/**
* An annotation used to specify server resources with enforced authentication and resources accessible without authentication.
*
* The following sample shows examples of use of {@link Authenticated} annotation in a JAX-RS/Jersey application:
*
*
* @Authenticated
* @ApplicationPath("myApp")
* public class SecuredApplication extends javax.ws.rs.core.Application { ... }
*
* @Authenticated(false)
* @Path("/")
* public class PublicResource {
* @GET
* public String getResourceContent() { ... }
*
* // Only authenticated users can update the content of the public resource
* @Authenticated
* @PUT
* public Response setNewResourceContent(String content) { ... }
* }
*
*
* Authenticated annotation is not cumulative - e.g. if you define this annotation on a resource method, it will take
* ALL values from this instance of Authenticated (so if you want to use a custom authentication provider, you must define it
* again in each Authenticated instance).
