Class PropertyChangeEvent

java.lang.Object
  java.util.EventObject
      org.eclipse.jpt.common.utility.model.event.ChangeEvent
          org.eclipse.jpt.common.utility.model.event.PropertyChangeEvent

All Implemented Interfaces:

Serializable

public final class PropertyChangeEvent
extends ChangeEvent

A "property change" event gets delivered whenever a model changes a "bound" or "constrained" property. A PropertyChangeEvent is sent as an argument to the PropertyChangeListener. A PropertyChangeEvent is accompanied by the old and new values of the property.

Provisional API: This class is part of an interim API that is still under development and expected to change significantly before reaching stability. It is available at this early stage to solicit feedback from pioneering adopters on the understanding that any code that uses this API will almost certainly be broken (repeatedly) as the API evolves.
