    • 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

      public static reactor.core.publisher.Flux<org.springframework.messaging.Message<byte[]>> biStreaming(String host, int port, reactor.core.publisher.Flux<org.springframework.messaging.Message<byte[]>> inputStream)
      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:
      Flux<Message<byte[]>> representing output stream

    • clientStream

      public static org.springframework.messaging.Message<byte[]> clientStream(reactor.core.publisher.Flux<org.springframework.messaging.Message<byte[]>> inputStream)
      Utility method to support client-side streaming interaction. Will connect to gRPC server using default host/port, otherwise use clientStream(String, int, Flux) method.
      Parameters:
      inputStream - FluxMessage<byte[]>> representing input stream.
      Returns:
      Message<byte[]> representing output

    • clientStream

      public static org.springframework.messaging.Message<byte[]> clientStream(String host, int port, reactor.core.publisher.Flux<org.springframework.messaging.Message<byte[]>> inputStream)

      port - gRPC server port
      inputStream - FluxMessage<byte[]>> representing input stream
      Returns:
      Message<byte[]> representing output
