方法详细资料

open

public void open()
          throws Exception

从类复制的说明: AbstractStreamOperator

This method is called immediately before any elements are processed, it should contain the operator's initialization logic, e.g. state initialization.

The default implementation does nothing.

指定者:

open 在接口中 StreamOperator<Object>

覆盖:

open 在类中 AbstractUdfStreamOperator<Object,SinkFunction<IN>>

抛出:

Exception - An exception in this method causes the operator to fail.

processElement

public void processElement(StreamRecord<IN> element)
                    throws Exception

从接口复制的说明: OneInputStreamOperator

Processes one element that arrived at this operator. This method is guaranteed to not be called concurrently with other methods of the operator.

指定者:

processElement 在接口中 OneInputStreamOperator<IN,Object>

抛出:

Exception

reportOrForwardLatencyMarker

protected void reportOrForwardLatencyMarker(LatencyMarker marker)

覆盖:

reportOrForwardLatencyMarker 在类中 AbstractStreamOperator<Object>

processWatermark

public void processWatermark(Watermark mark)
                      throws Exception

从接口复制的说明: OneInputStreamOperator

Processes a Watermark. This method is guaranteed to not be called concurrently with other methods of the operator.

指定者:

processWatermark 在接口中 OneInputStreamOperator<IN,Object>

覆盖:

processWatermark 在类中 AbstractStreamOperator<Object>

抛出:

Exception
