Class DataChangeEvent

java.lang.Object
  java.util.EventObject
      jview.DataChangeEvent

All Implemented Interfaces:

Serializable

public class DataChangeEvent
extends EventObject

Signlas that the data observed by a listener has changed. The most natural choice of such a listener is a fast-reacting data analyser. This event is generated normally at user interaction, i.e. by zooming or deleting some points. Thus, different types can be distinguished for adding, deleting or re-loading of the entire data set.
