ClusterNode

java.lang.Object

public class ClusterNode extends Object implements Comparable, Serializable, Cloneable

Replacement for a JG IpAddress that doesn't base its representation on the JG address but on the computed node name added to the IPAddress instead. This is to avoid any problem in the cluster as some nodes may interpret a node name differently (IP resolution, name case, FQDN or host name, etc.)
