Class GCounter

    • Method Detail

      • empty

        public static GCounter empty()
      • apply

        public static GCounter apply()
      • create

        public static GCounter create()
        Java API
      • unapply

        public static scala.Option<scala.math.BigInt> unapply​(GCounter c)
        Extract the value().
      • delta

        public scala.Option<GCounter> 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.
        Specified by:
        delta in interface DeltaReplicatedData
      • value

        public scala.math.BigInt value()
        Scala API: Current total value of the counter.
      • getValue

        public java.math.BigInteger getValue()
        Java API: Current total value of the counter.
      • $colon$plus

        public GCounter $colon$plus​(long n,
                                    SelfUniqueAddress node)
        Increment the counter with the delta n specified. The delta must be zero or positive.
      • increment

        public GCounter increment​(SelfUniqueAddress node,
                                  long n)
        Increment the counter with the delta n specified. The delta n must be zero or positive.
      • zero

        public GCounter 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.
        Specified by:
        zero in interface ReplicatedDelta
      • resetDelta

        public GCounter 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.

      • modifiedByNodes

        public scala.collection.immutable.Set<UniqueAddress> modifiedByNodes()
        Description copied from interface: RemovedNodePruning
        The nodes that have changed the state for this data and would need pruning when such node is no longer part of the cluster.
        Specified by:
        modifiedByNodes in interface RemovedNodePruning
