| /** |
| * Basic implementation of the <b>Valve</b> interface that enforces the |
| * <code><security-constraint></code> elements in the web application |
| * deployment descriptor. This functionality is implemented as a Valve |
| * so that it can be omitted in environments that do not require these |
| * features. Individual implementations of each supported authentication |
| * method can subclass this base class as required. |
| * <p> |
| * <b>USAGE CONSTRAINT</b>: When this class is utilized, the Context to |
| * which it is attached (or a parent Container in a hierarchy) must have an |
| * associated Realm that can be used for authenticating users and enumerating |
| * the roles to which they have been assigned. |
| * <p> |
| * <b>USAGE CONSTRAINT</b>: This Valve is only useful when processing HTTP |
| * requests. Requests of any other type will simply be passed through. |
