Class EventEmitter::Range
An object that implements the EventEmitter API. Extending this class does nothing, its mostly to indicate intent.
The classes EventRegistration::Range and EventDispatch::Range must be extended to get a working EventEmitter model. An EventRegistration models a method call that registers some event handler on an EventEmitter. And EventDispatch models that some event is dispatched on an EventEmitter.
Both the EventRegistration and EventDispatch have a field emitter,
which is the EventEmitter that events are registered on / dispatched to respectively.
Here is a simple JavaScript example with the NodeJS EventEmitter: var e = new EventEmitter(); // <- EventEmitter e.on(“name”, (data) => {…}); // <- EventRegistration e.emit(“name”, “foo”); // <- EventDispatch
