 transform a  Serializableobject into a byte buffer and
 vice versa. | 
| io.netty.handler.codec.socksx | Encoder, decoder and their related message types for SOCKS protocol. | 
| io.netty.handler.codec.socksx.v4 | Encoder, decoder and their related message types for SOCKSv4 protocol. | 
| io.netty.handler.codec.socksx.v5 | Encoder, decoder and their related message types for SOCKSv5 protocol. | 
| io.netty.handler.codec.spdy | Encoder, decoder, session handler and their related message types for the SPDY protocol. |
