Interface EventHandler<EVENT,RESULT>

public interface EventHandler<EVENT,RESULT>

Declares the consumer of events.
Subclasses will get references to EventProducer instances and will register their EventListener to these. This gives the control to the EventHandler at holding the references to the EventProducer, too. The EventHandler can so decide to unregister at any given time.
Since the EventHandler is often used to hold controlling business logic this kind of component referencing will better reflect the logic requirements.
