IntermediateResult

public IntermediateResult(IntermediateDataSet intermediateDataSet,
                          ExecutionJobVertex producer,
                          int numParallelProducers,
                          ResultPartitionType resultType)

方法详细资料

setPartition

public void setPartition(int partitionNumber,
                         IntermediateResultPartition partition)

getId

public IntermediateDataSetID getId()

getProducer

public ExecutionJobVertex getProducer()

getPartitions

public IntermediateResultPartition[] getPartitions()

getPartitionById

public IntermediateResultPartition getPartitionById(IntermediateResultPartitionID resultPartitionId)

Returns the partition with the given ID.

参数:

resultPartitionId - ID of the partition to look up

返回:

Intermediate result partition with the given ID
