Class EventManagerImpl<EVENT,RESULT>

java.lang.Object
  org.omnaest.utils.events.concrete.EventManagerImpl<EVENT,RESULT>

Type Parameters:

EVENT -

RESULT -

All Implemented Interfaces:

Serializable, EventManager<EVENT,RESULT>, EventProducer<EVENT,RESULT>

public class EventManagerImpl<EVENT,RESULT>
extends Object
implements EventProducer<EVENT,RESULT>, EventManager<EVENT,RESULT>

Manager for EventListener instances which implements the EventListener interface, too. The EventListener.handleEvent(Object) is executed for all of the EventListener instances which are not null.

To add new EventListener instances use the EventListenerRegistrationImpl instance which can be retrieved via getEventListenerRegistration(). Its best practice to make this method available to clients by a delegate method.
