/**
 * <p>
 * Indicates that the marked method should be called when an attached set is
 * modified.
 *
 * <p>
 * The method can have any name, but should take a single parameter which is
 * either a {@link SetModifiedEvent} or any superclass. Otherwise, an
 * {@link IllegalArgumentException} will be thrown by
 * {@link PojoCache#addListener(java.lang.Object)}
 *
 * <p>
 * Example:
 *
 * <pre>
 *    &#064PojoCacheSetener
 *    public class MySetener()
 *    {
 *       &#064SetModified
 *       public void handleModified(SetModifiedEvent event)
 *       {
 *          System.out.println(&quot;Set = &quot; + even.getSource());
 *       }
 *    }
 * </pre>
