Class Socks5PrivateAuthResponseDecoder

java.lang.Object

io.netty.channel.ChannelHandlerAdapter

io.netty.channel.ChannelInboundHandlerAdapter

io.netty.handler.codec.ByteToMessageDecoder

io.netty.handler.codec.socksx.v5.Socks5PrivateAuthResponseDecoder

All Implemented Interfaces:

ChannelHandler, ChannelInboundHandler

public final class Socks5PrivateAuthResponseDecoder
extends ByteToMessageDecoder

Decodes a single Socks5PrivateAuthResponse from the inbound ByteBufs. On successful decode, this decoder will forward the received data to the next handler, so that other handler can remove or replace this decoder later. On failed decode, this decoder will discard the received data, so that other handler closes the connection later.

The default format follows a simple structure:

• 1 byte: version (must be 1)
• 1 byte: status (0x00 for success, 0xFF for failure)

For custom private authentication protocols, you can:

• Create a new decoder implementing ByteToMessageDecoder or similar
• Implement the Socks5PrivateAuthResponse interface or extend DefaultSocks5PrivateAuthResponse
• Create a custom handler chain to process the authentication responses

               throws 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:

Exception - is thrown if an error occurs
