Method Detail

NoDeltaPlaceholder

public ReplicatedDelta NoDeltaPlaceholder()

When a DeltaReplicatedData returns None from delta it must still be treated as a delta that increase the version counter in DeltaPropagationSelector. Otherwise a later delta might be applied before the full state gossip is received and thereby violating RequiresCausalDeliveryOfDeltas.

This is used as a placeholder for such None delta. It's filtered out in createDeltaPropagation, i.e. never sent to the other replicas.

apply

public akka.cluster.ddata.Replicator.Internal.DeltaPropagation apply(UniqueAddress _fromNode,
                                                                     boolean reply,
                                                                     scala.collection.immutable.Map<java.lang.String,akka.cluster.ddata.Replicator.Internal.Delta> deltas)

unapply
