final class ORMultiMap[A, B] extends DeltaReplicatedData with ReplicatedDataSerialization with RemovedNodePruning

An immutable multi-map implementation. This class wraps an ORMap with an ORSet for the map's value.

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

Note that on concurrent adds and removals for the same key (on the same set), removals can be lost.

Type Members

  1. type D = DeltaOp

    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.

  12. def delta: Option[D]

    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.

    Replace an element of a set associated with a key with a new one if it is different.

    Replace an element of a set associated with a key with a new one if it is different. This is useful when an element is removed and another one is added within the same Update. The order of addition and removal is important in order to retain history for replicated data.

  44. def resetDelta: ORMultiMap[A, B]

    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.
