@Exported public class UnixNumericGroupPrincipal extends Object implements Principal, Serializable
This class implements the Principal interface
and represents a user's Unix group identification number (GID).
Principals such as this UnixNumericGroupPrincipal
may be associated with a particular Subject
to augment that Subject with an additional
identity. Refer to the Subject class for more information
on how to achieve this. Authorization decisions can then be based upon
the Principals associated with a Subject.
