方法详细资料

emitWatermark

public void emitWatermark(Watermark mark)

从接口复制的说明: Output

Emits a Watermark from an operator. This watermark is broadcast to all downstream operators.

A watermark specifies that no element with a timestamp lower or equal to the watermark timestamp will be emitted in the future.

指定者:

emitWatermark 在接口中 Output<StreamRecord<OUT>>

emitLatencyMarker

public void emitLatencyMarker(LatencyMarker latencyMarker)

指定者:

emitLatencyMarker 在接口中 Output<StreamRecord<OUT>>

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 the side output identified by the given OutputTag.

指定者:

collect 在接口中 Output<StreamRecord<OUT>>

record - The record to collect.

close

public void close()

指定者:

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