    Description copied from interface: DeltaReplicatedData
    
    Reset collection of deltas from mutator operations. When the Replicator invokes the modify function of the Update message the delta is always "reset" and when the user code is invoking one or more mutator operations the data is collecting the delta of the operations and makes it available for the Replicator with the DeltaReplicatedData.delta() accessor. When the Replicator has grabbed the delta it will invoke this method to get a clean data instance without the delta.
    
    Specified by:
    
    resetDelta in interface DeltaReplicatedData
  - delta
```
public scala.Option<ORMap.DeltaOp> delta()
```
    Description copied from interface: DeltaReplicatedData
    
    The accumulated delta of mutator operations since previous DeltaReplicatedData.resetDelta(). When the Replicator invokes the modify function of the Update message and the user code is invoking one or more mutator operations the data is collecting the delta of the operations and makes it available for the Replicator with the DeltaReplicatedData.delta() accessor. The modify function shall still return the full state in the same way as ReplicatedData without support for deltas.

```

    Description copied from interface: RemovedNodePruning
    
    The nodes that have changed the state for this data and would need pruning when such node is no longer part of the cluster.

```
public boolean needPruningFrom(UniqueAddress removedNode)

    Description copied from interface: RemovedNodePruning

    When the removed node has been removed from the cluster the state changes from that node will be pruned by collapsing the data entries to another node.
