Method Summary

Modifier and Type	Method and Description
void	endInput() It is notified that no more data will arrive from the input.

Method Detail

processElement

public void processElement(StreamRecord<CommittableMessage<FileSinkCommittable>> 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<CommittableMessage<FileSinkCommittable>>

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

initializeState

public void initializeState(StateInitializationContext context)
                     throws Exception

Description copied from class: AbstractStreamOperator

Stream operators with state which can be restored need to override this hook method.

Specified by:

initializeState in interface StreamOperatorStateHandler.CheckpointedStreamOperator

Overrides:

initializeState in class AbstractStreamOperator<Either<CommittableMessage<FileSinkCommittable>,CompactorRequest>>

Parameters:

context - context that allows to register different states.

Throws:

Exception
