    public class TwoOutputProcessOperator<IN,​OUT_MAIN,​OUT_SIDE>
extends org.apache.flink.streaming.api.operators.AbstractUdfStreamOperator<OUT_MAIN,​org.apache.flink.datastream.api.function.TwoOutputStreamProcessFunction<IN,​OUT_MAIN,​OUT_SIDE>>
implements org.apache.flink.streaming.api.operators.OneInputStreamOperator<IN,​OUT_MAIN>, org.apache.flink.streaming.api.operators.BoundedOneInput
    Operator for TwoOutputStreamProcessFunction.

    We support the second output via flink side-output mechanism.
