Class CronPolicy

java.lang.Object

org.ow2.proactive.resourcemanager.nodesource.policy.NodeSourcePolicy

org.ow2.proactive.resourcemanager.nodesource.policy.CronPolicy

All Implemented Interfaces:

Serializable, org.objectweb.proactive.Active, org.objectweb.proactive.InitActive, NodeSourcePlugin

public class CronPolicy
extends NodeSourcePolicy
implements org.objectweb.proactive.InitActive

Allocated nodes for specified time slot: from "acquire time" to "release time" with specified period. Remove nodes preemptively if "preemptive" parameter is set to true.
If period is zero then acquisition will be performed once.
NOTE: difference between acquire and release time have to be bigger than time required to nodes all acquisition. Period have to be enough to release all nodes.
