封闭类:

SideOutputExample

public static final class SideOutputExample.Tokenizer
extends org.apache.flink.streaming.api.functions.ProcessFunction<String,org.apache.flink.api.java.tuple.Tuple2<String,Integer>>

Implements the string tokenizer that splits sentences into words as a user-defined FlatMapFunction. The function takes a line (String) and splits it into multiple pairs in the form of "(word,1)" (Tuple2<String, Integer>).

This rejects words that are longer than 5 characters long.
