Annotation Interface Event.AsyncObserver

Enclosing class:

Event

@Target({METHOD,TYPE})
public static @interface Event.AsyncObserver

A service method that is an event observer. The method MUST have a parameter that is the type of the event. Async observers are invoked on a separate thread and will never feed information back to the Event.Emitter (even if Event.Emitter.emitAsync(Object, Qualifier...) is used).
