- All Implemented Interfaces:
- Serializable,- Principal
 
 public class UnixNumericGroupPrincipal extends Object implements Principal, Serializable This class implements thePrincipalinterface and represents a user's Unix group identification number (GID).Principals such as this UnixNumericGroupPrincipalmay be associated with a particularSubjectto augment thatSubjectwith an additional identity. Refer to theSubjectclass for more information on how to achieve this. Authorization decisions can then be based upon the Principals associated with aSubject.- See Also:
