EventListenerProxy

Summary: Ctors | Methods | Inherited Methods

public abstract class EventListenerProxy
extends Object implements EventListener

An abstract wrapper class for an EventListener class which associates a set of additional parameters with the listener. Subclasses must provide the storage and accessor methods for the additional arguments or parameters.

For example, a bean which supports named properties would have a two argument method signature for adding a PropertyChangeListener for a property:

 public void addPropertyChangeListener(String propertyName,
                                       PropertyChangeListener listener)

If the bean also implemented the zero argument get listener method:

 public PropertyChangeListener[] getPropertyChangeListeners()

then the array may contain inner PropertyChangeListeners which are also PropertyChangeListenerProxy objects.

If the calling method is interested in retrieving the named property then it would have to test the element to see if it is a proxy class.

Summary

Public constructors
`EventListenerProxy(T listener)` Creates a proxy for the specified listener.

Public methods
`T`	`getListener()` Returns the listener associated with the proxy.

Inherited methods

From class java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long timeoutMillis, int nanos)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait(long timeoutMillis)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait()` Causes the current thread to wait until it is awakened, typically by being notified or interrupted.
