public static class OortList.DeltaListener<E>
extends java.lang.Object
implements OortObject.Listener<java.util.List<E>>

An implementation of OortObject.Listener that converts whole list events into OortList.ElementListener events.

For example, if an entity list:

 [A, B]

is replaced by a list:

 [A, C, D]

then this listener generates two "add" events for C and D and one "remove" event for B.
