Method Detail

newPersistenceInstance

protected abstract T newPersistenceInstance()

Get a new persistence instance

Returns:

the persistence instance

getProcessingPersistence

protected T getProcessingPersistence()

Returns the processing persistence instance

Returns:

the processing persistence instance

suspendProcessing

public IProcessingUnitPersistence suspendProcessing()
                                             throws ProcessingException

Description copied from interface: IProcessingUnit

Suspends the processing: The processing is able to persist its state with the help of the IProcessingUnitPersistence object. On a resume this instance of the IProcessingUnitPersistence will be returned (see method below).

Specified by:

suspendProcessing in interface IProcessingUnit

Overrides:

suspendProcessing in class AbstractProcessingUnitImpl

Returns:

the processing persistence which contains all information to resume processing later (see resumeProcessing).

Throws:

ProcessingException - Throws this exception in case of while suspend the processing any failures occurs.

See Also:

AbstractProcessingUnitImpl.suspendProcessing()

resumeProcessing

public void resumeProcessing(IProcessingUnitPersistence processingPersistence,
                             IProcessingUnitContext processingUnitContext)
                      throws ProcessingException

Description copied from interface: IProcessingUnit

After suspending a processing unit can be resumed. The parameter list of the initialization is passed as well the IProcessingUnitPersistence which was returned by the suspendProcessing method.

Specified by:

resumeProcessing in interface IProcessingUnit

Overrides:

resumeProcessing in class AbstractProcessingUnitImpl

Parameters:

processingPersistence - the processing persistence to resume after suspending.

processingUnitContext - the processing unit context

Throws:

ProcessingException - Throws this exception in case of while resume the processing any failures occurs.
