org.apache.flink.streaming.api.operators.co.BatchCoBroadcastWithKeyedOperator<KS,IN1,IN2,OUT>

类型参数:

KS - The key type of the input keyed stream.

IN1 - The input type of the keyed (non-broadcast) side.

IN2 - The input type of the broadcast side.

OUT - The output type of the operator.

所有已实现的接口:

Serializable, org.apache.flink.api.common.state.CheckpointListener, BoundedMultiInput, KeyContext, OutputTypeConfigurable<OUT>, SetupableStreamOperator<OUT>, StreamOperator<OUT>, StreamOperatorStateHandler.CheckpointedStreamOperator, Triggerable<KS,org.apache.flink.runtime.state.VoidNamespace>, TwoInputStreamOperator<IN1,IN2,OUT>

@Internal
public class BatchCoBroadcastWithKeyedOperator<KS,IN1,IN2,OUT>
extends CoBroadcastWithKeyedOperator<KS,IN1,IN2,OUT>
implements BoundedMultiInput

A TwoInputStreamOperator for executing KeyedBroadcastProcessFunctions in RuntimeExecutionMode.BATCH execution mode.

Compared to CoBroadcastWithKeyedOperator this does an additional sanity check on the input processing order requirement.

方法详细资料

endInput

public void endInput(int inputId)
              throws Exception

从接口复制的说明: BoundedMultiInput

It is notified that no more data will arrive from the input identified by the inputId. The inputId is numbered starting from 1, and `1` indicates the first input.

WARNING: It is not safe to use this method to commit any transactions or other side effects! You can use this method to e.g. flush data buffered for the given input or implement an ordered reading from multiple inputs via InputSelectable.

指定者:

endInput 在接口中 BoundedMultiInput

抛出:

Exception

processElement1

public void processElement1(StreamRecord<IN1> element)
                     throws Exception

从接口复制的说明: TwoInputStreamOperator

Processes one element that arrived on the first input of this two-input operator. This method is guaranteed to not be called concurrently with other methods of the operator.

指定者:

processElement1 在接口中 TwoInputStreamOperator<IN1,IN2,OUT>

覆盖:

processElement1 在类中 CoBroadcastWithKeyedOperator<KS,IN1,IN2,OUT>

抛出:

Exception
