        public static <A> GSet<A> create()
        Java API
        Returns:
        (undocumented)
      • apply

        public static <A> GSet<A> apply​(scala.collection.immutable.Set<A> elements,
                                        scala.Option<GSet<A>> delta)
        Implements a 'Add Set' CRDT, also called a 'G-Set'. You can't remove elements of a G-Set.

        It is described in the paper A comprehensive study of Convergent and Commutative Replicated Data Types.

        A G-Set doesn't accumulate any garbage apart from the elements themselves.

        This class is immutable, i.e. "modifying" methods return a new instance.

        Parameters:
        elements - (undocumented)
        delta - (undocumented)
        Returns:
        (undocumented)
      • unapply

        public static <A> scala.Option<scala.collection.immutable.Set<A>> unapply​(GSet<A> x$0)
      • elements

        public scala.collection.immutable.Set<A> elements()
      • delta

        public scala.Option<GSet<A>> 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
        Returns:
        (undocumented)
      • getElements

        public java.util.Set<A> getElements()

        Returns:
        (undocumented)
      • contains

        public boolean contains​(A a)
      • isEmpty

        public boolean isEmpty()
      • size

        public int size()
      • $plus

        public GSet<A> $plus​(A element)
        Adds an element to the set
        Parameters:
        element - (undocumented)
        Returns:
        (undocumented)
      • add

        public GSet<A> add​(A element)
        Adds an element to the set
        Parameters:
        element - (undocumented)
        Returns:
        (undocumented)
      • mergeDelta

        public GSet<A> mergeDelta​(GSet<A> thatDelta)
      • resetDelta

        public GSet<A> 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.
        Specified by:
        resetDelta in interface DeltaReplicatedData
        Returns:
        (undocumented)
