+/**
+ * A <code>TransferDragSourceListener</code> is a <code>DragSourceListener</code>
+ * that can handle one type of SWT {@link Transfer}.
+ * The purpose of a <code>TransferDragSourceListener</code> is to:
+ * <ul>
+ *   <li>Determine enablement for a drag operation. A <code>TransferDragSourceListener</code>
+ *  will not be used in a drag operation if the <code>DragSourceEvent#doit</code> field
+ *  is set to false in <code>DragSourceListener#dragStart(DragSourceEvent)</code>.
+ *   <li>Set data for a single type of drag and <code>Transfer</code> type.
+ * </ul>
+ * <p>
+ * A <code>DelegatingDragAdapter</code> allows these functions to be implemented
+ * separately for unrelated types of drags. <code>DelegatingDragAdapter</code> then
+ * combines the function of each <code>TransferDragSourceListener</code>, while
+ * allowing them to be implemented as if they were the only <code>DragSourceListener</code>.
+ * </p>
+ * @since 3.0
