Class ObservedClusterMembers

java.lang.Object

org.neo4j.kernel.ha.cluster.member.ObservedClusterMembers

public class ObservedClusterMembers
extends Object

Keeps list of members, their roles and availability. List is based on different notifications about cluster and HA events. List is basically a 'best guess' of the cluster state because message ordering is not guaranteed. This class should be used only when imprecise state is acceptable.

For up-to-date cluster state use ClusterMembers.
