Package org.apache.flink.datastream.impl.extension.window.function

Class InternalTwoInputWindowStreamProcessFunction<IN1,IN2,OUT,W extends org.apache.flink.streaming.api.windowing.windows.Window>

java.lang.Object

org.apache.flink.datastream.impl.extension.window.function.InternalTwoInputWindowStreamProcessFunction<IN1,IN2,OUT,W>

Type Parameters:

IN1 - Type of the first input elements.

IN2 - Type of the second input elements.

OUT - Type of the output elements.

W - Type of the window.

All Implemented Interfaces:

Serializable, org.apache.flink.api.common.functions.Function, org.apache.flink.datastream.api.function.ProcessFunction, org.apache.flink.datastream.api.function.TwoInputNonBroadcastStreamProcessFunction<IN1,IN2,OUT>

public class InternalTwoInputWindowStreamProcessFunction<IN1,IN2,OUT,W extends org.apache.flink.streaming.api.windowing.windows.Window>
extends Object
implements org.apache.flink.datastream.api.function.TwoInputNonBroadcastStreamProcessFunction<IN1,IN2,OUT>

A class that wrap a TwoInputNonBroadcastWindowStreamProcessFunction to process function. This will be translated to a window operator instead of vanilla process operator.
