方法详细资料

setChannelStateWriter

public void setChannelStateWriter(ChannelStateWriter channelStateWriter)

从接口复制的说明: ChannelStateHolder

Injects the ChannelStateWriter. Must only be called once.

指定者:

setChannelStateWriter 在接口中 ChannelStateHolder

toInputChannel

public final InputChannel toInputChannel()
                                  throws IOException

抛出:

IOException

checkpointStopped

public void checkpointStopped(long checkpointId)

从类复制的说明: InputChannel

Called by task thread on cancel/complete to clean-up temporary data.

覆盖:

checkpointStopped 在类中 InputChannel

toInputChannelInternal

protected abstract InputChannel toInputChannelInternal()
                                                throws IOException

抛出:

IOException

onRecoveredStateBuffer

public void onRecoveredStateBuffer(Buffer buffer)

finishReadRecoveredState

public void finishReadRecoveredState()
                              throws IOException

抛出:

IOException

resumeConsumption

public void resumeConsumption()

从类复制的说明: InputChannel

After sending a CheckpointBarrier of exactly-once mode, the upstream will be blocked and become unavailable. This method tries to unblock the corresponding upstream and resume data consumption.

指定者:

resumeConsumption 在类中 InputChannel

acknowledgeAllRecordsProcessed

public void acknowledgeAllRecordsProcessed()
                                    throws IOException

从类复制的说明: InputChannel

When received EndOfData from one channel, it need to acknowledge after this event get processed.

指定者:

acknowledgeAllRecordsProcessed 在类中 InputChannel

抛出:

IOException

getNumberOfQueuedBuffers

@VisibleForTesting
protected int getNumberOfQueuedBuffers()

requestBufferBlocking

public Buffer requestBufferBlocking()
                             throws InterruptedException,
                                    IOException

抛出:

InterruptedException

IOException

checkpointStarted

public void checkpointStarted(CheckpointBarrier barrier)
                       throws CheckpointException

从类复制的说明: InputChannel

Called by task thread when checkpointing is started (e.g., any input channel received barrier).

覆盖:

checkpointStarted 在类中 InputChannel

抛出:

CheckpointException
