Class NobodyPrincipal

java.lang.Object
  extended by org.jboss.security.NobodyPrincipal
All Implemented Interfaces:
Comparable, Principal

public class NobodyPrincipal
extends Object
implements Comparable, Principal

An implementation of Principal and Comparable that represents no role. Any Principal or name of a Principal when compared to an NobodyPrincipal using equals or compareTo will always be found not equal to the NobodyPrincipal. Note that this class is not likely to operate correctly in a collection since the hashCode() and equals() methods are not correlated.
