方法详细资料

collect

public void collect(StreamRecord<OUT> record)

指定者:

collect 在接口中 org.apache.flink.util.Collector<StreamRecord<OUT>>

collect

public <X> void collect(org.apache.flink.util.OutputTag<X> outputTag,
                        StreamRecord<X> record)

从接口复制的说明: Output

Emits a record to the side output identified by the given OutputTag.

指定者:

collect 在接口中 Output<StreamRecord<OUT>>

record - The record to collect.

emitWatermark

指定者:

emitWatermark 在接口中 Output<StreamRecord<OUT>>

emitWatermarkStatus

public void emitWatermarkStatus(WatermarkStatus watermarkStatus)

指定者:

emitWatermarkStatus 在接口中 Output<StreamRecord<OUT>>

emitLatencyMarker

public void emitLatencyMarker(LatencyMarker latencyMarker)

指定者:

broadcastEvent

public void broadcastEvent(org.apache.flink.runtime.event.AbstractEvent event,
                           boolean isPriorityEvent)
                    throws IOException

抛出:

IOException

alignedBarrierTimeout

public void alignedBarrierTimeout(long checkpointId)
                           throws IOException

抛出:
