RemovedNodePruning

All Superinterfaces:

ReplicatedData

All Known Implementing Classes:

GCounter, LWWMap, ManyVersionVector, OneVersionVector, ORMap, ORMultiMap, ORSet, PNCounter, PNCounterMap, VersionVector
```
public interface RemovedNodePruning
extends ReplicatedData
```
ReplicatedData that has support for pruning of data belonging to a specific node may implement this interface. When a node is removed from the cluster these methods will be used by the Replicator to collapse data from the removed node into some other node in the cluster.
See process description in the 'CRDT Garbage' section of the Replicator documentation.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`scala.collection.immutable.Set<UniqueAddress>`	`modifiedByNodes()`	The nodes that have changed the state for this data and would need pruning when such node is no longer part of the cluster.
`boolean`	`needPruningFrom(UniqueAddress removedNode)`	Does it have any state changes from a specific node, which has been removed from the cluster.
`RemovedNodePruning`	`prune(UniqueAddress removedNode, UniqueAddress collapseInto)`	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.
`RemovedNodePruning`	`pruningCleanup(UniqueAddress removedNode)`	Remove data entries from a node that has been removed from the cluster and already been pruned.
