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

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

  • 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.
