All Implemented Interfaces:
Transition<VMState>, VMTransition
public class ShutdownVM
extends Object
implements VMTransition
Model an action that stop a running VM. An estimation of the action duration must be provided through a ActionDurationEvaluator accessible from ReconfigurationProblem.getDurationEvaluators() with the key ShutdownVM.class
