o di@s,dZddlZdgZiZdddZddZdS) aClass-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): ... pass >>> def handler1(event): ... print("handler1 %r" % event.__class__.__name__) >>> zope.event.classhandler.handler(MyEvent, handler1) Descriptor syntax: >>> @zope.event.classhandler.handler(MyEvent) ... def handler2(event): ... print("handler2 %r" % event.__class__.__name__) >>> class MySubEvent(MyEvent): ... pass >>> @zope.event.classhandler.handler(MySubEvent) ... def handler3(event): ... print("handler3 %r" % event.__class__.__name__) 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' NhandlerFcsT|dur fddStstjjttvr|gt<nt||r(tSdS)z Define an event handler for a (new-style) class. This can be called with a class and a handler, or with just a class and the result used as a handler decorator.
