Class DiffableStringMap

java.lang.Object
java.util.AbstractMap<java.lang.String,​java.lang.String>
org.elasticsearch.cluster.metadata.DiffableStringMap
All Implemented Interfaces:
java.util.Map<java.lang.String,​java.lang.String>, Diffable<DiffableStringMap>, Writeable
public class DiffableStringMap
extends java.util.AbstractMap<java.lang.String,​java.lang.String>
implements Diffable<DiffableStringMap>
This is a Map<String, String> that implements AbstractDiffable so it can be used for cluster state purposes
