      • writeByte

        public void writeByte​(int value)
        Description copied from interface: BsonOutput
        Write a single byte to the stream. The byte to be written is the eight low-order bits of the specified value. The 24 high-order bits of the value are ignored.

        Description copied from class: OutputBuffer
        Write the specified byte at the specified position.
        Specified by:
        write in class OutputBuffer
        absolutePosition - the position, which must be greater than equal to 0 and at least 4 less than the stream size
        value - the value to write. The 24 high-order bits of the value are ignored.
      • getPosition

        public int getPosition()

                 throws IOException
        Description copied from class: OutputBuffer
        Pipe the contents of this output buffer into the given output stream
        Specified by:
        pipe in class OutputBuffer

        Description copied from interface: BsonOutput
        Truncates this stream to the new position. After this call, both size and position will equal the new position.
        Specified by:
        truncateToPosition in interface BsonOutput
        Specified by:
        truncateToPosition in class OutputBuffer
        newPosition - the new position, which must be greater than or equal to 0 and less than the current size.
      • getByteBuffers

        public List<ByteBuf> getByteBuffers()
        Description copied from class: OutputBuffer
        Get a list of byte buffers that are prepared to be read from; in other words, whose position is 0 and whose limit is the number of bytes that should read.
