``gevent.hub`` - The Event Loop and the Hub
|
|
=============================================
|
|
|
|
.. module:: gevent.hub
|
|
|
|
The hub is a special greenlet created automatically to run the event loop.
|
|
|
|
The current hub can be retrieved with `get_hub`.
|
|
|
|
.. autofunction:: get_hub
|
|
|
|
|
|
.. autoclass:: Hub
|
|
:members:
|
|
|
|
.. automethod:: wait
|
|
.. automethod:: cancel_wait
|
|
|
|
.. attribute:: loop
|
|
the event loop object (`ILoop`) associated with this hub and thus
|
|
this native thread.

|
The Event Loop
|
|
==============
|
|
|
|
The current event loop can be obtained with ``get_hub().loop``.
|
|
All implementations of the loop provide a common minimum interface.
|
|
|
|
.. autointerface:: gevent._interfaces.ILoop
|
|
.. autointerface:: gevent._interfaces.IWatcher
|
|
.. autointerface:: gevent._interfaces.ICallback

|
|
|
The following exceptions *are not* expected to be thrown and *are not*
|
|
meant to be caught; if they are raised to user code it is generally a
|
|
serious programming error or a bug in gevent, greenlet, or its event
|
|
loop implementation. They are presented here for documentation
|
|
purposes only.
