Class BasicUser

java.lang.Object
  org.mmbase.security.BasicUser

All Implemented Interfaces:

Serializable, Comparable<Object>, UserContext

public class BasicUser
extends Object
implements UserContext, Comparable<Object>

A UserContext object is the result of an authentication, on which authorization can be based. Normally your authorization/authentication implementation will also provide an extension to this class. This default implementation is the most simple one, actually implementing 'no authorization' (because the rank is fixed to 'administrator'). This class is not necessarily also the container class for the client's credentials, although this is possible.
