Class InstanceId

java.lang.Object

org.neo4j.cluster.InstanceId

All Implemented Interfaces:

Externalizable, Serializable, Comparable<InstanceId>

public class InstanceId
extends Object
implements Externalizable, Comparable<InstanceId>

Represents the concept of the cluster wide unique id of an instance. The main requirement is total order over the instances of the class, currently implemented by an encapsulated integer. It is also expected to be serializable, as it's transmitted over the wire as part of messages between instances.
