Interface EventBusListenerMethodFilter

All Known Implementing Classes:
NoEventBusListenerMethodFilter
public interface EventBusListenerMethodFilter

A method annotated with @EventBusListenerMethod will be invoked if it is subscribed to the EventBus that published the Event (or Object payload). That method will oftentimes employ filtering code in the method internals, because of the possibility that multiple annotated methods might listen to same the Event.

As a convenience, an implementation of this filter may be defined in EventBusListenerMethod.filter() and stand in place of such filtering code.
