlap with the new range. If an insertion of a new range would cause
any adjacent ranges to have the equal value, those ranges will be merged into
one range.
An instance of this structure is initialized with fixed lower and upper
bounaries, which will not change throughout the life time of the instance.
The flat segment tree structure consists of two parts: the leaf-node part
which also forms a doubly-linked list, and the non-leaf-node part which forms
a balanced-binary tree and is used only when performing tree-based queries.
The range values are stored in the leaf-nodes, while the non-leaf nodes are
used only for queries.
Quick start
-----------
The following code demonstrates a simple use case of storing non-overlapping
ranged values and performing queries using :cpp:class:`~mdds::flat_segment_tree`:
.. literalinclude:: ../example/flat_segment_tree.cpp
:language: C++
:lines: 29-61
Let's walk through this code step-by-step. The first step is to declare the
instance::
// Define the begin and end points of the whole segment, and the default
// value.
fst_type db(0, 500, 0);
Here, the first and second arguments specify the lower and upper boundaries of
the whole segment. The third argument specifies the value for the empty
segments. What this line does is to create a new instance and initializes it
with one initial segment ranging from 0 to 500 with a value of 0.
.. figure:: _static/images/fst_example1_initial.png
:align: center
Internally, this initial range is represented by two leaf nodes, with the
first one storing the start key and the value for the segment both of which
happen to be 0 in this example, and the second one storing the end key of 500.
The following lines insert two new segments into this structure::
db.insert_front(10, 20, 10);
db.insert_back(50, 70, 15);
The first line inserts a segment ranging from 10 to 20 with a value of 10, and
the second line from 50 to 70 with a value of 15.
.. figure:: _static/images/fst_example1_insert1.png
:align: center
You can insert a new segment either via :cpp:func:`~mdds::flat_segment_tree::insert_front`
or :cpp:func:`~mdds::flat_segment_tree::insert_back`. The end result will be
the same regardless of which method you use; the difference is that
:cpp:func:`~mdds::flat_segment_tree::insert_front` begins its search for
the insertion point from the first node associated with the minimum key value,
whereas :cpp:func:`~mdds::flat_segment_tree::insert_back` starts its search
from the last node associated with the maximum key value.
At this point, the tree contains six leaf nodes in total to represent all
stored segments. Note that one leaf node represents both the end of a segment
and the start of the adjacent segment that comes after it, unless it's either
the first or the last node.
The next line inserts another segment ranging from 60 to 65 having a value of
5::
db.insert_back(60, 65, 5);
As this new segment overlaps with the existing segment of 50 to 70, it will
cut into a middle part of that segment to make room for itself. At this point,
the tree contains eight leaf nodes representing seven segments in total.
.. figure:: _static/images/fst_example1_insert2.png
:align: center
The next part queries the value associated with a key value of 15 via
:cpp:func:`~mdds::flat_segment_tree::search`::
int value = -1;
long beg = -1, end = -1;
// Perform linear search. This doesn't require the tree to be built
// beforehand. Note that the begin and end point parameters are optional.
db.search(15, value, &beg, &end);
cout << "The value at 15 is " << value << ", and this segment spans from " << beg << " to " << end << endl;;
When executing this code, you will see the following output:
.. code-block:: none
The value at 15 is 10, and this segment spans from 10 to 20
One thing to note is that the :cpp:func:`~mdds::flat_segment_tree::search`
method performs a linear search which involves traversing only through
the leaf nodes of the structure in order to find the target segment. As such,
the worst-case lookup performance is directly proportional to the number of
linear nodes.
There is another way to perform the query with better worse-case performance,
that is through :cpp:func:`~mdds::flat_segment_tree::search_tree` as seen in
the following code::
// Don't forget to build tree before calling search_tree().
db.build_tree();
// Perform tree search. Tree search is generally a lot faster than linear
// search, but requires the tree to be built beforehand.
db.search_tree(62, value, &beg, &end);
cout << "The value at 62 is " << value << ", and this segment spans from " << beg << " to " << end << endl;;
The signature of the :cpp:func:`~mdds::flat_segment_tree::search_tree` method
is identical to that of the :cpp:func:`~mdds::flat_segment_tree::search` method
except for the name. This code generates the following output:
.. code-block:: none
The value at 62 is 5, and this segment spans from 60 to 65
Query via :cpp:func:`~mdds::flat_segment_tree::search_tree` generally performs
better since it traverses through the search tree to find the target segment.
But it does require the search tree to be built ahead of time by calling
:cpp:func:`~mdds::flat_segment_tree::build_tree`.
Iterate through stored segments
-------------------------------
:cpp:class:`~mdds::flat_segment_tree` supports two types of iterators to allow
you to iterate through the segments stored in your tree. The first way is to
iterate through the individual leaf nodes one at a time by using
:cpp:func:`~mdds::flat_segment_tree::begin` and :cpp:func:`~mdds::flat_segment_tree::end`::
for (auto it = db.begin(); it != db.end(); ++it)
{
cout << "key: " << it->first << "; value: " << it->second << endl;
}
Each iterator value contains a pair of two values named ``first`` and ``second``,
with the first one being the key of the segment that the node initiates, and the
second one being the value associated with that segment. When executing this
code with the tree from the example code above, you'll get the following output:
.. code-block:: none
key: 0; value: 0
key: 10; value: 10
key: 20; value: 0
key: 50; value: 15
key: 60; value: 5
key: 65; value: 15
key: 70; value: 0
key: 500; value: 0
Each node stores the start key and the value of the segment it initiates, and
the key stored in each node is also the end key of the segment that the
previous node initiates except for the first node.
except
for the last node, which stores the end key of the segment the previous note
initiates. Note that the value stored in the last node is not associated with
any of the segments stored in the tree; in fact it is the default value for
empty segments.
One thing to keep in mind is that :cpp:class:`~mdds::flat_segment_tree` does
not support mutable iterators that let you modify the stored keys or values.
.. note::
:cpp:class:`~mdds::flat_segment_tree` does not support mutable iterators;
you can only traverse the values in a read-only fashion.
You can also use range-based for loop to iterate through the leaf nodes in a
similar fashion::
for (const auto& node : db)
{
cout << "key: " << node.first << "; value: " << node.second << endl;
}
The output from this code is identical to that from the previous one.
Now, one major inconvenience of navigating through the individual leaf nodes
one node at a time is that you need to keep track of the start and end points
of each segment if you need to operate on the segments rather than the nodes
that comprise the segments. The good news is that :cpp:class:`~mdds::flat_segment_tree`
does provide a way to iterate through the segments directly as the following
code demonstrates::
for (auto it = db.begin_segment(); it != db.end_segment(); ++it)
{
cout << "start: " << it->start << "; end: " << it->end << "; value: " << it->value << endl;
}
This code uses :cpp:func:`~mdds::flat_segment_tree::begin_segment` and
:cpp:func:`~mdds::flat_segment_tree::end_segment` to iterate through one
segment at a time with each iterator value containing ``start``, ``end`` and
``value`` members that correspond with the start key, end key and the value of
the segment, respectively. Running this code produces the following output:
.. code-block:: none
start: 0; end: 10; value: 0
start: 10; end: 20; value: 10
start: 20; end: 50; value: 0
start: 50; end: 60; value: 15
start: 60; end: 65; value: 5
start: 65; end: 70; value: 15
start: 70; end: 500; value: 0

Multi Type Vector
=================
Quick start
-----------
The following code demonstrates a simple use case of storing values of double
and :cpp:class:`std::string` types in a single container using :cpp:type:`~mdds::multi_type_vector`.
.. literalinclude:: ../example/multi_type_vector.cpp
:language: C++
:start-after: //!code-start
:end-before: //!code-end
You'll see the following console output when you compile and execute this code:

.. figure:: _static/images/mtv_block_structure.png
:align: center
Logical structure between the primary array, blocks, and element blocks.
Each multi_type_vector instance maintains a logical storage structure of one
primary array containing one or more blocks each of which consists of ``type``,
``position``, ``size`` and ``data`` members:
* ``type`` - numeric value representing the block type.
* ``position`` - numeridc value representing the logical position of the first
element of the block.
* ``size`` - number of elements present in the block a.k.a its logical size.
* ``data`` - pointer to the secondary storage (element block) storing the element
values.
In this example code, the ``type`` member is referenced to determine its block
type and its logical size is determined from the ``size`` member. For the
numeric and string blocks, their ``data`` members, which should point to the
memory addresses of their respective element blocks, are dereferenced in order
to print out their element values to stdout inside the ``print_block`` function.
Use custom event handlers
-------------------------
It is also possible to define custom event handlers that get called when
certain events take place. To define custom event handlers, you need to
define either a class or a struct that has the following methods:
* **void element_block_acquired(mdds::mtv::base_element_block* block)**
* **void element_block_released(mdds::mtv::base_element_block* block)**
as its public methods, specify it as type named ``event_func`` in a trait struct,
and pass it as the second template argument when instantiating your
:cpp:type:`~mdds::multi_type_vector` type. Refer to :cpp:type:`mdds::mtv::empty_event_func`
for the detail on when each event handler method gets triggered.
The following code example demonstrates how this all works:
.. literalinclude:: ../example/multi_type_vector_event1.cpp
:language: C++
:start-after: //!code-start
:end-before: //!code-end
You'll see the following console output when you compile and execute this code:
.. code-block:: none
inserting string 'foo'...
* element block acquired
inserting string 'bah'...
inserting int 100...
* element block acquired
emptying the container...
* element block released
* element block released
exiting program...
In this example, the **element_block_acquired** handler gets triggered each
time the container creates (thus acquires) a new element block to store a value.
It does *not* get called when a new value is appended to a pre-existing element
block. Similarly, the **element_block_releasd** handler gets triggered each
time an existing element block storing non-empty values gets deleted. One
thing to keep in mind is that since these two handlers respond to events related
to element blocks which are owned by non-empty blocks in the primary array,
and empty blocks don't store any element block instances, creations or deletions
of empty blocks don't trigger these event handlers.
The trait also allows you to configure other behaviors of :cpp:type:`~mdds::multi_type_vector`.
Refer to :cpp:type:`mdds::mtv::default_trait` for all available parameters.
Get raw pointer to element block array
--------------------------------------
Sometimes you need to expose a pointer to an element block array
especially when you need to pass such an array pointer to C API that
requires one. You can do this by calling the ``data`` method of the
element_block template class . This works since the element block
internally just wraps :cpp:class:`std::vector` (or
:cpp:class:`std::deque` in case the ``MDDS_MULTI_TYPE_VECTOR_USE_DEQUE``
preprocessing macro is defined), and its ``data`` method simply exposes
vector's own ``data`` method which returns the memory location of its
internal array storage.
The following code demonstrates this by exposing raw array pointers to the
internal arrays of numeric and string element blocks, and printing their
element values directly from these array pointers.
.. literalinclude:: ../example/multi_type_vector_element_block1.cpp
:language: C++
:start-after: //!code-start
:end-before: //!code-end
Compiling and execute this code produces the following output:

Traverse multiple multi_type_vector instances "sideways"
--------------------------------------------------------
In this section we will demonstrate a way to traverse multiple instances of
:cpp:type:`~mdds::multi_type_vector` "sideways" using the
:cpp:class:`mdds::mtv::collection` class. What this class does is to wrap
multiple instances of :cpp:type:`~mdds::multi_type_vector` and generate
iterators that let you iterate the individual element values collectively in
the direction orthogonal to the direction of the individual vector instances.
The best way to explain this feature is to use a spreadsheet analogy. Let's
say we are implementing a data store to store a 2-dimensional tabular data
where each cell in the data set is associated with row and column indices.
Each cell may store a value of string type, integer type, numeric type, etc.
And let's say that the data looks like the following spreadsheet data:
.. figure:: _static/images/mtv_collection_sheet.png
:align: center
It consists of five columns, with each column storing 21 rows of data. The
first row is a header row, followed by 20 rows of values. In this example, We
will be using one :cpp:type:`~mdds::multi_type_vector` instance for each
column thus creating five instances in total, and store them in a
``std::vector`` container.
The declaration of the data store will look like this:
.. literalinclude:: ../example/mtv_collection.cpp
:language: C++
:start-after: //!code-start: declare
:end-before: //!code-end: declare
:dedent: 4
The first two lines specify the concrete :cpp:type:`~mdds::multi_type_vector`
type used for each individual column and the collection type that wraps the
columns. The third line instantiates the ``std::vector`` instance to store
the columns, and we are setting its size to five to accommodate for five
columns. We will make use of the collection_type later in this example after
the columns have been populated.
Now, we need to populate the columns with values. First, we are setting the
header row:
.. literalinclude:: ../example/mtv_collection.cpp
:language: C++
:start-after: //!code-start: header-row
:end-before: //!code-end: header-row
:dedent: 4
We are then filling each column individually from column 1 through column 5.
First up is column 1:
.. literalinclude:: ../example/mtv_collection.cpp
:language: C++
:start-after: //!code-start: column-1
:end-before: //!code-end: column-1
:dedent: 4
Hopefully this code is straight-forward. It initializes an array of values
and push them to the column one at a time via
:cpp:func:`~mdds::mtv::soa::multi_type_vector::push_back`. Next up is column 2:
.. literalinclude:: ../example/mtv_collection.cpp
:language: C++
:start-after: //!code-start: column-2
:end-before: //!code-end: column-2
:dedent: 4
This is similar to the code for column 1, except that because we are using an
array of string literals which implicitly becomes an initializer list of type
``const char*``, we need to explicitly specify the type for the
:cpp:func:`~mdds::mtv::soa::multi_type_vector::push_back` call to be ``std::string``.
The code for column 3 is very similar to this:
.. literalinclude:: ../example/mtv_collection.cpp
:language: C++
:start-after: //!code-start: column-3
:end-before: //!code-end: column-3
:dedent: 4
Populating column 4 needs slight pre-processing. We are inserting a string
value of "unknown" in lieu of an integer value of -1. Therefore the following
code will do:
.. literalinclude:: ../example/mtv_collection.cpp
:language: C++
:start-after: //!code-start: column-4
:end-before: //!code-end: column-4
:dedent: 4
Finally, the last column to fill, which uses the same logic as for columns 2
and 3:
.. literalinclude:: ../example/mtv_collection.cpp
:language: C++
:start-after: //!code-start: column-5
:end-before: //!code-end: column-5
:dedent: 4
At this point, the content we've put into the ``columns`` variable roughly
reflects the tabular data shown at the beginning of this section. Now we can
use the collection type we've declared earlier to wrap the columns:
.. literalinclude:: ../example/mtv_collection.cpp
:language: C++
:start-after: //!code-start: wrap
:end-before: //!code-end: wrap
:dedent: 4
We are naming this variable ``rows`` since what we are doing with this wrapper
is to traverse the content of the tabular data in row-wise direction. For
this reason, calling it ``rows`` is quite fitting.
The :cpp:class:`~mdds::mtv::collection` class offers some flexibility as to
how the instances that you are trying to traverse orthogonally are stored.
That being said, you must meet the following prerequisites when passing the
collection of vector instances to the constructor of the
:cpp:class:`~mdds::mtv::collection` class:
1. All :cpp:type:`~mdds::multi_type_vector` instances that comprise the
collection must be of the same logical length i.e. their
:cpp:func:`~mdds::mtv::soa::multi_type_vector::size` methods must all return the same
value.
2. The instances in the collection must be stored in the source container
either as
* concrete instances (as in this example),
* as pointers, or
* as heap instances wrapped within smart pointer class such as
``std::shared_ptr`` or ``std::unique_ptr``.
Although we are storing the vector instances in a ``std::vector`` container in
this example, you have the flexibility to pick a different type of container
to store the individual vector instances as long as it provides STL-compatible
standard iterator functionality.
Additionally, when using the :cpp:class:`~mdds::mtv::collection` class, you
must ensure that the content of the vector instances that it references will
not change for the duration of its use.
Finally, here is the code that does the traversing:
.. literalinclude:: ../example/mtv_collection.cpp
:language: C++
:start-after: //!code-start: traverse-row
:end-before: //!code-end: traverse-row
:dedent: 4
It's a simple for-loop, and in each iteration you get a single cell node that
contains metadata about that cell including its value. The node contains the
following members:
* ``type`` - an integer value representing the type of the value.
* ``index`` - a 0-based index of the :cpp:type:`~mdds::multi_type_vector`
instance within the collection. You can think of this as column index in
this example.
* ``position`` - a 0-based logical element position within each
:cpp:type:`~mdds::multi_type_vector` instance. You can think of this as
row index in this example.
In the current example we are only making use of the ``type`` and ``index``
members, but the ``position`` member will be there if you need it.
The node also provides a convenient ``get()`` method to fetch the value of the
cell. This method is a template method, and you need to explicitly specify
the element block type in order to access the value.
When executing this code, you will see the following outout:
.. code-block:: none
ID | Make | Model | Year | Color
1 | Nissan | Frontier | 1998 | Turquoise
2 | Mercedes-Benz | W201 | 1986 | Fuscia
3 | Nissan | Frontier | 2009 | Teal
4 | Suzuki | Equator | unknown | Fuscia
5 | Saab | 9-5 | unknown | Green
6 | Subaru | Tribeca | 2008 | Khaki
7 | GMC | Yukon XL 2500 | 2009 | Pink
8 | Mercedes-Benz | E-Class | 2008 | Goldenrod
9 | Toyota | Camry Hybrid | 2010 | Turquoise
10 | Nissan | Frontier | 2001 | Yellow
11 | Mazda | MX-5 | 2008 | Orange
12 | Dodge | Ram Van 1500 | 2000 | Goldenrod
13 | Ford | Edge | unknown | Fuscia
14 | Bentley | Azure | 2009 | Goldenrod
15 | GMC | Sonoma Club Coupe | 1998 | Mauv
16 | Audi | S4 | 2013 | Crimson
17 | GMC | 3500 Club Coupe | 1994 | Turquoise
18 | Mercury | Villager | 2000 | Teal
19 | Pontiac | Sunbird | 1990 | Indigo
20 | BMW | 3 Series | 1993 | LKhaki
which clearly shows that the code has traversed the content of the tabular
data horizontally across columns as intended.
Now, one feature that may come in handy is the ability to limit the iteration
range within the collection. You can do that by calling either
:cpp:func:`~mdds::mtv::collection::set_collection_range` to limit the column
range or :cpp:func:`~mdds::mtv::collection::set_element_range` to limit the
row range, or perhaps both.
Let's see how this works in the current example. Here, we are going to limit
the iteration range to only columns 2 and 3, and rows 2 through 11. The following
code will set this limit:
.. literalinclude:: ../example/mtv_collection.cpp
:language: C++
:start-after: //!code-start: limit-range
:end-before: //!code-end: limit-range
:dedent: 4
Then iterate through the collection once again:
.. literalinclude:: ../example/mtv_collection.cpp
:language: C++
:start-after: //!code-start: traverse-row-range
:end-before: //!code-end: traverse-row-range
:dedent: 4
This code is nearly identical to the previous one except for the index values
used to control when to insert column separators and line breaks at the top
and bottom of each iteration. When executing this code, you'll see the
following output:
.. code-block:: none
Nissan | Frontier
Mercedes-Benz | W201
Nissan | Frontier
Suzuki | Equator
Saab | 9-5
Subaru | Tribeca
GMC | Yukon XL 2500
Mercedes-Benz | E-Class
Toyota | Camry Hybrid
Nissan | Frontier
which clearly shows that your iteration range did indeed shrink as expected.
Performance Considerations
--------------------------
Select SoA or AoS storage types
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
If you instantiate a multi_type_vector instance via
:cpp:type:`mdds::multi_type_vector`, which is an alias type for
:cpp:class:`mdds::mtv::soa::multi_type_vector`, you will be using the
structure-of-arrays (SoA) variant of its implementation which is new in 2.0.
Prior to 2.0, multi_type_vector used the array-of-structures (AoS) layout which
is still available post 2.0 via :cpp:class:`mdds::mtv::aos::multi_type_vector`
in case you need it.
Note, however, that the SoA variant generally yields better overall performance
since it can make more efficient use of CPU caches. It is therefore highly
recommended that you stick with the SoA variant unless you have a specific
reason not to.
Also note that both variants are API compatibile with each other.
Use of position hints to avoid the cost of block position lookup
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Consider the following example code:
.. literalinclude:: ../example/multi_type_vector_pos_hint.cpp
:language: C++
:start-after: //!code-start: no-pos-hint
:end-before: //!code-end: no-pos-hint
:dedent: 4
which, when executed, may take quite sometime to complete especially when you
are using an older version of mdds. This particular example exposes one
weakness that multi_type_vector has; because it needs to first look up the
position of the block to operate with, and that lookup *always* starts from the
first block, the time it takes to find the correct block increases as the number
of blocks goes up. This example demonstrates the worst case scenario of such
lookup complexity since it always inserts the next value at the last block
position.
Fortunately, there is a simple solution to this which the following code
demonstrates:
.. literalinclude:: ../example/multi_type_vector_pos_hint.cpp
:language: C++
:start-after: //!code-start: pos-hint
:end-before: //!code-end: pos-hint
:dedent: 4
Compiling and executing this code should take only a fraction of a second.
The only difference between the second example and the first one is that the
second one uses an interator as a position hint to keep track of the position of
the last modified block. Each
:cpp:func:`~mdds::mtv::soa::multi_type_vector::set` method call returns an
iterator which can then be passed to the next
:cpp:func:`~mdds::mtv::soa::multi_type_vector::set` call as the position hint.
Because an iterator object internally stores the location of the block the value
was inserted to, this lets the method to start the block position lookup process
from the last modified block, which in this example is always one block behind
the one the new value needs to go. Using the big-O notation, the use of the
position hint essentially turns the complexity of O(n^2) in the first example
into O(1) in the second one if you are using an older version of mdds where the
block position lookup had a linear complexity.
This strategy should work with any methods in :cpp:type:`~mdds::multi_type_vector`
that take a position hint as the first argument.
Note that, if you are using a more recent version of mdds (1.6.0 or newer), the
cost of block position lookup is significantly lessoned thanks to the switch to
binary search in performing the lookup.
.. note::
If you are using mdds 1.6.0 or newer, the cost of block position lookup is
much less significant even without the use of position hints. But the benefit
of using position hints may still be there. It's always a good idea to profile
your specific use case and decide whether the use of position hints is worth
it.
One important thing to note is that, as a user, you must ensure that the position
hint you pass stays valid between the calls. A position hint becomes invalid when
the content of the container changes. A good strategy to maintain a valid position
hint is to always receive the iterator returned from the mutator method you called
to which you passed the previous position hint, which is what the code above does.
Passing an invalid position hint to a method that takes one may result in invalid
memory access or otherwise in some sort of undefined behavior.

Block shifting performance and loop-unrolling factor
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The introduction of binary search in the block position lookup implementation
in version 1.6 has significantly improved its lookup performance, but has
also resulted in slight performance hit when shifting blocks during value
insertion. This is because when shifting the logical positions of the blocks
below the insertion point, their head positions need to be re-calculated to
account for their new positions.
The good news is that the switch to the structure-of-arrays (SoA) storage
layout in 2.0 alone may bring subtle but measurable improvement in the
block position adjustment performance due to the logical block positions now
being stored in a separate array thereby improving its cache efficiency. In
reality, however, this was somewhat dependent on the CPU types since some CPU's
didn't show any noticeable improvements or even showed worse performance, while
other CPU types showed consistent improvements with SoA over AoS.
Another factor that may play a role is `loop unrolling <https://en.wikipedia.org/wiki/Loop_unrolling>`_
factor which can be configured via the :cpp:var:`~mdds::mtv::default_trait::loop_unrolling`
variable in your custom trait type if you use version 2.0 or newer. This variable
is an enum class of type :cpp:type:`mdds::mtv::lu_factor_t` which enumerates
several pre-defined loop-unrolling factors as well as some SIMD features.
The hardest part is to figure out which loop unrolling factor is the best option
in your runtime environment, since it is highly dependent on the environment.
Luckily mdds comes with a tool called `runtime-env <https://gitlab.com/mdds/mdds/-/tree/master/tools/runtime-env>`_
which, when run, will perform some benchmarks and give you the best loop-unrolling
factor in your runtime environment. Be sure to build this tool with the same
compiler and compiler flags as your target program in order for this tool to give
you a representative answer.
Debugging
---------
Tracing of public methods
^^^^^^^^^^^^^^^^^^^^^^^^^
When using :cpp:class:`~mdds::mtv::soa::multi_type_vector` to handle a series
of data reads and writes in an non-trivial code base, sometimes you may find
yourself needing to track which methods are getting called when following a
certain code path during a debugging session. In such a situation, you can enable
an optional trace method which gets called whenever a public method of :cpp:class:`~mdds::mtv::soa::multi_type_vector`
is called.
First, you need to define a preprocessor macro named
``MDDS_MULTI_TYPE_VECTOR_DEBUG`` before including the header for
:cpp:class:`~mdds::mtv::soa::multi_type_vector`:
.. literalinclude:: ../example/multi_type_vector_debug_trace.cpp
:language: C++
:start-after: //!code-start: header
:end-before: //!code-end: header
to enable additional debug code. In this example the value of the macro is
set to 1, but it doesn't matter what the value of the macro is, as long as it
is defined. You can also define one as a compiler option as well.
Once defined, the next step is to add a ``trace`` method as a static function to
the trait type you pass as a template argument of multi_type_vector:
.. literalinclude:: ../example/multi_type_vector_debug_trace.cpp
:language: C++
:start-after: //!code-start: types
:end-before: //!code-end: types
Here, we are simply inheriting our trait type from the
:cpp:class:`~mdds::mtv::default_trait` type and simply adding a static ``trace``
function to it, and passing this trait type to the mtv_type definition below.
This trace function must take one argument of type
:cpp:class:`mdds::mtv::trace_method_properties_t` which includes various
properties of the traced call. In this example, we are simply printing the
properties named
:cpp:member:`~mdds::mtv::trace_method_properties_t::function_name` and
:cpp:member:`~mdds::mtv::trace_method_properties_t::function_args` each time a
traced method is called. Both of these properties are printable string types.
Note that this ``trace`` function is entirely optional; the code will compile
fine even when it's not defined. Also, it must be declared as static for it to
be called.
Let's instantiate an object of ``mtv_type``, call some of its methods and see
what happens. When executing the following code:
.. literalinclude:: ../example/multi_type_vector_debug_trace.cpp
:language: C++
:start-after: //!code-start: main
:end-before: //!code-end: main
:dedent: 4
You will see the following output:
.. code-block:: text
function:
name: multi_type_vector
args: init_size=10
function:
name: set
args: pos=0; value=? (type=5)
function:
name: set
args: pos=2; value=? (type=1)
function:
name: set
args: pos=4; value=? (type=3)
function:
name: ~multi_type_vector
args:
The :cpp:member:`~mdds::mtv::trace_method_properties_t::function_name`
property is hopefully self-explanatory. The
:cpp:member:`~mdds::mtv::trace_method_properties_t::function_args` property is
a single string value containing the information about the function's
arguments and optionally their values if their values are known to be
printable. If the value of an argument cannot be printed, ``?`` is placed
instead. For some argument types, an additional information is displayed e.g.
``(type=5)`` in the above output which indicates that the type of the value
being passed to the function is :cpp:var:`~mdds::mtv::element_type_int32`.
If you want to limit your tracing to a specific function type or types, you
can make use of the :cpp:member:`~mdds::mtv::trace_method_properties_t::type`
property which specifies the type of the traced method. Likewise, if you want
to only trace methods of a certain instance, use
:cpp:member:`~mdds::mtv::trace_method_properties_t::instance` to filter the
incoming trace calls based on the memory addresses of the instances whose
methods are being traced.
Note that this feature is available for version 2.0.2 and newer, and currently
only available for the SoA variant of :cpp:class:`~mdds::mtv::soa::multi_type_vector`.
.. note::
This feature is only available for version 2.0.2 and newer, and only for the
SoA variant.

Trie Maps
=========
Examples
--------
Populating Trie Map
^^^^^^^^^^^^^^^^^^^
This section illustrates how to use :cpp:class:`~mdds::trie_map` to build a
database of city populations and perform prefix searches. In this example,
we will use the 2013 populations of cities in North Carolina, and use the city
names as keys.
Let's define the type first::
using trie_map_type = mdds::trie_map<mdds::trie::std_string_trait, int>;
The first template argument specifies the trait of the key. In this example,
we are using a pre-defined trait for std::string, which is defined in
:cpp:type:`~mdds::trie::std_string_trait`. The second template argument
specifies the value type, which in this example is simply an ``int``.
Once the type is defined, the next step is instantiation::
trie_map_type nc_cities;
It's pretty simple as you don't need to pass any arguments to the constructor.
Now, let's populate this data structure with some population data::
// Insert key-value pairs.
nc_cities.insert("Charlotte", 792862);
nc_cities.insert("Raleigh", 431746);
nc_cities.insert("Greensboro", 279639);
nc_cities.insert("Durham", 245475);
nc_cities.insert("Winston-Salem", 236441);
nc_cities.insert("Fayetteville", 204408);
nc_cities.insert("Cary", 151088);
nc_cities.insert("Wilmington", 112067);
nc_cities.insert("High Point", 107741);
nc_cities.insert("Greenville", 89130);
nc_cities.insert("Asheville", 87236);
nc_cities.insert("Concord", 83506);
nc_cities.insert("Gastonia", 73209);
nc_cities.insert("Jacksonville", 69079);
nc_cities.insert("Chapel Hill", 59635);
nc_cities.insert("Rocky Mount", 56954);
nc_cities.insert("Burlington", 51510);
nc_cities.insert("Huntersville", 50458);
nc_cities.insert("Wilson", 49628);
nc_cities.insert("Kannapolis", 44359);
nc_cities.insert("Apex", 42214);
nc_cities.insert("Hickory", 40361);
nc_cities.insert("Goldsboro", 36306);
It's pretty straight-forward. Each :cpp:func:`~mdds::trie_map::insert` call
expects a pair of string key and an integer value. You can insert your data
in any order regardless of key's sort order.
Now that the data is in, let's perform prefix search to query all cities whose
name begins with "Cha"::
cout << "Cities that start with 'Cha' and their populations:" << endl;
auto results = nc_cities.prefix_search("Cha");
for (const auto& kv : results)
{
cout << " " << kv.first << ": " << kv.second << endl;
}
You can perform prefix search via :cpp:func:`~mdds::trie_map::prefix_search`
method, which returns a results object that can be iterated over using a range-based
for loop. Running this code will produce the following output:
.. code-block:: none
Cities that start with 'Cha' and their populations:
Chapel Hill: 59635
Charlotte: 792862
Let's perform another prefix search, this time with a prefix of "W"::
cout << "Cities that start with 'W' and their populations:" << endl;
results = nc_cities.prefix_search("W");
for (const auto& kv : results)
{
cout << " " << kv.first << ": " << kv.second << endl;
}
You'll see the following output when running this code:
.. code-block:: none
Cities that start with 'W' and their populations:
Wilmington: 112067
Wilson: 49628
Winston-Salem: 236441
Note that the results are sorted in key's ascending order.
.. note::
Results from the prefix search are sorted in key's ascending order.
Creating Packed Trie Map from Trie Map
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
There is also another variant of trie called :cpp:class:`~mdds::packed_trie_map`
which is designed to store all its data in contiguous memory region. Unlike
:cpp:class:`~mdds::trie_map` which is mutable, :cpp:class:`~mdds::packed_trie_map`
is immutable; once populated, you can only perform queries and it is no longer
possible to add new entries into the container.
One way to create an instance of :cpp:class:`~mdds::packed_trie_map` is from
:cpp:class:`~mdds::trie_map` by calling its :cpp:func:`~mdds::trie_map::pack`
method::
auto packed = nc_cities.pack();
The query methods of :cpp:class:`~mdds::packed_trie_map` are identical to those
of :cpp:class:`~mdds::trie_map`. For instance, performing prefix search to find
all entries whose key begins with "C" can be done as follows::
cout << "Cities that start with 'C' and their populations:" << endl;
auto packed_results = packed.prefix_search("C");
for (const auto& kv : packed_results)
{
cout << " " << kv.first << ": " << kv.second << endl;
}
Running this code will generate the following output:
.. code-block:: none
Cities that start with 'C' and their populations:
Cary: 151088
Chapel Hill: 59635
Charlotte: 792862
Concord: 83506
You can also perform an exact-match query via :cpp:func:`~mdds::packed_trie_map::find`
method which returns an iterator associated with the key-value pair entry::
// Individual search.
auto it = packed.find("Wilmington");
cout << "Population of Wilmington: " << it->second << endl;
You'll see the following output with this code:
.. code-block:: none
Population of Wilmington: 112067
What if you performed an exact-match query with a key that doesn't exist in the
container? You will basically get the end iterator position as its return value.
Thus, running this code::
// You get an end position iterator when the container doesn't have the
// specified key.
it = packed.find("Asheboro");
cout << "Population of Asheboro: ";
if (it == packed.end())
cout << "not found";
else
cout << it->second;
cout << endl;
will generate the following output:
.. code-block:: none
Population of Asheboro: not found
The complete source code for the examples in these two sections is available
`here <https://gitlab.com/mdds/mdds/-/blob/master/example/trie_map.cpp>`__.
Using Packed Trie Map directly
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
In the previous example, we showed a way to create an instance of :cpp:class:`~mdds::packed_trie_map`
from a populated instance of :cpp:class:`~mdds::trie_map`. There is also a way
to instantiate and populate an instance of :cpp:class:`~mdds::packed_trie_map`
directly, and that is what we will cover in this section.
First, declare the type::
using trie_map_type = mdds::packed_trie_map<mdds::trie::std_string_trait, int>;
Once again, we are using the pre-defined trait for std::string as its key, and int
as its value type. The next step is to prepare its entries ahead of time::
trie_map_type::entry entries[] =
{
{ MDDS_ASCII("Apex"), 42214 },
{ MDDS_ASCII("Asheville"), 87236 },
{ MDDS_ASCII("Burlington"), 51510 },
{ MDDS_ASCII("Cary"), 151088 },
{ MDDS_ASCII("Chapel Hill"), 59635 },
{ MDDS_ASCII("Charlotte"), 792862 },
{ MDDS_ASCII("Concord"), 83506 },
{ MDDS_ASCII("Durham"), 245475 },
{ MDDS_ASCII("Fayetteville"), 204408 },
{ MDDS_ASCII("Gastonia"), 73209 },
{ MDDS_ASCII("Goldsboro"), 36306 },
{ MDDS_ASCII("Greensboro"), 279639 },
{ MDDS_ASCII("Greenville"), 89130 },
{ MDDS_ASCII("Hickory"), 40361 },
{ MDDS_ASCII("High Point"), 107741 },
{ MDDS_ASCII("Huntersville"), 50458 },
{ MDDS_ASCII("Jacksonville"), 69079 },
{ MDDS_ASCII("Kannapolis"), 44359 },
{ MDDS_ASCII("Raleigh"), 431746 },
{ MDDS_ASCII("Rocky Mount"), 56954 },
{ MDDS_ASCII("Wilmington"), 112067 },
{ MDDS_ASCII("Wilson"), 49628 },
{ MDDS_ASCII("Winston-Salem"), 236441 },
};
We need to do this since :cpp:class:`~mdds::packed_trie_map` is immutable, and
the only time we can populate its content is at instantiation time. Here, we
are using the :c:macro:`MDDS_ASCII` macro to expand a string literal to its
pointer value and size. Note that you need to ensure that the entries are sorted
by the key in ascending order.
.. warning::
When instantiating :cpp:class:`~mdds::packed_trie_map` directly with a static
set of entries, the entries must be sorted by the key in ascending order.
You can then pass this list of entries to construct the instance::
trie_map_type nc_cities(entries, MDDS_N_ELEMENTS(entries));
The :c:macro:`MDDS_N_ELEMENTS` macro will infer the size of a fixed-size array
from its static definition. Once it's instantiated, the rest of the example
for performing searches will be the same as in the previous section, which we
will not repeat here.
The complete source code for the example in this section is available
`here <https://gitlab.com/mdds/mdds/-/blob/master/example/packed_trie_map.cpp>`__.
Saving and loading Packed Trie Map instances
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
There are times when you need to save the state of a :cpp:class:`~mdds::packed_trie_map`
instance to a file, or an in-memory buffer, and load it back later. Doing that
is now possible by using the :cpp:func:`~mdds::packed_trie_map::save_state` and
:cpp:func:`~mdds::packed_trie_map::load_state` member methods of the
:cpp:class:`~mdds::packed_trie_map` class.
First, let's define the type of use::
using map_type = mdds::packed_trie_map<mdds::trie::std_string_trait, int>;
As with the previous examples, we will use ``std::string`` as the key type and
``int`` as the value type. In this example, we are going to use `the world's
largest cities and their 2018 populations
<https://en.wikipedia.org/wiki/List_of_largest_cities>`__ as the data to store
in the container.
The following code defines the entries::
std::vector<map_type::entry> entries =
{
{ MDDS_ASCII("Ahmedabad"), 7681000 },
{ MDDS_ASCII("Alexandria"), 5086000 },

};
It's a bit long as it contains entries for 81 cities. We are then going to
create an instance of the :cpp:class:`~mdds::packed_trie_map` class directly::
map_type cities(entries.data(), entries.size());
Let's print the size of the container to make sure the container has been
successfully populated::
cout << "Number of cities: " << cities.size() << endl;
You will see the following output:
.. code-block:: none
Number of cities: 81
if the container has been successfully populated. Now, let's run a prefix
search on names beginning with an 'S'::
cout << "Cities that begin with 'S':" << endl;
auto results = cities.prefix_search("S");
for (const auto& city : results)
cout << " * " << city.first << ": " << city.second << endl;
to make sure you get the following ten cities and their populations as the
output:
.. code-block:: none
Cities that begin with 'S':
* Saint Petersburg: 5383000
* Santiago: 6680000
* Sao Paulo: 21650000
* Seoul: 9963000
* Shanghai: 25582000
* Shenyang: 6921000
* Shenzhen: 11908000
* Singapore: 5792000
* Surat: 6564000
* Suzhou: 6339000
So far so good. Next, we will use the :cpp:func:`~mdds::packed_trie_map::save_state`
method to dump the internal state of this container to a file named **cities.bin**::
std::ofstream outfile("cities.bin", std::ios::binary);
cities.save_state(outfile);
This will create a file named **cities.bin** which contains a binary blob
representing the content of this container in the current working directory.
Run the ``ls -l cities.bin`` command to make sure the file has been created:
.. code-block:: none
-rw-r--r-- 1 kohei kohei 17713 Jun 20 12:49 cities.bin
Now that the state of the container has been fully serialized to a file, let's
work on restoring its content in another, brand-new instance of
:cpp:class:`~mdds::packed_trie_map`.
::
map_type cities_loaded;
std::ifstream infile("cities.bin", std::ios::binary);
cities_loaded.load_state(infile);
Here, we used the :cpp:func:`~mdds::packed_trie_map::load_state` method to
restore the state from the file we have previously created. Let's make sure
that this new instance has content equivalent to that of the original::
cout << "Equal to the original? " << std::boolalpha << (cities == cities_loaded) << endl;
If you see the following output:
.. code-block:: none
Equal to the original? true
then this new instance has equivalent contant as the original one. Let's also
make sure that it contains the same number of entries as the original::
cout << "Number of cities: " << cities_loaded.size() << endl;
Hopefully you will see the following output:
.. code-block:: none
Number of cities: 81
Lastly, let's run on this new instance the same prefix search we did on the
original instance, to make sure we still get the same results::
cout << "Cities that begin with 'S':" << endl;
auto results = cities_loaded.prefix_search("S");
for (const auto& city : results)
cout << " * " << city.first << ": " << city.second << endl;
You should see the following output:
.. code-block:: none
Cities that begin with 'S':
* Saint Petersburg: 5383000
* Santiago: 6680000
* Sao Paulo: 21650000
* Seoul: 9963000
* Shanghai: 25582000
* Shenyang: 6921000
* Shenzhen: 11908000
* Singapore: 5792000
* Surat: 6564000
* Suzhou: 6339000
which is the same output we saw in the first prefix search.

Saving Packed Trie Map with custom value type
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
In the previos example, you didn't have to explicitly specify the serializer type
to the :cpp:func:`~mdds::packed_trie_map::save_state` and
:cpp:func:`~mdds::packed_trie_map::load_state` methods, even though these two
methods require the serializer type as their template arguments. That's because
the library provides default serializer types for
* numeric value types i.e. integers, float and double,
* ``std::string``, and
* the standard sequence types, such as ``std::vector``, whose elements are of
numeric value types,
and the previous example used ``int`` as the value type.
In this section, we are going to illustrate how you can write your own custom
serializer to allow serialization of your own custom value type. In this example,
we are going to use `the list of presidents of the United States
<https://en.wikipedia.org/wiki/List_of_presidents_of_the_United_States>`__,
with the names of the presidents as the keys, and their years of inauguration
and political affiliations as the values.
We will use the following structure to store the values::
enum affiliated_party_t : uint8_t
{
unaffiliated = 0,
federalist,
democratic_republican,
democratic,
whig,
republican,
national_union,
republican_national_union,
};
struct us_president
{
uint16_t year;
affiliated_party_t party;
};
Each entry stores the year as a 16-bit integer and the affiliated party as an enum
value of 8-bit width.
Next, let's define the container type::
using map_type = mdds::packed_trie_map<mdds::trie::std_string_trait, us_president>;
As with the previous example, the first step is to define the entries that are
sorted by the keys, which in this case are the president's names::
std::vector<map_type::entry> entries =
{
{ MDDS_ASCII("Abraham Lincoln"), { 1861, republican_national_union } },
{ MDDS_ASCII("Andrew Jackson"), { 1829, democratic } },
{ MDDS_ASCII("Andrew Johnson"), { 1865, national_union } },
{ MDDS_ASCII("Barack Obama"), { 2009, democratic } },
{ MDDS_ASCII("Benjamin Harrison"), { 1889, republican } },
{ MDDS_ASCII("Bill Clinton"), { 1993, democratic } },
{ MDDS_ASCII("Calvin Coolidge"), { 1923, republican } },
{ MDDS_ASCII("Chester A. Arthur"), { 1881, republican } },
{ MDDS_ASCII("Donald Trump"), { 2017, republican } },
{ MDDS_ASCII("Dwight D. Eisenhower"), { 1953, republican } },
{ MDDS_ASCII("Franklin D. Roosevelt"), { 1933, democratic } },
{ MDDS_ASCII("Franklin Pierce"), { 1853, democratic } },
{ MDDS_ASCII("George H. W. Bush"), { 1989, republican } },
{ MDDS_ASCII("George W. Bush"), { 2001, republican } },
{ MDDS_ASCII("George Washington"), { 1789, unaffiliated } },
{ MDDS_ASCII("Gerald Ford"), { 1974, republican } },
{ MDDS_ASCII("Grover Cleveland 1"), { 1885, democratic } },
{ MDDS_ASCII("Grover Cleveland 2"), { 1893, democratic } },
{ MDDS_ASCII("Harry S. Truman"), { 1945, democratic } },
{ MDDS_ASCII("Herbert Hoover"), { 1929, republican } },
{ MDDS_ASCII("James A. Garfield"), { 1881, republican } },
{ MDDS_ASCII("James Buchanan"), { 1857, democratic } },
{ MDDS_ASCII("James K. Polk"), { 1845, democratic } },
{ MDDS_ASCII("James Madison"), { 1809, democratic_republican } },
{ MDDS_ASCII("James Monroe"), { 1817, democratic_republican } },
{ MDDS_ASCII("Jimmy Carter"), { 1977, democratic } },
{ MDDS_ASCII("John Adams"), { 1797, federalist } },
{ MDDS_ASCII("John F. Kennedy"), { 1961, democratic } },
{ MDDS_ASCII("John Quincy Adams"), { 1825, democratic_republican } },
{ MDDS_ASCII("John Tyler"), { 1841, whig } },
{ MDDS_ASCII("Lyndon B. Johnson"), { 1963, democratic } },
{ MDDS_ASCII("Martin Van Buren"), { 1837, democratic } },
{ MDDS_ASCII("Millard Fillmore"), { 1850, whig } },
{ MDDS_ASCII("Richard Nixon"), { 1969, republican } },
{ MDDS_ASCII("Ronald Reagan"), { 1981, republican } },
{ MDDS_ASCII("Rutherford B. Hayes"), { 1877, republican } },
{ MDDS_ASCII("Theodore Roosevelt"), { 1901, republican } },
{ MDDS_ASCII("Thomas Jefferson"), { 1801, democratic_republican } },
{ MDDS_ASCII("Ulysses S. Grant"), { 1869, republican } },
{ MDDS_ASCII("Warren G. Harding"), { 1921, republican } },
{ MDDS_ASCII("William Henry Harrison"), { 1841, whig } },
{ MDDS_ASCII("William Howard Taft"), { 1909, republican } },
{ MDDS_ASCII("William McKinley"), { 1897, republican } },
{ MDDS_ASCII("Woodrow Wilson"), { 1913, democratic } },
{ MDDS_ASCII("Zachary Taylor"), { 1849, whig } },
};
Note that we need to add numeric suffixes to the entries for Grover Cleveland,
who became president twice in two separate periods, in order to make the keys
for his entries unique.
Now, proceed to create an instance of :cpp:class:`~mdds::packed_trie_map`::
map_type us_presidents(entries.data(), entries.size());
and inspect its size to make sure it is instantiated properly::
cout << "Number of entries: " << us_presidents.size() << endl;
You should see the following output:
.. code-block:: none
Number of entries: 45
Before we proceed to save the state of this instance, let's define the custom
serializer type first::
struct us_president_serializer
{
union bin_buffer
{
char buffer[2];
uint16_t i16;
affiliated_party_t party;
};
static constexpr bool variable_size = false;
static constexpr size_t value_size = 3;
static void write(std::ostream& os, const us_president& v)
{
bin_buffer buf;
// Write the year value first.
buf.i16 = v.year;
os.write(buf.buffer, 2);
// Write the affiliated party value.
buf.party = v.party;
os.write(buf.buffer, 1);
}
static void read(std::istream& is, size_t n, us_president& v)
{
// For a fixed-size value type, this should equal the defined value size.
assert(n == 3);
bin_buffer buf;
// Read the year value.
is.read(buf.buffer, 2);
v.year = buf.i16;
// Read the affiliated party value.
is.read(buf.buffer, 1);
v.party = buf.party;
}
};
A custom value type can be either variable-size or fixed-size. For a variable-size
value type, each value segment is preceded by the byte length of that segment.
For a fixed-size value type, the byte length of all of the value segments
is written only once up-front, followed by one or more value segments of equal
byte length.
Since the value type in this example is fixed-size, we set the value of the
``variable_size`` static constant to false, and define the size of the value to 3 (bytes)
as the ``value_size`` static constant. Keep in mind that you need to define
the ``value_size`` constant *only* for fixed-size value types; if your value
type is variable-size, you can leave it out.
Additionally, you need to define two static methods - one for writing to the
output stream, and one for reading from the input stream. The write method
must have the following signature::
static void write(std::ostream& os, const T& v);
where the ``T`` is the value type. In the body of this method you write to the
output stream the bytes that represent the value. The length of the bytes you
write must match the size specified by the ``value_size`` constant.
The read method must have the following signature::
static void read(std::istream& is, size_t n, T& v);
where the ``T`` is the value type, and the ``n`` specifies the length of the
bytes you need to read for the value. For a fixed-size value type, the value
of ``n`` should equal the ``value_size`` constant. Your job is to read the
bytes off of the input stream for the length specified by the ``n``, and
populate the value instance passed to the method as the third argument.
Now that we have defined the custom serializer type, let's proceed to save the
state to a file::
std::ofstream outfile("us-presidents.bin", std::ios::binary);
us_presidents.save_state<us_president_serializer>(outfile);
This time around, we are specifying the serializer type explicitly as the template
argument to the :cpp:func:`~mdds::packed_trie_map::save_state` method. Otherwise
it is no different than what we did in the previous example.
Let's create another instance of :cpp:class:`~mdds::packed_trie_map` and restore
the state back from the file we just created::
map_type us_presidents_loaded;
std::ifstream infile("us-presidents.bin", std::ios::binary);
us_presidents_loaded.load_state<us_president_serializer>(infile);
Once again, aside from explicitly specifying the serializer type as the template
argument to the :cpp:func:`~mdds::packed_trie_map::load_state` method, it is
identical to the way we did in the previous example.
Let's compare the new instance with the old one to see if the two are equal::
cout << "Equal to the original? " << std::boolalpha << (us_presidents == us_presidents_loaded) << endl;
The output says:
.. code-block:: none
Equal to the original? true
They are. While we are at it, let's run a simple prefix search to find out
all the US presidents whose first name is 'John'::
cout << "Presidents whose first name is 'John':" << endl;
auto results = us_presidents_loaded.prefix_search("John");
for (const auto& entry : results)
cout << " * " << entry.first << " (" << entry.second.year << "; " << entry.second.party << ")" << endl;
Here is the output:
.. code-block:: none
Presidents whose first name is 'John':
* John Adams (1797; Federalist)
* John F. Kennedy (1961; Democratic)
* John Quincy Adams (1825; Democratic Republican)
* John Tyler (1841; Whig)
This looks like the correct results!
