void |
open()
This method is called immediately before any elements are processed, it should contain the
operator's initialization logic, e.g.
|
void |
processElement(StreamRecord<IN> element)
Processes one element that arrived on this input of the
MultipleInputStreamOperator . |
void |
processWatermark(Watermark mark)
Processes a
Watermark that arrived on the first input of this two-input operator. |
