Examples of DescriptorEventListener

oracle.toplink.essentials.descriptors.DescriptorEventListener

Purpose: Used to support Java event listener event model on descriptors. Events can be registered for, through two methods, the first is by providing a method to be called on the object that a paticualr operation is being performed on. The second is by registering an event listener object to be notified when any event occurs for that descriptor. The second method is more similar to the java beans event model and requires the registered listener to implement the DescriptorEventListener interface. @see DescriptorEventAdapter @see DescriptorEventManager @see DescriptorEvent
