All Implemented Interfaces:

EventDispatcher<E,R>

public class SimpleDispatcher<E extends Event,R extends ListenerRegistry<? extends Listener>>
extends Object
implements EventDispatcher<E,R>

This is a 'general purpose' EventDispatcher. Blocking Listeners are invoked in the same order they are returned from ListenerRegistry. All non-blocking Listeners are executed in parallel. Threads are pooled temporarily, after a period of inactivity idle threads are automatically reclaimed. Override dispatchBlocking() and dispatchNonBlocking() to override dispatching mechods
