| Modifier and Type | Method and Description |
|---|---|
void |
close()
This method is called at the very end of the operator's life, both in the case of a
successful completion of the operation, and in the case of a failure and canceling.
|
void |
endInput()
It is notified that no more data will arrive from the input.
|
void |
initializeState(StateInitializationContext context)
Stream operators with state which can be restored need to override this hook method.
|
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<Either<CommittableMessage<FileSinkCommittable>,CompactorRequest>> element)
Processes one element that arrived on this input of the
MultipleInputStreamOperator. |
void |
snapshotState(StateSnapshotContext context)
Stream operators with state, which want to participate in a snapshot need to override this
hook method.

BoundedOneInputWARNING: 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.

StreamOperatorThis method is expected to make a thorough effort to release all resources that the operator has acquired.
NOTE:It can not emit any records! If you need to emit records at the end of
processing, do so in the StreamOperator.finish() method.
