- * This abstract class provides the infrastructure needed to wrap
- * a tree value model, "lazily" listen to it, and convert
- * its change notifications into property value model change
- * notifications.
- * <p>
- * Subclasses must override:<ul>
- * <li>{@link #buildValue()}<p>
- *     to return the current property value, as derived from the
- *     current collection value
- * </ul>
- * Subclasses might want to override the following methods
- * to improve performance (by not recalculating the value, if possible):<ul>
- * <li>{@link #nodeAdded(TreeChangeEvent event)}
- * <li>{@link #nodeRemoved(TreeChangeEvent event)}
- * <li>{@link #treeCleared(TreeChangeEvent event)}
- * <li>{@link #treeChanged(TreeChangeEvent event)}
