Interface Summary |
| 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. |
| Connector |
A Connector is a component responsible receiving requests from,
and returning responses to, a client application. |
| 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 applicaiton, in the Catalina servlet engine.
|
| Deployer |
A Deployer is a specialized Container into which web applications
can be deployed and undeployed. |
| Engine |
An Engine is a Container that represents the entire Catalina servlet
engine. |
| Host |
A Host is a Container that represents a virtual host in the
Catalina servlet engine. |
| HttpRequest |
An HttpRequest is the Catalina internal facade for an
HttpServletRequest that is to be processed, in order to
produce the corresponding HttpResponse. |
| HttpResponse |
An HttpResponse is the Catalina-internal facade for an
HttpServletResponse that is to be produced,
based on the processing of a corresponding HttpRequest. |
| 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.
|
| Logger |
A Logger is a generic interface for the message and exception
logging methods of the ServletContext interface. |
| Manager |
A Manager manages the pool of Sessions that are associated with a
particular Container. |
| Mapper |
Interface defining methods that a parent Container may implement to select
a subordinate Container to process a particular Request, optionally
modifying the properties of the Request to reflect the selections made.
|
| 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. |
| Request |
A Request is the Catalina-internal facade for a
ServletRequest that is to be processed, in order to
produce the corresponding Response. |
| Response |
A Response is the Catalina-internal facade for a
ServletResponse that is to be produced,
based on the processing of a corresponding Request. |
| Server |
A Server represents one convenient way to package a set of
Connectors associated with a particular 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.
|
| Valve |
A Valve is a request processing component associated with a
particular Container. |
| ValveContext |
A ValveContext is the mechanism by which a Valve can trigger the
execution of the next Valve in a Pipeline, without having to know anything
about the internal implementation mechanisms. |
| Wrapper |
A Wrapper is a Container that represents an individual servlet
definition from the deployment descriptor of the web application. |
