```
public scala.Option<ORSet.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.

    Removes an element from the set.
  - clear
```
public ORSet<A> clear(SelfUniqueAddress node)
```
    Removes all elements from the set, but keeps the history. This has the same result as using {@link ORSet#remove(node:akka\.cluster\.ddata\.SelfUniqueAddress*} for each element, but it is more efficient.

```
public ORSet<A> merge(ORSet<A> that)
```
    When element is in this Set but not in that Set: Compare the "birth dot" of the present element to the version vector in the Set it is absent from. If the element dot is not "seen" by other Set version vector, that means the other set has yet to see this add, and the element is to be in the merged Set. If the other Set version vector dominates the dot, that means the other Set has removed the element already, and the element is not to be in the merged Set.
    When element in both this Set and in that Set: Some dots may still need to be shed. If this Set has dots that the other Set does not have, and the other Set version vector dominates those dots, then we need to drop those dots. Keep only common dots, and dots that are not dominated by the other sides version vector

  - resetDelta
```
public ORSet<A> resetDelta()
```
    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.
