All Implemented Interfaces:

public class UpgradeCheckNewAppsGuard
extends Object
implements org.springframework.statemachine.guard.Guard<SkipperStateMachineService.SkipperStates,SkipperStateMachineService.SkipperEvents>

A Guard using extended state variable SkipperStateMachineService.SkipperVariables.UPGRADE_STATUS to determine condition based on initialised upgradeStatus flag. Value of a SkipperStateMachineService.SkipperVariables.UPGRADE_STATUS is set in UpgradeCheckTargetAppsAction and as this same guard is used to protect 'succeed' and 'failure' transitions, upgradeStatus is simply used to differentiate between the two.
