I read the doc about ProcessWindowFunction

But I the code on the flink demo is incorrect

public class MyProcessWindowFunction extends ProcessWindowFunction<Tuple<String, Long>, String, String, TimeWindow> {

Tuple cannot have to parameter.

I try to find a demo which ProcessWindowFunction used in window word count demo,

I can not even find a complete correct demo with ProcessWindowFunction.

Can any one show me how to use ProcessWindowFunction in wordcount window function with .process(ProcessWindowFunction) ?
