Class XrootdAuthenticationHandler

java.lang.Object

org.jboss.netty.channel.SimpleChannelUpstreamHandler

org.dcache.xrootd.core.XrootdAuthenticationHandler

All Implemented Interfaces:

org.jboss.netty.channel.ChannelHandler, org.jboss.netty.channel.ChannelUpstreamHandler

public class XrootdAuthenticationHandler
extends org.jboss.netty.channel.SimpleChannelUpstreamHandler

Netty handler implementing Xrootd kXR_login and kXR_auth. 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.
