类 ResultPartitionManager

java.lang.Object

org.apache.flink.runtime.io.network.partition.ResultPartitionManager

所有已实现的接口:

ResultPartitionProvider

public class ResultPartitionManager
extends Object
implements ResultPartitionProvider

The result partition manager keeps track of all currently produced/consumed partitions of a task manager.

ResultSubpartitionView	createSubpartitionView(ResultPartitionID partitionId, ResultSubpartitionIndexSet subpartitionIndexSet, BufferAvailabilityListener availabilityListener) Returns the requested intermediate result partition input view.
Optional<ResultSubpartitionView>	createSubpartitionViewOrRegisterListener(ResultPartitionID partitionId, ResultSubpartitionIndexSet subpartitionIndexSet, BufferAvailabilityListener availabilityListener, PartitionRequestListener partitionRequestListener) If the upstream task's partition has been registered, returns the result subpartition input view immediately, otherwise register the listener and return empty.
