/**
 * Marks a method as an event handler, as used by
 * {@link AnnotatedHandlerFinder} and {@link EventBus}.
 *
 * 

The type of event will be indicated by the method's first (and only) * parameter. If this annotation is applied to methods with zero parameters, * or more than one parameter, the object containing the method will not be able * to register for event delivery from the {@link EventBus}. * *

Unless also annotated with @{@link AllowConcurrentEvents}, event handler * methods will be invoked serially by each event bus that they are registered * with. * * @author Cliff Biffle * @since 10.0 */ @Retention(RetentionPolicy.RUNTIME) @Target(ElementType.METHOD) @Beta public @interface Subscribe { }
