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

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.
Java API
Monotonic merge function.
Monotonic merge function.
When delta is merged into the full state this method is used.
When delta is merged into the full state this method is used.
When the type D
of the delta is of the same type as the full state T
this method can be implemented by delegating to merge
.
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.
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.
(gSet: any2stringadd[GSet[A]]).+(other)
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.
