public interface PropertyChangeListener

PropertyChangeListener describes a type of property listener that is invoked after a property change has occurred (through the WS-RP SetResourceProperties operation). Listeners can react to or report the change from the propertyChanged() method. If you want to prevent changes, you should use a PropertyChangeApprover.
