ClassDescriptionThe base class containing the functionality available to all broadcast process function.BroadcastProcessFunction<IN1,
IN2, OUT> A function to be applied to aBroadcastConnectedStreamthat connectsBroadcastStream, i.e.CoFlatMapFunction<IN1,IN2, OUT> A CoFlatMapFunction implements a flat-map transformation over two connected streams.CoMapFunction<IN1,IN2, OUT> A CoFlatMapFunction implements a map() transformation over two connected streams.CoProcessFunction<IN1,IN2, OUT> A function that processes elements of two streams and produces a single output one.KeyedBroadcastProcessFunction<KS,IN1, IN2, OUT> A function to be applied to aBroadcastConnectedStreamthat connectsBroadcastStream, i.e.KeyedCoProcessFunction<K,IN1, IN2, OUT> A function that processes elements of two keyed streams and produces a single output one.ProcessJoinFunction<IN1,IN2, OUT> A function that processes two joined elements and produces a single output one.
