abstract class AbstractDeltaReplicatedData[A <: AbstractDeltaReplicatedData[A, B], B <: ReplicatedDelta] extends AbstractReplicatedData[A] with DeltaReplicatedData
Java API: Interface for implementing a DeltaReplicatedData in Java.
The type parameter A
is a self-recursive type to be defined by the
concrete implementation.
E.g. class TwoPhaseSet extends AbstractDeltaReplicatedData<TwoPhaseSet, TwoPhaseSet>

Type Members
- type D = ReplicatedDelta
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 exampleGSet
uses the same type andORSet
uses different types.- Definition Classes
- AbstractDeltaReplicatedData → DeltaReplicatedData
- type T = ReplicatedData
The type of the concrete implementation, e.g.
The type of the concrete implementation, e.g.
GSet[A]
. To be specified by subclass.- Definition Classes

Abstract Value Members
- abstract def deltaData: Optional[B]
The accumulated delta of mutator operations since previous #resetDelta.
The accumulated delta of mutator operations since previous #resetDelta. When the
Replicator
invokes themodify
function of theUpdate
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 theReplicator
with the #deltaData accessor. Themodify
function shall still return the full state in the same way asReplicatedData
without support for deltas. - abstract def mergeData(that: A): A
Java API: Monotonic merge function.
Java API: Monotonic merge function.

- AbstractReplicatedData
- abstract def mergeDeltaData(that: B): A
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 stateT
this method can be implemented by delegating tomergeData
. - abstract def resetDelta: T
Reset collection of deltas from mutator operations.
Reset collection of deltas from mutator operations. When the
Replicator
invokes themodify
function of theUpdate
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 theReplicator
with the #delta accessor. When theReplicator
has grabbed thedelta
it will invoke this method to get a clean data instance without the delta.- Definition Classes
