final class ORMap[A, B <: ReplicatedData] extends DeltaReplicatedData with ReplicatedDataSerialization with RemovedNodePruning

Implements a 'Observed Remove Map' CRDT, also called a 'OR-Map'.

It has similar semantics as an ORSet, but in case of concurrent updates the values are merged, and must therefore be ReplicatedData types themselves.

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

    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.

    Adds an entry to the map.

    Adds an entry to the map. Note that the new value will be merged with existing values on other nodes and the outcome depends on what ReplicatedData type that is used.

    Consider using #updated instead of put if you want modify existing entry.

    IllegalArgumentException is thrown if you try to replace an existing ORSet value, because important history can be lost when replacing the ORSet and undesired effects of merging will occur. Use ORMultiMap or #updated instead.

When the Replicator has grabbed the delta it will invoke this method to get a clean data instance without the delta.
