Evented classes are classes which use an EventEmitter to call instance methods during runtime. To achieve this without this helper, you would instantiate an `EventEmitter` in the `__init__` method and then call `event_emitter.on` for every method on `self`. This decorator and the `on` function help make things look a little nicer by defining the event handler on the method in the class and then adding the `__init__` hook in a wrapper: ```py from pyee.cls import evented, on @evented class Evented: @on("event") def event_handler(self, *args, **kwargs): print(self, args, kwargs) evented_obj = Evented() evented_obj.event_emitter.emit( "event", "hello world", numbers=[1, 2, 3] ) ``` The `__init__` wrapper will create a `self.event_emitter: EventEmitter` automatically but you can also define your own event_emitter inside your class's unwrapped `__init__` method. For example, to use this decorator with a `TwistedEventEmitter`:: ```py @evented class Evented: def __init__(self): self.event_emitter = TwistedEventEmitter() @on("event") async def event_handler(self, *args, **kwargs): await self.some_async_action(*args, **kwargs) ``` c|g|Ri|t|dst|_D]5}|j|jt ||j6dS)N event_emitter)hasattrr r7r,r r2r)rr/r0hhandlersog_inits rinitzevented..initis&t&&&v&&&t_-- 0!-D  B BA   ! !!'5qx+@+@ A A A A B Br)listrr'rr)r4r<r:r;s @@reventedr>7spZ#9ooH OO G 3<BBBBBBCL JrN) dataclassesr functoolsrtypingrrrr pyeer r rrrr,r2r3r>rrrrCsG!!!!!!000000000000           HJJ  c hz834    ge4   ========r
