| 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 |
finish()
This method is called at the end of data processing.
|
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<RowData> element)
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.processElement in interface Input<RowData>Exceptionpublic void finish()
throws Exception
StreamOperatorThe method is expected to flush all remaining buffered data. Exceptions during this flushing of buffered data should be propagated, in order to cause the operation to be recognized as failed, because the last data items are not processed properly.
After this method is called, no more records can be produced for the downstream operators.
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:This method does not need to close any resources. You should release external
resources in the StreamOperator.close() method.
finish in interface StreamOperator<Object>finish in class AbstractStreamOperator<Object>Exception - An exception in this method causes the operator to fail.public void close()
throws Exception
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.
