    • write

      public Future<Void> write(T data)
      Write some data to the stream.

      The data is usually put on an internal write queue, and the write actually happens asynchronously. To avoid running out of memory by putting too much on the write queue, check the WriteStream.writeQueueFull() method before writing. This is done automatically if using a .

      When the data is moved from the queue to the actual medium, the returned will be completed with the write result, e.g the future is succeeded when a server HTTP response buffer is written to the socket and failed if the remote client has closed the socket while the data was still pending for write.

      Specified by:
      write in interface WriteStream<T>
      Parameters:
      data - the data to write
      Returns:
      a future completed with the write result

      Returns:
      a future completed with the result

    • end

      public Future<Void> end(T data)
      Same as WriteStream.end() but writes some data to the stream before ending.
      Specified by:
      end in interface WriteStream<T>
      Parameters:
      data - the data to write
      Returns:
      a future completed with the result

    • rxEnd

      public Completable rxEnd(T data)

      rxEnd in interface WriteStream<T>
      Parameters:
      data - the data to write
      Returns:
      a future completed with the result

    • writeQueueFull

      public boolean writeQueueFull()
      This will return true if there are more bytes in the write queue than the value set using setWriteQueueMaxSize(int)
      Specified by:
      writeQueueFull in interface WriteStream<T>
      Returns:
      true if write queue is full

    • headers

      public MultiMap headers()
      Returns:
      the to reader metadata headers

    • encoding

      public GrpcWriteStream<T> encoding(String encoding)

      Set the stream encoding, e.g. identity or gzip,

      • The encoding must be set before sending any message, otherwise identity will be used.
      • The encoding should also match the opposite endpoint expectations.
      Parameters:
      encoding - the target message encoding
      Returns:
      a reference to this, so the API can be used fluently

    • format

      public GrpcWriteStream<T> format(WireFormat format)
      Set the stream format, e.g. proto or json. It must be called before sending any message, otherwise proto will be used.
      Parameters:
      format - the message format
      Returns:
      a reference to this, so the API can be used fluently

    • exceptionHandler

      public GrpcWriteStream<T> exceptionHandler(Handler<Throwable> handler)
      Description copied from interface: WriteStream
      Set an exception handler on the write stream.
      Specified by:
      exceptionHandler in interface StreamBase
      Specified by:
      exceptionHandler in interface WriteStream<T>
      Parameters:
      handler - the exception handler
      Returns:
      a reference to this, so the API can be used fluently

    • setWriteQueueMaxSize

      public GrpcWriteStream<T> setWriteQueueMaxSize(int i)
      Description copied from interface: WriteStream
      Set the maximum size of the write queue to maxSize. You will still be able to write to the stream even if there is more than maxSize items in the write queue. This is used as an indicator by classes such as Pipe to provide flow control.

      The value is defined by the implementation of the stream, e.g in bytes for a NetSocket, etc...

      Specified by:
      setWriteQueueMaxSize in interface WriteStream<T>
      Parameters:
      i - the max size of the write stream
      Returns:
      a reference to this, so the API can be used fluently

    • drainHandler

      public GrpcWriteStream<T> drainHandler(Handler<Void> handler)
      Description copied from interface: WriteStream
      Set a drain handler on the stream. If the write queue is full, then the handler will be called when the write queue is ready to accept buffers again. See Pipe for an example of this being used.

      The stream implementation defines when the drain handler, for example it could be when the queue size has been reduced to maxSize / 2.

      Specified by:
      drainHandler in interface WriteStream<T>
      Parameters:
      handler - the handler
      Returns:
