Class GSet<T>

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.

Delta

The accumulated delta of mutator operations since previous ResetDelta(). When the Akka.DistributedData.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 Akka.DistributedData.Replicator with the Delta accessor. The modify function shall still return the full state in the same way as IReplicatedData<T> without support for deltas.

MergeDelta(GSet<T>)

When delta is merged into the full state this method is used. When the type GSet<T> of the delta is of the same type as the full state GSet<T> this method can be implemented by delegating to Merge(T).

Declaration
public GSet<T> MergeDelta(GSet<T> delta)
Parameters
Type Name Description
GSet<T> delta
Returns
Type Description
GSet<T>

ResetDelta()

Reset collection of deltas from mutator operations. When the Akka.DistributedData.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 Akka.DistributedData.Replicator with the Delta accessor. When the Akka.DistributedData.Replicator has grabbed the Delta it will invoke this method to get a clean data instance without the delta.

Declaration
public GSet<T> ResetDelta()
Returns
Type Description
GSet<T>
