Type Parameters:

EVENT -

RESULT -

All Superinterfaces:

EventProducer<EVENT,RESULT>, Serializable

All Known Implementing Classes:

EventManagerImpl

public interface EventManager<EVENT,RESULT>
extends EventProducer<EVENT,RESULT>

The EventManager is the central control unit within a client class which want to fire events. It holds references to an EventListenerRegistration as well as to a EventManagerConnector.

The fireEvent(Object) method will pick up given events and will take care of the event handling. This includes the management of connected EventListener as well as a chaining path via the EventManagerConnector.

Additionally with the EventProducer interface clients can make themselves usable for EventHandler instances which delegates the control to a central EventHandler.
