Interface Summary |
AccessLog |
Intended for use by a Valve to indicate that the Valve
provides access logging. |
Authenticator |
An Authenticator is a component (usually a Valve or Container) that
provides some sort of authentication service. |
Cluster |
A Cluster works as a Cluster client/server for the local host
Different Cluster implementations can be used to support different
ways to communicate within the Cluster. |
Contained |
Decoupling interface which specifies that an implementing class is
associated with at most one Container instance. |
Container |
A Container is an object that can execute requests received from
a client, and return responses based on those requests. |
ContainerListener |
Interface defining a listener for significant Container generated events. |
ContainerServlet |
A ContainerServlet is a servlet that has access to Catalina
internal functionality, and is loaded from the Catalina class loader
instead of the web application class loader. |
Context |
A Context is a Container that represents a servlet context, and
therefore an individual web application, in the Catalina servlet engine. |
DistributedManager |
Interface implemented by session managers that do not keep a complete copy
of all sessions on the local node but do know where every session is. |
Engine |
An Engine is a Container that represents the entire Catalina servlet
engine. |
Executor |
|
Group |
Abstract representation of a group of User s in a
UserDatabase . |
Host |
A Host is a Container that represents a virtual host in the
Catalina servlet engine. |
InstanceListener |
Interface defining a listener for significant events related to a
specific servlet instance, rather than to the Wrapper component that
is managing that instance. |
Lifecycle |
Common interface for component life cycle methods. |
LifecycleListener |
Interface defining a listener for significant events (including "component
start" and "component stop" generated by a component that implements the
Lifecycle interface. |
Loader |
A Loader represents a Java ClassLoader implementation that can
be used by a Container to load class files (within a repository associated
with the Loader) that are designed to be reloaded upon request, as well as
a mechanism to detect whether changes have occurred in the underlying
repository. |
Manager |
A Manager manages the pool of Sessions that are associated with a
particular Container. |
Pipeline |
Interface describing a collection of Valves that should be executed
in sequence when the invoke() method is invoked. |
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. |
Role |
Abstract representation of a security role, suitable for use in
environments like JAAS that want to deal with Principals . |
Server |
A Server element represents the entire Catalina
servlet container. |
Service |
A Service is a group of one or more
Connectors that share a single Container
to process their incoming requests. |
Session |
A Session is the Catalina-internal facade for an
HttpSession that is used to maintain state information
between requests for a particular user of a web application. |
SessionListener |
Interface defining a listener for significant Session generated events. |
Store |
A Store is the abstraction of a Catalina component that provides
persistent storage and loading of Sessions and their associated user data. |
User |
Abstract representation of a user in a UserDatabase . |
UserDatabase |
Abstract representation of a database of User s and
Group s that can be maintained by an application,
along with definitions of corresponding Role s, and
referenced by a Realm for authentication and access control. |
Valve |
A Valve is a request processing component associated with a
particular Container. |
Wrapper |
A Wrapper is a Container that represents an individual servlet
definition from the deployment descriptor of the web application. |
