/**
 * An abstract adapter class for receiving drag source events. The methods in
 * this class are empty. This class exists only as a convenience for creating
 * listener objects.
 * <p>
 * Extend this class to create a <code>DragSourceEvent</code> listener
 * and override the methods for the events of interest. (If you implement the
 * <code>DragSourceListener</code> interface, you have to define all of
 * the methods in it. This abstract class defines null methods for them
 * all, so you 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 <code>DragSource</code>. When the drag enters, moves over, or exits
 * a drop site, when the drop action changes, and when the drag ends, the
 * relevant method in the listener object is invoked, and the
 * <code>DragSourceEvent</code> is passed to it.
 * <p>
 * The drop site is <i>associated with the previous <code>dragEnter()</code>
 * invocation</i> if the latest invocation of <code>dragEnter()</code> on this
 * adapter corresponds to that drop site and is not followed by a
 * <code>dragExit()</code> invocation on this adapter.
 *
 * @see DragSourceEvent
 * @see DragSourceListener
 * @see DragSourceMotionListener
