 org.apache.catalina.valves.ValveBase
org.apache.catalina.authenticator.AuthenticatorBase
All known Subclasses: org.apache.catalina.authenticator.DigestAuthenticator, org.apache.catalina.authenticator.BasicAuthenticator, org.apache.catalina.authenticator.NonLoginAuthenticator, org.apache.catalina.authenticator.SSLAuthenticator, org.apache.catalina.authenticator.FormAuthenticator,
| AuthenticatorBase | | abstract public class AuthenticatorBase extends ValveBase implements Authenticator,Lifecycle(Code) | | Basic implementation of the Valve interface that enforces the
<security-constraint> elements in the web application
deployment descriptor. This functionality is implemented as a Valve
so that it can be ommitted in environments that do not require these
features. Individual implementations of each supported authentication
method can subclass this base class as required.
USAGE CONSTRAINT: 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.
USAGE CONSTRAINT: This Valve is only useful when processing HTTP
requests. Requests of any other type will simply be passed through.
