public class UnixNumericGroupPrincipal extends Object implements Principal, Serializable
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
.
