emitResult(Tuple3<String,byte[],Integer> resultTuple)
Sends the execution result to the downstream operator.

protected FlinkFnApi.UserDefinedAggregateFunctions |
getUserDefinedFunctionsProto()
Gets the proto representation of the Python user-defined aggregate functions to be executed.
|
void |
onEventTime(InternalTimer<RowData,VoidNamespace> timer)
Invoked when an event-time timer fires.
|
void |
onProcessingTime(InternalTimer<RowData,VoidNamespace> timer)
Invoked when a processing-time timer fires.
|
void |
open()
This method is called immediately before any elements are processed, it should contain the
operator's initialization logic, e.g. state initialization.
