 SpaceCopyReplicaParameters parameters,
 Object requestContext)

Method Details

buildDataProducers

protected abstract List<ISingleStageReplicaDataProducer<? extends IExecutableSpaceReplicaData>> buildDataProducers(SpaceCopyReplicaParameters parameters)

produceNextData

public IExecutableSpaceReplicaData produceNextData(ISynchronizationCallback synchCallback)

Description copied from interface: ISingleStageReplicaDataProducer

Produce next data needed for replica, this call will always be followed by #releaseLockedData(ISpaceReplicaData) if lockedData is true, it should keep that item represented by this data locked until the release is called This is done in order to ensure synchronization correctness

Specified by:

produceNextData in interface ISingleStageReplicaDataProducer<IExecutableSpaceReplicaData>

Parameters:

synchCallback - callback to the synchronization processor that needs to be called safely under lock

Returns:

next data needed for replica, null if done. Once null is returns all executive calls must return null!

close

public ISingleStageReplicaDataProducer.CloseStatus close(boolean forced)

Description copied from interface: ISingleStageReplicaDataProducer

Closes the producer, frees up resources held in order to service the replica request.

Specified by:

close in interface ISingleStageReplicaDataProducer<IExecutableSpaceReplicaData>

Returns:

true if any thread is trying to close and the lease reaper thread is trying to close at the same time.

onClose

protected void onClose()

nextReplicaStage

public CurrentStageInfo nextReplicaStage()

Specified by:

nextReplicaStage in interface ISpaceReplicaDataProducer<IExecutableSpaceReplicaData>

getLogPrefix

protected String getLogPrefix()

dumpState

public String dumpState()

Specified by:

dumpState in interface ISingleStageReplicaDataProducer<IExecutableSpaceReplicaData>
