It is notified that no more data will arrive from the input identified by the
inputId . |

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

inputId
. The inputId
is numbered starting from 1, and `1` indicates the first input.
WARNING: It is not safe to use this method to commit any transactions or other side
effects! You can use this method to e.g. flush data buffered for the given input or implement
an ordered reading from multiple inputs via InputSelectable
.
