trait DeltaReplicatedData extends ReplicatedData
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'}.

abstract
type
D <: ReplicatedDelta
The type of the delta.
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 exampleGSet
uses the same type andORSet
uses different types. -

type
T <: ReplicatedData
The type of the concrete implementation, e.g.
The type of the concrete implementation, e.g.
GSet[A]

delta: Option[D]
The accumulated delta of mutator operations since previous #resetDelta.
The accumulated delta of mutator operations since previous #resetDelta. When the
Replicator
invokes themodify
function of theUpdate
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 theReplicator
with the #delta accessor. Themodify
function shall still return the full state in the same way asReplicatedData
without support for deltas. -

Monotonic merge function.
Monotonic merge function.

mergeDelta(thatDelta: D): T
When delta is merged into the full state this method is used.
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 stateT
this method can be implemented by delegating tomerge
. -
abstract
def
resetDelta: T
Reset collection of deltas from mutator operations.
Reset collection of deltas from mutator operations. When the
Replicator
invokes themodify
function of theUpdate
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 theReplicator
with the #delta accessor. When theReplicator
has grabbed thedelta
it will invoke this method to get a clean data instance without the delta.
