:mod:`notify` - Simple notification system
|
||
|
|
==========================================
|

|
|
|

|
|
.. module:: notify
|
||
|
|
|
||
|
|
This module is a brain-dead simple notification system involving a :class:`Broadcaster` and a :class:`Listener`. A listener can only listen to one broadcaster. A broadcaster can have multiple listeners. If the listener is connected, whenever the broadcaster calls :meth:`~Broadcaster.notify`, the method with the same name as the broadcasted message is called on the listener.
|
||
|
|
|
||
|
|
.. class:: Broadcaster
|
||
|
|
|
||
|
|
.. method:: notify(msg)
|
||
|
|
|
||
|
|
Notify all connected listeners of ``msg``. That means that each listeners will have their method with the same name as ``msg`` called.
|
||
|
|
|
||
|
|
.. class:: Listener(broadcaster)
|
||
|
|
|
||
|
|
A listener is initialized with the broadcaster it's going to listen to. Initially, it is not connected.
|
||
|
|
|
||
|
|
.. method:: connect()
|
||
|
|
|
||
|
|
Connects the listener to its broadcaster.
|
||
|
|
|
||
|
|
.. method:: disconnect()
|
||
|
|
|
||
|
|
Disconnects the listener from its broadcaster.
