public interface DeltaCollection<T>
extends Collection<T>

A delta collection unifies the modification methods add/addAll/remove/removeAll/clear into a single delta(Collection, Collection) method. This is very useful as a base for observable collections because any modification can be accomplished using a single method call which then only needs to fire a single CollectionChangedEvent.
