void |
emitResult(Tuple2<byte[],Integer> resultTuple)
Sends the execution result to the downstream operator.
|
void |
onEventTime(InternalTimer<K,VoidNamespace> timer)
Invoked when an event-time timer fires.
|
void |
onProcessingTime(InternalTimer<K,VoidNamespace> timer)
Invoked when a processing-time timer fires.
