public interface ItsNatUserData

This basic interface provides a user data registry. This registry is in no way used by the framework.

Most of ItsNat objects implement this interface to help the user to reduce the work of wiring user data with ItsNat objects.

User data registry methods are synchronized if this object is a ItsNatServletContext, ItsNatServlet, ItsNatServletConfig, ItsNatSession, MarkupTemplate or CometNotifier otherwise are unsynchronized.
