-/**
- * This abstract class provides the infrastructure needed to wrap
- * a list value model, "lazily" listen to it, and convert
- * its change notifications into property value model change
- * notifications.
- *
- * Subclasses must override:
- * - #buildValue()
- * to return the current property value, as derived from the
- * current list value
- *
- * Subclasses might want to override:
- * - #itemsAdded(ListChangeEvent event)
- * - #itemsRemoved(ListChangeEvent event)
- * - #itemsReplaced(ListChangeEvent event)
- * - #itemsMoved(ListChangeEvent event)
- * - #listCleared(ListChangeEvent event)
- * - #listChanged(ListChangeEvent event)
