+/**
+ * An abstract adapter class for receiving container events.
+ * The methods in this class are empty. This class exists as
+ * convenience for creating listener objects.
+ * <P>
+ * Extend this class to create a <code>ContainerEvent</code> listener
+ * and override the methods for the events of interest. (If you implement the
+ * <code>ContainerListener</code> interface, you have to define all of
+ * the methods in it. This abstract class defines null methods for them
+ * all, so you can only have to define methods for events you care about.)
+ * <P>
+ * Create a listener object using the extended class and then register it with
+ * a component using the component's <code>addContainerListener</code>
+ * method. When the container's contents change because a component has
+ * been added or removed, the relevant method in the listener object is invoked,
+ * and the <code>ContainerEvent</code> is passed to it.
+ *
