final case class GSet[A] extends DeltaReplicatedData with ReplicatedDelta with ReplicatedDataSerialization with FastMerge with Product with Serializable

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.

Type Members

  1. type D = GSet[A]

    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 example GSet uses the same type and ORSet uses different types.

  2. type T = GSet[A]

    The type of the concrete implementation, e.g.

    The type of the concrete implementation, e.g. GSet[A]. To be specified by subclass.

  11. val delta: Option[GSet[A]]

    The accumulated delta of mutator operations since previous #resetDelta.

    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.

  29. def resetDelta: GSet[A]

    Reset collection of deltas from mutator operations.

    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.

  36. def zero: GSet[A]

    The empty full state.

    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.
