  Constructor	Description
  EventSetDescriptor​(Class<?> sourceClass, String eventSetName, Class<?> listenerType, String listenerMethodName)	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)	Creates an EventSetDescriptor from scratch using string names.
  EventSetDescriptor​(Class<?> sourceClass, String eventSetName, Class<?> listenerType, String[] listenerMethodNames, String addListenerMethodName, String removeListenerMethodName, String getListenerMethodName)	This constructor creates an EventSetDescriptor from scratch using string names.
  EventSetDescriptor​(String eventSetName, Class<?> listenerType, MethodDescriptor[] listenerMethodDescriptors, Method addListenerMethod, Method removeListenerMethod)	Creates an EventSetDescriptor from scratch using java.lang.reflect.MethodDescriptor and java.lang.Class objects.
  EventSetDescriptor​(String eventSetName, Class<?> listenerType, Method[] listenerMethods, Method addListenerMethod, Method removeListenerMethod)	Creates an EventSetDescriptor from scratch using java.lang.reflect.Method and java.lang.Class objects.
  EventSetDescriptor​(String eventSetName, Class<?> listenerType, Method[] listenerMethods, Method addListenerMethod, Method removeListenerMethod, Method getListenerMethod)	This constructor creates an EventSetDescriptor from scratch using java.lang.reflect.Method and java.lang.Class objects.

• Constructor Details

  • EventSetDescriptor

    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.

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

    listenerMethodNames - The names of the methods that will get called when the event gets delivered to its target listener interface.

    addListenerMethodName - The name of the method on the event source that can be used to register an event listener object.

    removeListenerMethodName - The name of the method on the event source that can be used to de-register an event listener object.

    Throws:

    IntrospectionException - if an exception occurs during introspection.

  • EventSetDescriptor

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

    listenerMethodNames - The names of the methods that will get called when the event gets delivered to its target listener interface.

    addListenerMethodName - The name of the method on the event source that can be used to register an event listener object.

    removeListenerMethodName - The name of the method on the event source that can be used to de-register an event listener object.

    getListenerMethodName - The method on the event source that can be used to access the array of event listener objects.

    Throws:

    IntrospectionException - if an exception occurs during introspection.
