(��V�������������������@���s&���d�Z�ddlZi�Zddd�Zdd��ZdS�)	a���Class-based event handlers

A light-weight event-handler framework based on event classes.

Handlers are registered for event classes:

>>> import zope.event.classhandler

>>> class MyEvent(object):
    ...     def __repr__(self):
    ...         return self.__class__.__name__

>>> def handler1(event):
    ...     print("handler1 %r" % event)

>>> zope.event.classhandler.handler(MyEvent, handler1)

Descriptor syntax:

>>> @zope.event.classhandler.handler(MyEvent)
    ... def handler2(event):
    ...     print("handler2 %r" % event)

>>> class MySubEvent(MyEvent):
    ...     pass

>>> @zope.event.classhandler.handler(MySubEvent)
    ... def handler3(event):
    ...     print("handler3 %r" % event)

Subscribers are called in class method-resolution order, so only
new-style event classes are supported, and then by order of registry.

>>> import zope.event
    >>> zope.event.notify(MySubEvent())
    handler3 MySubEvent
    handler1 MySubEvent
    handler2 MySubEvent

This can be called with a class and a handler, or with just a
