Method Summary

Modifier and Type	Method and Description
void	endInput() It is notified that no more data will arrive from the input.
void	open() This method is called immediately before any elements are processed, it should contain the operator's initialization logic, e.g.
void	processElement(StreamRecord<RowData> element) Processes one element that arrived on this input of the MultipleInputStreamOperator.

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.

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

endInput

public void endInput()
              throws Exception

Description copied from interface: BoundedOneInput

It is notified that no more data will arrive from the input.

WARNING: It is not safe to use this method to commit any transactions or other side effects! You can use this method to flush any buffered data that can later on be committed e.g. in a CheckpointListener.notifyCheckpointComplete(long).

NOTE: Given it is semantically very similar to the StreamOperator.finish() method. It might be dropped in favour of the other method at some point in time.

Specified by:

endInput in interface BoundedOneInput

Throws:

Exception
