-/**
- * @class Defines the interface and base operation of items that that can be

- * the event handlers for startDrag, onDrag, onDragOver, onDragOut.
- * Up to three html elements can be associated with a DragDrop instance:
- * <ul>
- * <li>linked element: the element that is passed into the constructor.
- * This is the element which defines the boundaries for interaction with
- * other DragDrop objects.</li>
- * <li>handle element(s): The drag operation only occurs if the element that
- * was clicked matches a handle element. By default this is the linked
- * element, but there are times that you will want only a portion of the
- * linked element to initiate the drag operation, and the setHandleElId()
- * method provides a way to define this.</li>
- * <li>drag element: this represents an the element that would be moved along
- * with the cursor during a drag operation. By default, this is the linked
- * element itself as in {@link YAHOO.util.DD}. setDragElId() lets you define
- * a separate element that would be moved, as in {@link YAHOO.util.DDProxy}
- * </li>
- * </ul>
- * This class should not be instantiated until the onload event to ensure that
- * the associated elements are available.
- * The following would define a DragDrop obj that would interact with any
- * other * DragDrop obj in the "group1" group:
- * <pre>
- * dd = new YAHOO.util.DragDrop("div1", "group1");
- * </pre>
