Action Details
emit(UUID,Event,Scope<T>) 
def emit(UUID,Event,Scope<T>)
emitLocally(Event,Scope<T>) 
protected def emitLocally(Event,Scope<T>)
Do the emission of the event.

This function emits the event only on the internal event bus of the listeners.

This function launch a task for each matching listener.
Parameters:
event - the event to emit.
scope - description of the scope of the event, i.e. the receivers of the event.
ensureEventSource(UUID,Event) 
protected def ensureEventSource(UUID,Event)
Ensure that the given event has a source.
Parameters:
eventSource - the source of the event.
event - the event to emit.

def getNumberOfWeakParticipants : int
getScopedParticipants(Scope<T>) 
def getScopedParticipants(Scope<T>) : java.util.concurrent.ConcurrentLinkedDeque<E>
Replies the participants that matches the given scope.
Parameters:
scope - the scope.
Returns:
the matching participants.
getSpaceParticipantListener 
def getSpaceParticipantListener : SpaceParticipantListener
isPseudoEmpty(UUID) 
def isPseudoEmpty(UUID) : boolean
registerToSpace(EventListener,boolean) 
protected def registerToSpace(EventListener,boolean) : Address
Register the specified entity on this space
Parameters:
entity - - the entity to be registered
weakParticipant - - boolean specifying if the specified entity may prevent the space from the destruction if it is the only remaining entity within this space. A Weak participant will not prevent the space from begin destroyed if it is the only one staying in it, a Strong participant will prevent it. A space containing only Weak participants will be destroyed by the SRE Kernel
setEventTransportService(EventTransportService) 
def setEventTransportService(EventTransportService)
Set the event router.
Parameters:
router - the router.
