      • biStreaming

        public static reactor.core.publisher.Flux<org.springframework.messaging.Message<byte[]>> biStreaming​(reactor.core.publisher.Flux<org.springframework.messaging.Message<byte[]>> inputStream)
        Utility method to support bi-directional streaming interaction. Will connect to gRPC server using default host/port, otherwise use biStreaming(String, int, Flux) method. Keep in mind that there is no implied relationship between input stream and output stream. They are completely independent where one may end before the other.
        Parameters:
        inputStream - FluxMessage<byte[]>> representing input stream.
        Returns:
        Flux<Message<byte[]>> representing output stream

        Utility method to support bi-directional streaming interaction. Keep in mind that there is no implied relationship between input stream and output stream. They are completely independent where one may end before the other.
        Parameters:
        host - gRPC server host name
        port - gRPC server port
        inputStream - FluxMessage<byte[]>> representing input stream
        Returns:
