Examples of PrincipalCollection

org.apache.shiro.subject.PrincipalCollection
A collection of all principals associated with a corresponding {@link Subject Subject}. A principal is just a security term for an identifying attribute, such as a username or user id or social security number or anything else that can be considered an 'identifying' attribute for a {@code Subject}.
A PrincipalCollection organizes its internal principals based on the {@code Realm} where they came from when theSubject was first created. To obtain the principal(s) for a specific Realm, see the {@link #fromRealm} method. Youcan also see which realms contributed to this collection via the {@link #getRealmNames() getRealmNames()} method. @author Les Hazlewood @see #getPrimaryPrincipal() @see #fromRealm(String realmName) @see #getRealmNames() @since 0.9
