All Implemented Interfaces:

ChannelHandler, ChannelInboundHandler

public class Socks4ServerDecoder
extends ReplayingDecoder<io.netty.handler.codec.socksx.v4.Socks4ServerDecoder.State>

Decodes a single Socks4CommandRequest from the inbound ByteBufs. On successful decode, this decoder will forward the received data to the next handler, so that other handler can remove this decoder later. On failed decode, this decoder will discard the received data, so that other handler closes the connection later.
