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<OUT>

覆盖:

open 在类中 AbstractUdfStreamOperator<OUT,CoProcessFunction<IN1,IN2,OUT>>

抛出:

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

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>

抛出:

Exception

processElement2

public void processElement2(StreamRecord<IN2> element)
                     throws Exception

从接口复制的说明: TwoInputStreamOperator

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

指定者:

processElement2 在接口中 TwoInputStreamOperator<IN1,IN2,OUT>

抛出:

Exception

processWatermark

public void processWatermark(Watermark mark)
                      throws Exception

覆盖:

processWatermark 在类中 AbstractStreamOperator<OUT>

抛出:

Exception
