internalTrigger

public void internalTrigger(NodeInstance from,
                            String type)

Overrides:

internalTrigger in class ExtendedNodeInstanceImpl

createTimerInstance

protected TimerInstance createTimerInstance(Timer timer)

signalEvent

public void signalEvent(String type,
                        Object event)

Description copied from interface: EventListener

Signals that an event has occurred. The type parameter defines which type of event and the event parameter can contain additional information related to the event.

Specified by:

signalEvent in interface EventListener

Parameters:

type - the type of event

event - the data associated with this event

getEventTypes

public String[] getEventTypes()

Description copied from interface: EventListener

Returns the event types this event listener is interested in. May return null if the event types are unknown.

Specified by:

getEventTypes in interface EventListener

triggerCompleted

public void triggerCompleted()

addEventListeners

public void addEventListeners()

Specified by:

addEventListeners in interface EventBasedNodeInstanceInterface

addTimerListener

protected void addTimerListener()

removeEventListeners

public void removeEventListeners()

Specified by:

removeEventListeners in interface EventBasedNodeInstanceInterface

triggerCompleted

                                boolean remove)

Overrides:

triggerCompleted in class ExtendedNodeInstanceImpl

getTimerInstances

public List<Long> getTimerInstances()

internalSetTimerInstances
