类 InputGateWithMetrics

java.lang.Object

org.apache.flink.runtime.io.network.partition.consumer.InputGate

org.apache.flink.runtime.taskmanager.InputGateWithMetrics

所有已实现的接口:

AutoCloseable, AvailabilityProvider, PullingAsyncDataInput<BufferOrEvent>

public class InputGateWithMetrics
extends InputGate

This class wraps InputGate provided by shuffle service and it is mainly used for increasing general input metrics from TaskIOMetricGroup.

InputGateWithMetrics

public InputGateWithMetrics(InputGate inputGate,
                            org.apache.flink.metrics.Counter numBytesIn)

方法详细资料

getAvailableFuture

public CompletableFuture<?> getAvailableFuture()

指定者:

getAvailableFuture 在接口中 AvailabilityProvider

覆盖:

getAvailableFuture 在类中 InputGate

返回:

a future that is completed if there are more records available. If there are more records available immediately, AvailabilityProvider.AVAILABLE should be returned. Previously returned not completed futures should become completed once there are more records available.

getNumberOfInputChannels

public int getNumberOfInputChannels()

指定者:

getNumberOfInputChannels 在类中 InputGate

isFinished

public boolean isFinished()

指定者:

isFinished 在接口中 PullingAsyncDataInput<BufferOrEvent>

指定者:

isFinished 在类中 InputGate

返回:

true if is finished and for example end of input was reached, false otherwise.

setup

public void setup()
           throws IOException,
                  InterruptedException

从类复制的说明: InputGate

Setup gate, potentially heavy-weight, blocking operation comparing to just creation.

指定者:

setup 在类中 InputGate

抛出:

IOException

InterruptedException

getNext

public Optional<BufferOrEvent> getNext()
                                throws IOException,
                                       InterruptedException

从类复制的说明: InputGate

Blocking call waiting for next BufferOrEvent.

Note: It should be guaranteed that the previous returned buffer has been recycled before getting next one.

指定者:

getNext 在类中 InputGate

返回:

Optional.empty() if InputGate.isFinished() returns true.

抛出:

IOException

InterruptedException

pollNext

public Optional<BufferOrEvent> pollNext()
                                 throws IOException,
                                        InterruptedException

从类复制的说明: InputGate

Poll the BufferOrEvent.

Note: It should be guaranteed that the previous returned buffer has been recycled before polling next one.

指定者:

pollNext 在接口中 PullingAsyncDataInput<BufferOrEvent>

指定者:

pollNext 在类中 InputGate

返回:

Optional.empty() if there is no data to return or if InputGate.isFinished() returns true.

抛出:

IOException

InterruptedException

sendTaskEvent

public void sendTaskEvent(TaskEvent event)
                   throws IOException

指定者:

sendTaskEvent 在类中 InputGate

抛出:

IOException

close

public void close()
           throws Exception

抛出:

Exception
