ChannelHandler
,ChannelInboundHandler
public class Socks4ClientDecoder extends ReplayingDecoder<Socks4ClientDecoder.State>
Decodes a singleSocks4CommandResponse
from the inboundByteBuf
s. 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.
