All Known Implementing Classes:
FrameworkSettings
Functional Interface:
This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
@FunctionalInterface public interface IEventDispatcher
Delivers an event to a component. Developers can implement and register their dispatchers in FrameworkSettings to create custom strategies for how events get delivered to components

      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.
