Interface Realm

All Known Implementing Classes:
RealmBase
public interface Realm

A Realm is a read-only facade for an underlying security realm used to authenticate individual users, and identify the security roles associated with those users. Realms can be attached at any Container level, but will typically only be attached to a Context, or higher level, Container.
