-/**
- * This abstract class provides the infrastructure needed to wrap
- * a collection 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 #itemsAdded(CollectionAddEvent event)}
- * <li>{@link #itemsAdded(Iterable)}
- * <li>{@link #itemsRemoved(CollectionRemoveEvent event)}
- * <li>{@link #itemsRemoved(Iterable)}
- * <li>{@link #collectionCleared(CollectionClearEvent event)}
- * <li>{@link #collectionChanged(CollectionChangeEvent event)}
- * </ul>
- * 
- * @param <V> the type of the model's value
- * @param <E> the type of the wrapped collection value model's elements
