Class WordCount.Tokenizer

java.lang.Object
org.apache.flink.streaming.examples.dsv2.wordcount.WordCount.Tokenizer
All Implemented Interfaces:
Serializable, org.apache.flink.api.common.functions.Function, org.apache.flink.datastream.api.function.OneInputStreamProcessFunction<String,org.apache.flink.api.java.tuple.Tuple2<String,Integer>>, org.apache.flink.datastream.api.function.ProcessFunction
Enclosing class:
WordCount
public static final class WordCount.Tokenizer extends Object implements org.apache.flink.datastream.api.function.OneInputStreamProcessFunction<String,org.apache.flink.api.java.tuple.Tuple2<String,Integer>>
Implements the string tokenizer that splits sentences into words as a user-defined ProcessFunction. The process function takes a line (String) and splits it into multiple pairs in the form of "(word,1)" (Tuple2<String, Integer>).
