Class RMNodeEvent

java.lang.Object

org.ow2.proactive.resourcemanager.common.event.RMEvent

org.ow2.proactive.resourcemanager.common.event.RMNodeEvent

All Implemented Interfaces:

Serializable, Cloneable, Comparable<RMEvent>

@PublicAPI
public final class RMNodeEvent
extends RMEvent

This class implements Event object related to an RMNode This immutable event object is thrown to all Resource Manager Monitors to inform them about a Node's state modification.

This event can be:

• a new Node acquisition.
• a node becoming free.
• a node becoming busy.
• a node becoming to release.
• a node becoming to down.
• a node removed from the Resource Manager.

An RMNodeSourceEvent contains all information about its related RMNode.

Since:

ProActive Scheduling 0.9
