@Contract @ConstrainedTo(value=SERVER) public interface ApplicationEventListener
application events. The implementation of this interface will be called for two kind of events: application events and
request events. This interface will listen to all
application event typesbut only to first request event which is the
RequestEvent.Type.START. On this event the application event listener can decide whether it will listen to the request and return
request event listenerfor listening to further request events. } The implementation of this interface can be registered as a standard Jersey/JAX-RS provider by annotating with
@Providerannotation in the case of class path scanning, by registering as a provider using
ResourceConfigor by returning from
Application.getSingletons()}. The provider can be registered only on the server side. Application event listener can read data of events but must not modify them in any way. The implementation must be thread safe (the methods might be called from different threads).
void onEvent(ApplicationEvent event)
event. This method is called when new event occurs.
event- Application event.
RequestEventListener onRequest(RequestEvent requestEvent)
request event listenerif listening to
request eventsis required. The method is called once for each new incoming request. If listening to the request is required then request event must be returned from the method. Such a request event listener will receive all request events that one request. If listening to request event for the request is not required then
nullmust be returned from the method (do not return empty mock listener in these cases as it will have negative performance impact).
requestEvent- Event of type
requestEvent; null otherwise.
