public class DataValueChangeEvent

extends EventObject

DataValueChangeEvent is inherited from EventObject, and holds a DataHolder object as an event source.

A DataValueChangeEvent occurs if the data value or information related to it is updated by the setValue method of the DataHolder object. The event object holds a reference to the value and related information of the DataHolder object at the time when the event occurs.

It is possible for the information maintained by the DataHolder object, that is the event source, to be updated in the period in between when the event occurs and the beginning of processing by the listener begins. If the most current information after the event occurs is needed by the listener, those values can be acquired from the DataHolder object held as the event source.
