public abstract class CDIResourceEventNotifier<R extends Serializable,T extends AbstractResourceEvent>
extends Object
implements ResourceEventNotifier<R,T>

A synchronous event notifier using the notification bus of CDI. This bus is based on the Observer pattern but by using the annotations in place of code lines to setup listeners and so on. All synchronous notifiers should extend this class; they have just to implement the createResourceEventFrom method, the notification itself is performed by this abstract class.
