-Dirt Simple Events
-
-A Dispatcher (or a subclass of Dispatcher) stores event handlers that
-are 'fired' simple event objects when interesting things happen.
-
-Create a dispatcher:
-
- >>> d = Dispatcher()
-
-Now create a handler for the event and subscribe it to the dispatcher
-to handle Event events. A handler is a simple function or method that
-accepts the event as an argument:
-
- >>> def handler1(event): print(repr(event))
- >>> d.subscribe(Event, handler1)
-
-Now dispatch a new event into the dispatcher, and see handler1 get
-fired:
-
- >>> d.dispatch(Event(foo='bar', data='yours', used_by='the event handlers'))
- <rdflib.events.Event ['data', 'foo', 'used_by']>
