All Implemented Interfaces:

ChannelHandler ， ChannelInboundHandler
```
public class Socks5CommandRequestDecoder
extends ReplayingDecoder<io.netty.handler.codec.socksx.v5.Socks5CommandRequestDecoder.State>
```
从入站ByteBuf解码单个Socks5CommandRequest 。在成功解码时，该解码器会将接收到的数据转发到下一个处理程序，以便其他处理程序可以在稍后移除或替换此解码程序。解码失败时，该解码器将丢弃接收到的数据，以便其他处理程序稍后关闭连接。
