| Modifier and Type | Method and Description |
|---|---|
void |
bufferInput(RowData input)
Buffers the specified input, it will be used to construct the operator result together with
the user-defined function execution result.
|
void |
emitResult(Tuple3<String,byte[],Integer> resultTuple)
Sends the execution result to the downstream operator.
|
void |
endInput()
It is notified that no more data will arrive from the input.
|
void |
finish()
This method is called at the end of data processing.
|
protected void |
invokeCurrentBatch() |
void |
open()
This method is called immediately before any elements are processed, it should contain the
operator's initialization logic, e.g.

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.

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.
