public UndeployScaleStrategyBean()
Method Detail

setMachinesSlaEnforcementEndpoint

public void setMachinesSlaEnforcementEndpoint(MachinesSlaEnforcementEndpoint endpoint)
Specified by:
setMachinesSlaEnforcementEndpoint in interface MachinesSlaEnforcementEndpointAware

setContainersSlaEnforcementEndpoint

public void setContainersSlaEnforcementEndpoint(ContainersSlaEnforcementEndpoint containersService)
Specified by:
setContainersSlaEnforcementEndpoint in interface ContainersSlaEnforcementEndpointAware

setGridServiceContainerConfig

public void setGridServiceContainerConfig(org.openspaces.admin.internal.pu.elastic.GridServiceContainerConfig containersConfig)
Specified by:
setGridServiceContainerConfig in interface GridServiceContainerConfigAware

afterPropertiesSet

public void afterPropertiesSet()
Description copied from interface: Bean
Invoked by a bean factory after it has set all bean properties. This method allows the bean instance to perform non-blocking initialization, which is only possible when all bean properties have been set and to throw an exception in the event of misconfiguration.

Specified by:
afterPropertiesSet in interface Bean
Overrides:
afterPropertiesSet in class AbstractScaleStrategyBean

BeanConfigurationException, BeanInitializationException

enforceSla

public void enforceSla()
                throws SlaEnforcementInProgressException
Specified by:
enforceSla in class AbstractScaleStrategyBean
Throws:
SlaEnforcementInProgressException

getConfig

public ScaleStrategyConfig getConfig()
Specified by:
getConfig in interface ScaleStrategyBean

isUndeploying

protected boolean isUndeploying()
Specified by:
isUndeploying in class AbstractScaleStrategyBean
Returns:
true if this is an undeployment strategy (pu is undeploying)

recoverStateOnEsmStart

protected void recoverStateOnEsmStart()
                               throws MachinesSlaEnforcementInProgressException,
                                      SomeProcessingUnitsHaveNotCompletedStateRecoveryException,
                                      NeedToWaitUntilAllGridServiceAgentsDiscoveredException,
                                      UndeployInProgressException
