Class EditChangeEvent

java.lang.Object

oracle.spatial.network.nfe.vis.maps.model.EditChangeEvent

public class EditChangeEvent
extends java.lang.Object

Defines an edit event which can be a spatial representation change, a change in one non-spatial attribute, or a change in several non-spatial attributes at the same time. This event class is used to store the history of changes in the change manager class, and it can be used for undo operations. The change manager class handles this events, and in general the user application does not define instance of this class.
