org.eclipse.persistence.descriptors.DescriptorEvent
public class DescriptorEvent
Purpose: Encapsulate the information provided with descriptor events. This is used as the argument to any event raised by the descriptor. Events can be registered for through two methods, the first is by providing a method to be called on the object that a particular operation is being performed on. The second is by registering a manager object to be notified when any event occurs for that descriptor. The second method is more similar to the java beans event model but requires the registered object to implement the DescriptorEventListener interface.
