public class PropertyChangeEventJAI

extends PropertyChangeEvent

A class instances of which represent Java Bean-style events emitted by JAI objects. This class definition adds no functionality to that provided by the superclass. The significance of the derivation is that bean events will be easily identifiable as having been generated by JAI classes by virtue of their being instances of this event class. Note that this does not prevent JAI properties from colliding with other Java Bean properties in the Bean property name space.

Since:

JAI 1.1
