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

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
