ResourceEventNotifier (Silverpeas Core 6.4 API)

All Known Implementing Classes:

AttachmentEventNotifier, AttendeeLifeCycleEventNotifier, CalendarEventLifeCycleEventNotifier, CalendarEventOccurrenceLifeCycleEventNotifier, CalendarLifeCycleEventNotifier, CDIResourceEventNotifier, CommentEventNotifier, ComponentInstanceEventNotifier, GroupEventNotifier, GroupUserLinkEventNotifier, JMSResourceEventNotifier, NodeEventNotifier, PublicationEventNotifier, RelationShipEventNotifier, ReplacementEventNotifier, SpaceEventNotifier, UserEventNotifier, UserPreferenceEventNotifier, WysiwygEventNotifier
```
public interface ResourceEventNotifier<R extends Serializable,T extends ResourceEvent<?>>
```
A notifier of an event about a resource in Silverpeas. A notification can be performed either within or off the Silverpeas runtime context. According to the need, the implementation will be different and as such an abstract class is defined for each of these two different notification ways:
- org.silverpeas.core.notification.system.CDIResourceEventNotifier for a notification within the runtime context of Silverpeas; this notification is based upon the CDI Event mechanism and as such it is by default synchronous.
- org.silverpeas.core.notification.system.JMSResourceEventNotifier for a notification off the runtime context of Silverpeas; it uses a JMS backend and as such it is naturally asynchronous.
