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]
.

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.

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
.
The nodes that have changed the state for this data and would need pruning when such node is no longer part of the cluster.
The nodes that have changed the state for this data and would need pruning when such node is no longer part of the cluster.
Does it have any state changes from a specific node, which has been removed from the cluster.
Does it have any state changes from a specific node, which has been removed from the cluster.
When the removed
node has been removed from the cluster the state
changes from that node will be pruned by collapsing the data entries
to another node.
When the removed
node has been removed from the cluster the state
changes from that node will be pruned by collapsing the data entries
to another node.
Remove data entries from a node that has been removed from the cluster and already been pruned.
Remove data entries from a node that has been removed from the cluster and already been pruned.
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 ORMap#updated(node:akka\.cluster\.ddata\.SelfUniqueAddress*
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
ORMap#updated(node:akka\.cluster\.ddata\.SelfUniqueAddress* instead.

Java API Removes an entry from the map. Note that if there is a conflicting update on another node the entry will not be removed after 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.

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.
