Package org.elasticsearch.cluster.metadata

Class DiffableStringMap

java.lang.Object

java.util.AbstractMap<String,String>

org.elasticsearch.cluster.metadata.DiffableStringMap

All Implemented Interfaces:

Map<String,String>, Diffable<DiffableStringMap>, Writeable

public class DiffableStringMap
extends AbstractMap<String,String>
implements Diffable<DiffableStringMap>

This is a Map<String, String> that implements AbstractDiffable so it can be used for cluster state purposes
