Inversion-of-control versions of on. Tell this object to listen to
an event in another object... keeping track of what it's listening to
for easier unbinding later.
Optional callback: EventCallbackOptional priority: numberInversion-of-control versions of once.
Optional priority: numberRemove one or many callbacks. If context is null, removes all
callbacks with that function. If callback is null, removes all
callbacks for the event. If name is null, removes all bound
callbacks for all events.
Optional context: anyOptional callback: EventCallbackOptional context: anyBind an event to a callback function. Passing "all" will bind
the callback to all events fired.
Optional context: anyOptional callback: EventCallbackOptional context: anyOptional priority: numberOptional context: anyOptional priority: numberBind an event to only be triggered a single time. After the first time the callback is invoked, its listener will be removed. If multiple events are passed in using the space-separated syntax, the handler will fire once for each event, not once for a combination of all events.
Optional context: anyOptional context: anyOptional priority: anyTell this object to stop listening to either specific events ... or to every object it's currently listening to.
Optional obj: EventDispatcherOptional name: string | EventMapOptional callback: EventCallbackTrigger one or many events, firing all bound callbacks. Callbacks are
passed the same arguments as trigger is, apart from the event name
(unless you're listening on "all", which will cause your callback to
receive the true name of the event as the first argument).
A class that provides a custom event channel.
