Method Summary

Modifier and Type	Method and Description
void	open() This method is called immediately before any elements are processed, it should contain the operator's initialization logic, e.g. state initialization.
void	processElement(StreamRecord<E> element) Processes one element that arrived on this input of the MultipleInputStreamOperator.
void	processWatermark(Watermark mark) Processes a Watermark that arrived on the first input of this two-input operator.

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<RowData>

Overrides:

open in class TableStreamOperator<RowData>

Throws:

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

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<E>

Overrides:

processWatermark in class TableStreamOperator<RowData>

Throws:

Exception

See Also:

Watermark

processElement

public void processElement(StreamRecord<E> 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<E>

Throws:

Exception
