|
|
// a (Array) | A Boolean flag indicating whether the cell's formula
|
|
// | is an array formula. True if this cell's formula is
|
|
// | an array formula, false otherwise. If there is a
|
|
// | conflict between this attribute and the t attribute
|
|
// | of the f element (§18.3.1.40), the t attribute takes
|
|
// | precedence. The possible values for this attribute
|
|
// | are defined by the W3C XML Schema boolean datatype.
|
|
// |
|
|
// i (Sheet Id) | A sheet Id of a sheet the cell belongs to. If this is
|
|
// | omitted, it is assumed to be the same as the i value
|
|
// | of the previous cell.The possible values for this
|
|
// | attribute are defined by the W3C XML Schema int datatype.
|
|
// |
|
|
// l (New Dependency Level) | A Boolean flag indicating that the cell's formula
|
|
// | starts a new dependency level. True if the formula
|
|
// | starts a new dependency level, false otherwise.
|
|
// | Starting a new dependency level means that all
|
|
// | concurrent calculations, and child calculations, shall
|
|
// | be completed - and the cells have new values - before
|
|
// | the calc chain can continue. In other words, this
|
|
// | dependency level might depend on levels that came before
|
|
// | it, and any later dependency levels might depend on
|
|
// | this level; but not later dependency levels can have
|
|
// | any calculations started until this dependency level
|
|
// | completes.The possible values for this attribute are
|
|
// | defined by the W3C XML Schema boolean datatype.
|
|
// |
|
|
// r (Cell Reference) | An A-1 style reference to a cell.The possible values
|
|
// | for this attribute are defined by the ST_CellRef
|
|
// | simple type (§18.18.7).
|
|
// |
|
|
// s (Child Chain) | A Boolean flag indicating whether the cell's formula
|
|
// | is on a child chain. True if this cell is part of a
|
|
// | child chain, false otherwise. If this is omitted, it
|
|
// | is assumed to be the same as the s value of the
|
|
// | previous cell .A child chain is a list of calculations
|
|
// | that occur which depend on the parent to the chain.
|
|
// | There shall not be cross dependencies between child
|
|
// | chains. Child chains are not the same as dependency
|
|
// | levels - a child chain and its parent are all on the
|
|
// | same dependency level. Child chains are series of
|
|
// | calculations that can be independently farmed out to
|
|
// | other threads or processors.The possible values for
|
|
// | this attribute is defined by the W3C XML Schema
|
|
// | boolean datatype.
|
|
// |
|
|
// t (New Thread) | A Boolean flag indicating whether the cell's formula
|
|
// | starts a new thread. True if the cell's formula starts
|
|
// | a new thread, false otherwise.The possible values for
|
|
// | this attribute is defined by the W3C XML Schema
|
|
// | boolean datatype.
