/**
* Identifies a type as being an actuator endpoint that provides information about the
* running application. Endpoints can be exposed over a variety of technologies including
* JMX and HTTP.
* <p>
* Most {@code @Endpoint} classes will declare one or more
* {@link ReadOperation @ReadOperation}, {@link WriteOperation @WriteOperation},
* {@link DeleteOperation @DeleteOperation} annotated methods which will be automatically
* adapted to the exposing technology (JMX, Spring MVC, Spring WebFlux, Jersey etc.).
* <p>
* {@code @Endpoint} represents the lowest common denominator for endpoints and
* intentionally limits the sorts of operation methods that may be defined in order to
* support the broadest possible range of exposure technologies. If you need deeper
* support for a specific technology you can either write an endpoint that is
* {@link FilteredEndpoint filtered} to a certain technology, or provide
* {@link EndpointExtension extension} for the broader endpoint.
