public class RemovalAwareList
extends ManageableArrayList
implements IRemovalAwareCollection

This is a list that tracks removal and addition of elements. This tracking allow the PersistenceBroker to delete elements from the database that have been removed from the collection before a PB.store() orperation occurs. This will allow to use the PB api in way pretty close to ODMG persistent collections!
