Methods

Modifier and Type	Method and Description
void	addProcessedRecords(int records)
void	cancelPartitionState()
JobPartitionState[]	getPartitionStates() Returns an array of JobPartitionStates holding information about the processing state (JobPartitionState.State) and the processing owner of this partition. The index of the JobPartitionState inside of the array is the number of the processed partition if the KeyValueSource is PartitionIdAware or a randomly assigned id for the different members of the cluster.
int	getProcessedRecords() Returns the number of processed records. The number of processed records is not a real time value, it is updated on a regular basis (after 1000 processed elements per node).

Method Detail

getPartitionStates

public JobPartitionState[] getPartitionStates()

Description copied from interface: JobProcessInformation

Returns an array of JobPartitionStates holding information about the processing state (JobPartitionState.State) and the processing owner of this partition.
The index of the JobPartitionState inside of the array is the number of the processed partition if the KeyValueSource is PartitionIdAware or a randomly assigned id for the different members of the cluster.

Specified by:

getPartitionStates in interface JobProcessInformation

Returns:

partition state array with actual state information

getProcessedRecords

public int getProcessedRecords()

Description copied from interface: JobProcessInformation

Returns the number of processed records.
The number of processed records is not a real time value, it is updated on a regular basis (after 1000 processed elements per node).

Specified by:

getProcessedRecords in interface JobProcessInformation

Returns:

number of processed records

addProcessedRecords

public void addProcessedRecords(int records)

cancelPartitionState

public void cancelPartitionState()

updatePartitionState

public boolean updatePartitionState(int partitionId,
                           JobPartitionState oldPartitionState,
                           JobPartitionState newPartitionState)

updatePartitionState

public boolean updatePartitionState(JobPartitionState[] oldPartitionStates,
                           JobPartitionState[] newPartitionStates)
