  • Method Details

    • addToBuffer

      public void addToBuffer(ByteBuffer buffer)
      Description copied from interface: SerializableMessage
      Writes this message into the given buffer as a contiguous range of bytes. This is so that a message can be sent. Implementors may assume that the buffer has been configured to be little-endian and that its position is at the point where they should begin writing. Once it has finished, the position should be immediately after the last byte written by this method.

      Calling this method should not update the internal state of the message. It should be possible to add the message to multiple buffers without special precautions by the caller.

      Parameters:
      buffer - The buffer to write into.

    • getSCPResponse

      public abstract T getSCPResponse(ByteBuffer buffer) throws Exception
      Parse the response to this message.
      Parameters:
      buffer - The buffer to parse.
      Returns:
      The message response.
      Throws:
      Exception - If anything goes wrong with parsing.
