| Interface | Description |
|---|---|
| AccessLog | |
| AsyncDispatcher | |
| 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 in memory 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
Users in a
UserDatabase. |
| GSSRealm | Deprecated
This will be removed in Tomcat 9 and integrated into
Realm. |
| 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.
|
| JmxEnabled |
This interface is implemented by components that will be registered with an
MBean server when they are created and unregistered when they are destroyed.
|
| Lifecycle |
Common interface for component life cycle methods.
|
| Lifecycle.SingleUse |
Marker interface used to indicate that the instance should only be used
once.
|
| 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. |
| SessionIdGenerator | |
| 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 | |
| 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.
|
| Class | Description |
|---|---|
| CatalinaFactory | Deprecated
There was no demand for this capability and it will be removed in
Tomcat 8.0.x
|
| ContainerEvent |
General event for notifying listeners of significant changes on a Container.
|
| Globals |
Global constants that are applicable to multiple packages within Catalina.
|
| InstanceEvent |
General event for notifying listeners of significant events related to
a specific instance of a Servlet, or a specific instance of a Filter,
as opposed to the Wrapper component that manages it.
|
| LifecycleEvent |
General event for notifying listeners of significant changes on a component
that implements the Lifecycle interface.
|
| SessionEvent |
General event for notifying listeners of significant changes on a Session.
|
| Enum | Description |
|---|---|
| LifecycleState |
The list of valid states for components that implement
Lifecycle. |
| Exception | Description |
|---|---|
| LifecycleException |
General purpose exception that is thrown to indicate a lifecycle related
problem.
