示例1: execute

@Override
public void execute(TupleWindow inputWindow) {

* The inputWindow gives a view of
* (a) all the events in the window
* (b) events that expired since last activation of the window
* (c) events that newly arrived since last activation of the window
*/

}
/*
* Instead of iterating over all the tuples in the window to compute
* the sum, the values for the new events are added and old events are
* subtracted. Similar optimizations might be possible in other
* windowing computations.
