All Implemented Interfaces:

java.io.Serializable

public class VariableServiceEvent
extends java.util.EventObject

A semantic event which indicates that an event occured on a VariableService.

This event is generated by a VariableService when a operation related to the service (such as variable value changing or variable instance name modification) occurs.

The event is passed to every VariableServiceListener object that registered to receive such events using the VariableService.addVariableServiceListener(VariableServiceListener) method.

The object that implements the VariableModelListener interface gets this VariableServiceEvent when the event occurs.
