public class TriggerEvent

extends RTEvent

Generic event used to trigger one-shot activities in an event-driven fashion. Some timer thread is useful to generate a single triggering event. For cyclic or periodic events, the class PeriodicEvent is to be used for the periodic events.

A TriggerEvent has no owner. That is, owner is set to null, enabling the event to be sent over and over again from the same source. Subclasses are, however, free to assign ownership simply by assigning the (protected) owner field.
