Constructor Detail

• EventSetDescriptor

  public EventSetDescriptor(Class<?> sourceClass,
                    String eventSetName,
                    Class<?> listenerType,
                    String listenerMethodName)
                     throws IntrospectionException

  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.

  Parameters:

  sourceClass - The class firing the event.

  eventSetName - The programmatic name of the event. E.g. "fred". Note that this should normally start with a lower-case character.

  listenerType - The target interface that events will get delivered to.

  listenerMethodName - The method that will get called when the event gets delivered to its target listener interface.

  Throws:

  IntrospectionException - if an exception occurs during introspection.
