Method Detail

publish

void publish(Object event)

Publish an event that will be consumed by all listeners which have registered to receive it. Implementations must dispatch events to listeners which have a public method annotated with EventListener and one argument which is assignable from the event type (i.e. a superclass or interface implemented by the event object). Implementations may also dispatch events to legacy EventListener implementations based on the types returned from EventListener.getHandledEventClasses(). This method should process all event listeners, despite any errors or exceptions that are generated as a result of dispatching the event.

Parameters:

event - the event to publish

Throws:

NullPointerException - if the event is null
