void |
onEventTime(InternalTimer<K,org.apache.flink.runtime.state.VoidNamespace> timer)
Invoked when an event-time timer fires.

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<IN> element)
Processes one element that arrived at this operator.
