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.
