Deprecated.
This method is called immediately before any elements are processed, it should contain the
operator's initialization logic, e.g. state initialization.
|
void |
processElement1(StreamRecord<IN1> element)
Deprecated.
Processes one element that arrived on the first input of this two-input operator.
|
void |
processElement2(StreamRecord<IN2> element)
Deprecated.
Processes one element that arrived on the second input of this two-input operator.
