Method Detail

processElement

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

Description copied from interface: Input

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

Specified by:

processElement in interface Input<RowData>

Throws:

Exception

processWatermark

public void processWatermark(Watermark mark)
                      throws Exception

Description copied from interface: Input

Processes a Watermark 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:

processWatermark in interface Input<RowData>

Throws:

Exception

Watermark

processLatencyMarker

public void processLatencyMarker(LatencyMarker latencyMarker)
                          throws Exception

Description copied from interface: Input

Processes a LatencyMarker 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:

processLatencyMarker in interface Input<RowData>

Throws:

Exception

See Also:

processWatermarkStatus

public void processWatermarkStatus(WatermarkStatus watermarkStatus)
                            throws Exception

Description copied from interface: Input

Processes a WatermarkStatus that arrived on this input of the MultipleInputStreamOperator. This method is guaranteed to not be called concurrently with other methods of the operator.

Specified by:

processWatermarkStatus in interface Input<RowData>

Throws:

Exception

WatermarkStatus

isAsyncStateProcessingEnabled

@Internal
public final boolean isAsyncStateProcessingEnabled()

Description copied from interface: AsyncStateProcessing

Get if the async state processing is enabled for this input/operator.

Specified by:

isAsyncStateProcessingEnabled in interface AsyncStateProcessing

Returns:

ture if async state processing is enabled.

getRecordProcessor

@Internal
public final <T> ThrowingConsumer<StreamRecord<T>,Exception> getRecordProcessor(int inputId)

Description copied from interface: AsyncStateProcessing

Get the record processor that could process record from input, which is the only entry for async processing.

Specified by:

getRecordProcessor in interface AsyncStateProcessing

Parameters:

inputId - the input identifier, start from 1. Borrow the design from org.apache.flink.streaming.api.operators.AbstractInput#inputId. This is only relevant if there is multiple inputs for the instance.
