Javadoc
Signals the engine 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. All process instances that are listening to this type
of (external) event will be notified. For performance reasons, this type of event
signaling should only be used if one process instance should be able to notify
other process instances. For internal event within one process instance, use the
signalEvent method that also include the processInstanceId of the process instance
in question.
