    • handler

      public GrpcReadStream<T> handler(Handler<T> handler)
      Description copied from interface: ReadStream

    • pause

      public GrpcReadStream<T> pause()
      Description copied from interface: ReadStream
      Pause the ReadStream, it sets the buffer in fetch mode and clears the actual demand.

      Resume reading, and sets the buffer in flowing mode.

      If the ReadStream has been paused, reading will recommence on it.

      Specified by:
      resume in interface ReadStream<T>
      Returns:
      a reference to this, so the API can be used fluently

    • fetch

      public GrpcReadStream<T> fetch(long l)
      Description copied from interface: ReadStream
      Fetch the specified amount of elements. If the ReadStream has been paused, reading will recommence with the specified amount of items, otherwise the specified amount will be added to the current stream demand.
      Specified by:
      fetch in interface ReadStream<T>
      Parameters:
      l -

      a reference to this, so the API can be used fluently

    • endHandler

      public GrpcReadStream<T> endHandler(Handler<Void> handler)
      Description copied from interface: ReadStream

      Parameters:
      handler -
      Returns:
      a reference to this, so the API can be used fluently

    • last

      public Future<T> last()

      Returns:
      the last element of the stream

    • end

      public Future<Void> end()
      Returns:
      a future signaling when the response has been fully received successfully or failed

    • rxEnd

      public Completable rxEnd()
      Returns:
      a future signaling when the response has been fully received successfully or failed

    • invalidMessageHandler

      public GrpcReadStream<T> invalidMessageHandler(Handler<InvalidMessageException> handler)
      Set a message handler that is reported with invalid message errors.

      Warning: setting this handler overwrite the default handler which takes appropriate measure when an invalid message is encountered such as cancelling the stream. This handler should be set when control over invalid messages is required.

      Parameters:
      handler - the invalid message handler
      Returns:
      a reference to this, so the API can be used fluently
