    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.
    1.53 - *
