Interface Summary
Interface	Description
AccessLog	Intended for use by a `Valve` to indicate that the `Valve` provides access logging.
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.
CredentialHandler	This interface is used by the `Realm` to compare the user provided credentials with the credentials stored in the `Realm` for that user.
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 `User`s in a `UserDatabase`.
Host	A Host is a Container that represents a virtual host in the Catalina servlet engine.
InstanceListener	Deprecated Will be removed in 8.5.x onwards
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 Context.
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.
StoreManager	PersistentManager would have been a better name but that would have clashed with the implementation name.
ThreadBindingListener	Callback for establishing naming association when entering the application scope.
TomcatPrincipal	Defines additional methods implemented by `Principal`s created by Tomcat's standard `Realm` implementations.
TrackedWebResource
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.
WebResource	Represents a file or directory within a web application.
WebResourceRoot	Represents the complete set of resources for a web application.
WebResourceSet	Represents a set of resources that are part of a web application.
Wrapper	A Wrapper is a Container that represents an individual servlet definition from the deployment descriptor of the web application.

Class Summary
Class	Description
ContainerEvent	General event for notifying listeners of significant changes on a Container.
Globals	Global constants that are applicable to multiple packages within Catalina.
InstanceEvent	Deprecated Will be removed in 8.5.x onwards
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.
