Pi fdZddlmZddlmZmZmZddgZGddZGddZ dS) 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: ```python >>> 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: ```python >>> 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: ```python >>> d.dispatch(Event(foo='bar', data='yours', used_by='the event handlers')) ``` ) annotations)AnyDictOptionalEvent DispatcherceZdZdZdZdZdS)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 :|j|dSN)__dict__update)selfkws a/home/jaya/work/projects/VOICE-AGENT/VIET/agent-env/lib/python3.11/site-packages/rdflib/events.py__init__zEvent.__init__7s R     cnt|j}dd|DdS)Nzz"Event.__repr__..<s-?-?-?Aa-?-?-?r>)sortedr keys)rattrss r__repr__zEvent.__repr__:s<t}))++,,-?-?-?-?-?-?-?AArN)__name__ __module__ __qualname____doc__rrrrrrr*sA  !!!BBBBBrc<eZdZUdZdZded<d dZdZd Zd Z dS) rz] An object that can dispatch events to a privately managed group of subscribers.
