Method Detail

dispatchEvent

void dispatchEvent(Object sink,
                   IEvent<?> event,
                   Component component)

Dispatches the even to the target component

Parameters:

sink - the sink for the event. Sinks usually implement IEventSink or IComponentAwareEventSink. See the component parameter described below.

event -

component - provides context to the sink. Some sinks are owned by the component, eg Behaviors, and thus it is useful for them to have a reference to their owning component. If this method is not null the dispatcher should try to look for an alternative sink method which takes a component reference as an additional parameter, one such implementation is IComponentAwareEventSink.
