Method Detail

getProcessingUnit

public ProcessingUnit getProcessingUnit()

Returns:

The processing unit this event refers to.

getProcessingUnitInstanceName

public String getProcessingUnitInstanceName()

Returns:

The processing unit instance name this event refers to.

getPreviousStatus

public ProvisionStatus getPreviousStatus()

Returns:

The previous provision status or null if not status was recorded.

getNewStatus

public ProvisionStatus getNewStatus()

Returns:

The current (new) provision status for the specified processing unit instance.

getGridServiceContainer

public GridServiceContainer getGridServiceContainer()

For ProvisionStatus.ATTEMPT - returns the GridServiceContainer a processing unit instance is instantiating on. May be null if not yet discovered. For ProvisionStatus.SUCCESS - returns the GridServiceContainer a processing unit instance has successfully instantiated on. May be null if not yet discovered. For ProvisionStatus.FAILURE - returns the GridServiceContainer a processing unit instance has failed to instantiate on. May be null if no longer available. For ProvisionStatus.PENDING - returns null.

Returns:

The Grid Service Container this provision change refers to. May be null.

getProcessingUnitInstance

public ProcessingUnitInstance getProcessingUnitInstance()

For ProvisionStatus.ATTEMPT - returns null until the processing unit instance is discovered and added. For ProvisionStatus.SUCCESS - returns the ProcessingUnitInstance that has successfully instantiated. May be null if not yet discovered. For ProvisionStatus.FAILURE - returns null. For ProvisionStatus.PENDING - returns null.

Returns:

The Processing Unit Instance (extracted by name) this provision change refers to. May be null.

getProvisionFailure
