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

java.lang.Object

org.apache.flink.api.java.operators.translation.CombineToGroupCombineWrapper<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>

@Internal
public class CombineToGroupCombineWrapper<IN,OUT,F extends org.apache.flink.api.common.functions.CombineFunction<IN,IN> & org.apache.flink.api.common.functions.GroupReduceFunction<IN,OUT>>
extends Object
implements org.apache.flink.api.common.functions.GroupCombineFunction<IN,IN>, 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.
