  - doWriteSingle
```
protected int doWriteSingle(io.netty.channel.ChannelOutboundBuffer in)
                     throws Exception
```
    Attempt to write a single object.
    Parameters:
    
    in - the collection which contains objects to write.
    
    Returns:
    The value that should be decremented from the write quantum which starts at ChannelConfig.getWriteSpinCount(). The typical use cases are as follows:
    
    0 - if no write was attempted. This is appropriate if an empty ByteBuf (or other empty content) is encountered
    
    1 - if a single call to write data was made to the OS
    
    ChannelUtils.WRITE_STATUS_SNDBUF_FULL - if an attempt to write data was made to the OS, but no data was accepted
    Throws:
    
    Exception - If an I/O error occurs.
