java.lang.Object
- com.sun.security.auth.UnixNumericUserPrincipal

All Implemented Interfaces:

Serializable, Principal
```
public class UnixNumericUserPrincipal
extends Object
implements Principal, Serializable
```
This class implements the Principal interface and represents a user's Unix identification number (UID).
Principals such as this UnixNumericUserPrincipal 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.
