public interface Group extends Principal
Note that Group extends Principal. Thus, either a Principal or a Group can
be passed as an argument to methods containing a Principal parameter. For
example, you can add either a Principal or a Group to a Group object by
calling the object's
addMember method, passing it the
Principal or Group.
