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.

Method Summary

Modifier and Type	Method and Description
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.
