4Ysh \dZddgZGddeZGddeZdZedk(reyy)a 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) # doctest: +ELLIPSIS 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')) Event DispatcherceZdZdZdZdZy)ra An event is a container for attributes. The source of an event creates this object, or a subclass, gives it any kind of data that the events handlers need to handle the event, and then calls notify(event). The target of an event registers a function to handle the event it is interested with subscribe(). When a sources calls notify(event), each subscriber to that event will be called in no particular order. c :|jj|yN)__dict__update)selfkws m/var/www/sten-cake5-migrate2.hellocrow.space/lexinfo-master/env/lib/python3.12/site-packages/rdflib/events.py__init__zEvent.__init__*s R czt|jj}d|Dcgc]}|c}dScc}w)Nz)sortedrkeys)r attrsas r __repr__zEvent.__repr__-s0t}}))+,9>-?Aa-?AA-?s 8N)__name__ __module__ __qualname____doc__r rr r rrs !Br c,eZdZdZdZdZdZdZdZy)rz] An object that can dispatch events to a privately managed group of subscribers.
