Method Detail

open

public void open()
          throws Exception

Description copied from class: 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.

Specified by:

open in interface StreamOperator<IN1>

Overrides:

open in class AbstractUdfStreamOperator<OUT,TwoInputBroadcastStreamProcessFunction<IN1,IN2,OUT>>

Throws:

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

processElement1

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

Description copied from interface: 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.

Specified by:

processElement1 in interface TwoInputStreamOperator<IN1,IN2,OUT>

Throws:

Exception

processElement2

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

Description copied from interface: 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.

Specified by:

processElement2 in interface TwoInputStreamOperator<IN1,IN2,OUT>

Throws:

Exception

getOutputCollector

protected TimestampCollector<OUT> getOutputCollector()

getNonPartitionedContext

protected NonPartitionedContext<OUT> getNonPartitionedContext()

endInput

public void endInput(int inputId)
              throws Exception

Description copied from interface: 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.

Specified by:

endInput in interface BoundedMultiInput

Throws:

Exception

currentKey

protected Object currentKey()

getProcessingTimeManager

protected ProcessingTimeManager getProcessingTimeManager()
