Class Socks4ClientDecoder

java.lang.Object

io.netty.channel.ChannelHandlerAdapter

io.netty.channel.ChannelInboundHandlerAdapter

io.netty.handler.codec.ByteToMessageDecoder

io.netty.handler.codec.ReplayingDecoder<Socks4ClientDecoder.State>

io.netty.handler.codec.socksx.v4.Socks4ClientDecoder

All Implemented Interfaces:

ChannelHandler, ChannelInboundHandler

public class Socks4ClientDecoder
extends ReplayingDecoder<Socks4ClientDecoder.State>

Decodes a single Socks4CommandResponse 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.

decode

protected void decode(ChannelHandlerContext ctx,
 ByteBuf in,
 java.util.List<java.lang.Object> out)
               throws java.lang.Exception

Description copied from class: ByteToMessageDecoder

Decode the from one ByteBuf to an other. This method will be called till either the input ByteBuf has nothing to read when return from this method or till nothing was read from the input ByteBuf.

Specified by:

decode in class ByteToMessageDecoder

Parameters:

ctx - the ChannelHandlerContext which this ByteToMessageDecoder belongs to

in - the ByteBuf from which to read data

out - the List to which decoded messages should be added

Throws:

java.lang.Exception - is thrown if an error occurs

fail
