Method Detail

post

void post(EventDispatchContext<E,P,C,H,S> context,
          InferenceContext<E,P,C,K,H,S> inferenceContext,
          AbstractEventBus.Handle<E,P,C,K>... events)

Posts event for handling.

Parameters:

context - Event dispatching context.

events - Events to handle. An event to handle if there is one event. A tuple of joined events to handle otherwise.

getRegistrationKeys

Set<K> getRegistrationKeys()

Returns:

set of registration keys. Shared join event handler can have more than one registration key. When the set becomes empty the handler shall be removed from the inference network. Join event handlers shall cascade remove(K) to target handlers.

getHandler

EventHandler<E,P,C,H,S> getHandler()

takeSnapshot

void takeSnapshot(AbstractEventBus.Snapshot<E,P,C,K,H,S> snapshot,
                  Set<K> taken)

getPredicate

 getPredicate()

Predicate which was used during registration.

Specified by:

getPredicate in interface EventHandlerBase<E,P extends Comparable<P>,C>

Returns:
