类 WordCount.Tokenizer

java.lang.Object

org.apache.flink.streaming.examples.wordcount.WordCount.Tokenizer

所有已实现的接口:

Serializable, org.apache.flink.api.common.functions.FlatMapFunction<String,org.apache.flink.api.java.tuple.Tuple2<String,Integer>>, org.apache.flink.api.common.functions.Function

封闭类:

WordCount

public static final class WordCount.Tokenizer
extends Object
implements org.apache.flink.api.common.functions.FlatMapFunction<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>).
