Interface PrincipalComparator
public interface PrincipalComparator
An object that implements the
java.security.Principal interface typically also implements this interface
to provide a means for comparing that object to a specified Subject.
The comparison is achieved via the implies method. The implementation of the implies method
determines whether this object "implies" the specified Subject. One example application of this method
may be for a "group" object to imply a particular Subject if that Subject belongs to the
group. Another example application of this method would be for "role" object to imply a particular
Subject if that Subject is currently acting in that role.
Although classes that implement this interface typically also implement the java.security.Principal
interface, it is not required. In other words, classes may implement the java.security.Principal
interface by itself, the PrincipalComparator interface by itself, or both at the same time.-
