public interface ObserverDescriptor<E extends GenericEvent<?>,O extends Observer<E>,EM extends EventMatcher<E>> extends Observer<E>
This ObserverDescriptor describes the Observer, i.e. in some cases an Observer requires an EventMatcher which determines which GenericActionEvent instances to pass to the Observer. The ObserverDescriptor is itself an Observer calling the EventMatcher to determine whether to delegate the GenericActionEvent to contained Observer or not.
