public interface Context
Provides an operation for obtaining contextual instances with a particular scope 
 of any contextual type. Any instance of Context is called a context object.
The context object is responsible for creating and destroying contextual instances 
 by calling operations of Contextual. In particular, 
 the context object is responsible for destroying any contextual instance it creates by 
 passing the instance to 
 Contextual.destroy(Object, CreationalContext). A 
 destroyed instance must not subsequently be returned by get().
 The context object must pass the same instance of 
 CreationalContext to Contextual.destroy() 
 that it passed to Contextual.create() when it created the instance.
A custom context object may be registered with the container using
 AfterBeanDiscovery.addContext(Context).
