| /** |
| * A {@code SecurityManager} executes all security operations for <em>all</em> Subjects (aka users) across a |
| * single application. |
| * <p/> |
| * The interface itself primarily exists as a convenience - it extends the {@link org.apache.shiro.authc.Authenticator}, |
| * {@link Authorizer}, and {@link SessionManager} interfaces, thereby consolidating |
| * these behaviors into a single point of reference. For most Shiro usages, this simplifies configuration and |
| * tends to be a more convenient approach than referencing {@code Authenticator}, {@code Authorizer}, and |
| * {@code SessionManager} instances separately; instead one only needs to interact with a single |
| * {@code SecurityManager} instance. |
| * <p/> |
| * In addition to the above three interfaces, this interface provides a number of methods supporting |
| * {@link Subject} behavior. A {@link org.apache.shiro.subject.Subject Subject} executes |
| * authentication, authorization, and session operations for a <em>single</em> user, and as such can only be |
| * managed by {@code A SecurityManager} which is aware of all three functions. The three parent interfaces on the |
| * other hand do not 'know' about {@code Subject}s to ensure a clean separation of concerns. |
| * <p/> |
| * <b>Usage Note</b>: In actuality the large majority of application programmers won't interact with a SecurityManager |
| * very often, if at all. <em>Most</em> application programmers only care about security operations for the currently |
| * executing user, usually attained by calling |
| * {@link org.apache.shiro.SecurityUtils#getSubject() SecurityUtils.getSubject()}. |
| * <p/> |
| * Framework developers on the other hand might find working with an actual SecurityManager useful. |
| * |
| * @see org.apache.shiro.mgt.DefaultSecurityManager |
