0N/A/**
0N/A * An abstract adapter class for receiving container events.
0N/A * The methods in this class are empty. This class exists as
0N/A * convenience for creating listener objects.
0N/A * <P>
0N/A * Extend this class to create a <code>ContainerEvent</code> listener
0N/A * and override the methods for the events of interest. (If you implement the
0N/A * <code>ContainerListener</code> interface, you have to define all of
0N/A * the methods in it. This abstract class defines null methods for them
0N/A * all, so you can only have to define methods for events you care about.)
0N/A * <P>
0N/A * Create a listener object using the extended class and then register it with
0N/A * a component using the component's <code>addContainerListener</code>
0N/A * method. When the container's contents change because a component has
0N/A * been added or removed, the relevant method in the listener object is invoked,
0N/A * and the <code>ContainerEvent</code> is passed to it.
