Interface ListenerRegistry<L extends Listener>

public interface ListenerRegistry<L extends Listener>

This interface represents a registry where Listeners can be registered to be invoked. ListenerRegsitry is injected into an EventDispatcher. Dispatcher eventually invokes Listeners discovering them through getListeners(). Listeners are registered in two modes, blocking and non-blocking. These modes for the consumption of EventDispatcher. For a discussion of blocking and non-blocking modes, please see EventDispatcher.
