OortList.DeltaListener (CometD :: Java 4.0.9 API)

java.lang.Object
- org.cometd.oort.OortList.DeltaListener<E>

Type Parameters:

E - the element type

All Implemented Interfaces:

EventListener, OortObject.Listener<List<E>>

Enclosing class:

OortList<E>
```
public static class OortList.DeltaListener<E>
extends Object
implements OortObject.Listener<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.
