    • BootMessage

      public BootMessage(ByteBuffer buffer)
      Deserialise a boot message from a received message.
      Parameters:
      buffer - the buffer to read out of.

  • Method Details

    • addToBuffer

      public void addToBuffer(ByteBuffer buffer)
      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 big-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.
      Specified by:
      addToBuffer in interface SerializableMessage
      Parameters:
      buffer - The buffer to write into.
