io.netty.channel.ChannelInboundHandlerAdapter

org.dcache.xrootd.core.XrootdAuthenticationHandler

All Implemented Interfaces:

io.netty.channel.ChannelHandler, io.netty.channel.ChannelInboundHandler

public class XrootdAuthenticationHandler
extends io.netty.channel.ChannelInboundHandlerAdapter

Netty handler implementing Xrootd kXR_login, kXR_auth, and kXR_endsess. Delegates the authentication steps to an AuthenticationHandler. Rejects all other messages until login has completed. Note the difference between this class and AuthenticationHandler. The latter is part of a plugin implementing the core authentication logic whereas this class is a Netty handler. The class may be subclassed to override the authenticated method to add additional operations after authentication.
