/**
 * Immediate is a scope that operates like {@link javax.inject.Singleton} scope, except that instances are created as soon as their
 * corresponding {@link Descriptor}s are added.  When the corresponding {@link Descriptor} is removed from the 
 * locator the Immediate scope service is destroyed.  In particular Immediate scope services are not destroyed if
 * the {@link ServiceHandle#destroy()} method is called.  Care should be taken with the services injected into
 * an immediate service, as they also become virtual immediate services
 * 

* The Immediate scope is not automatically handled by a new ServiceLocator. In order to enable the Immediate scope * the user can either add an implementation of {@link Context} which handles it or it can use the * {@link org.glassfish.hk2.utilities.ServiceLocatorUtilities#enableImmediateScope(ServiceLocator)} method. * * @author jwells * */ @Documented @Retention(RUNTIME) @Scope @Target( { TYPE, METHOD }) public @interface Immediate { }
