- Constructor Detail
  - AtomicDeltaOp
```
public AtomicDeltaOp()
```
    Implements a 'Observed Remove Map' CRDT, also called a 'OR-Map'.
    It has similar semantics as an ORSet, but in case of concurrent updates the values are merged, and must therefore be ReplicatedData types themselves.
    This class is immutable, i.e. "modifying" methods return a new instance.

  - deltaSize
```
public int deltaSize()
```
    Specified by:
    
    deltaSize in interface ReplicatedDeltaSize
  - merge
```
public ORMap.DeltaOp merge(ORMap.DeltaOp that)
```
  - underlying
```
public abstract ORSet.DeltaOp underlying()
```
  - zero
```
public DeltaReplicatedData zero()
```
    Description copied from interface: ReplicatedDelta
    
    The empty full state. This is used when a delta is received and no existing full state exists on the receiving side. Then the delta is merged into the zero to create the initial full state.
