SUMMARY: INNER | FIELD | CONSTR | METHOD | DETAIL: FIELD | CONSTR | METHOD |
java.lang.Object | +--java.beans.FeatureDescriptor | +--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.

Constructor Summary | |
|
EventSetDescriptor(Class sourceClass,
String eventSetName,
Class listenerType,
String listenerMethodName)
This constructor creates an EventSetDescriptor assuming that you are following the most simple standard design pattern where a named event "fred" is (1) delivered as a call on the single method of interface FredListener, (2) has a single argument of type FredEvent, and (3) where the FredListener may be registered with a call on an addFredListener method of the source component and removed with a call on a removeFredListener method. |
|
EventSetDescriptor(Class sourceClass,
String eventSetName,
Class listenerType,
String[] listenerMethodNames,
String addListenerMethodName,
String removeListenerMethodName)
This constructor creates an EventSetDescriptor from scratch using string names. |
