Examples of java.beans.EventSetDescriptor

java.beans.EventSetDescriptor
An EventSetDescriptor describes a group of events that a given Java bean fires.
The given group of events are all delivered as method calls on a single event listener interface, and an event listener object can be registered via a call on a registration method supplied by the event source.
