类 RichCombineToGroupCombineWrapper<IN,OUT,F extends org.apache.flink.api.common.functions.RichGroupReduceFunction<IN,OUT> & org.apache.flink.api.common.functions.CombineFunction<IN,IN>>

java.lang.Object

org.apache.flink.api.common.functions.AbstractRichFunction

org.apache.flink.api.common.functions.RichGroupCombineFunction<IN,IN>

org.apache.flink.api.java.operators.translation.RichCombineToGroupCombineWrapper<IN,OUT,F>

所有已实现的接口:

Serializable, org.apache.flink.api.common.functions.Function, org.apache.flink.api.common.functions.GroupCombineFunction<IN,IN>, org.apache.flink.api.common.functions.GroupReduceFunction<IN,OUT>, org.apache.flink.api.common.functions.RichFunction

public class RichCombineToGroupCombineWrapper<IN,OUT,F extends org.apache.flink.api.common.functions.RichGroupReduceFunction<IN,OUT> & org.apache.flink.api.common.functions.CombineFunction<IN,IN>>
extends org.apache.flink.api.common.functions.RichGroupCombineFunction<IN,IN>
implements org.apache.flink.api.common.functions.GroupReduceFunction<IN,OUT>

A wrapper the wraps a function that implements both CombineFunction and GroupReduceFunction interfaces and makes it look like a function that implements GroupCombineFunction and GroupReduceFunction to the runtime.
