DeltaReplicatedData
ReplicatedData with additional support for delta-CRDT replication. delta-CRDT is a way to reduce the need for sending the full state for updates. For example adding element 'c' and 'd' to set {'a', 'b'} would result in sending the delta {'c', 'd'} and merge that with the state on the receiving side, resulting in set {'a', 'b', 'c', 'd'}.

Types
The type of the delta. To be specified by subclass.
It may be the same type as T
or a different type if needed.
For example GSet
uses the same type and ORSet
uses different types.

Abstract methods
The accumulated delta of mutator operations since previous
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 delta accessor. The
modify
function shall still return the full state in the same way as
ReplicatedData
without support for deltas.

When delta is merged into the full state this method is used.
When the type D
of the delta is of the same type as the full state T
this method can be implemented by delegating to merge
.

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 delta accessor. When the Replicator
has
grabbed the delta
it will invoke this method to get a clean data instance
without the delta.
