Class 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.
