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

Class InternalOneInputWindowStreamProcessFunction<IN,OUT,W extends org.apache.flink.streaming.api.windowing.windows.Window>

java.lang.Object
org.apache.flink.datastream.impl.extension.window.function.InternalOneInputWindowStreamProcessFunction<IN,OUT,W>
Type Parameters:
IN - Type of the 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.OneInputStreamProcessFunction<IN,OUT>, org.apache.flink.datastream.api.function.ProcessFunction
public class InternalOneInputWindowStreamProcessFunction<IN,OUT,W extends org.apache.flink.streaming.api.windowing.windows.Window> extends Object implements org.apache.flink.datastream.api.function.OneInputStreamProcessFunction<IN,OUT>
A class that wrap a OneInputWindowStreamProcessFunction to process function. This will be translated to a window operator instead of vanilla process operator.
