1.31 -/**
1.32 - * An abstract wrapper class for an {@code EventListener} class
1.33 - * which associates a set of additional parameters with the listener.
1.34 - * Subclasses must provide the storage and accessor methods
1.35 - * for the additional arguments or parameters.
1.36 - * <p>
1.37 - * For example, a bean which supports named properties
1.38 - * would have a two argument method signature for adding
1.39 - * a {@code PropertyChangeListener} for a property:
1.40 - * <pre>
1.41 - * public void addPropertyChangeListener(String propertyName,
1.42 - * PropertyChangeListener listener)
1.43 - * </pre>
1.44 - * If the bean also implemented the zero argument get listener method:
1.45 - * <pre>
1.46 - * public PropertyChangeListener[] getPropertyChangeListeners()
1.47 - * </pre>
1.48 - * then the array may contain inner {@code PropertyChangeListeners}
1.49 - * which are also {@code PropertyChangeListenerProxy} objects.
1.50 - * <p>
1.51 - * If the calling method is interested in retrieving the named property
1.52 - * then it would have to test the element to see if it is a proxy class.
