Re: Seeming JAX-RS mistake

[Sergey Beryozkin]

Hi Benson

This interface is meant to be used with types like JAXBContext or (JAXB) 
Marshaller, I think it was introduced to let users overcome the issues with the 
existing JAXB releases, for some specific types be handled by custom context 
providers. For ex, JAXB providers would check if ContextResolver<JAXBContext> 
was registered and then, say, ContextResolver.getContext(Foo.class) will be 
called. 
I think that in CXF if it were say Collection<Foo> then a registered 
ContextResolver<JAXBContext>, if any, would not be asked for a JAXBContext for 
Collection<Foo> but for Foo only

cheers, Sergey

  This can't work right for generic types (like collections), since it doesn't 
use java.lang.reflect.Type.

  public interface ContextResolver<T> {

      /**
       * Get a context of type <code>T</code> that is applicable to the supplied
       * type.
       * @param type the class of object for which a context is desired 
       * @return a context for the supplied type or <code>null</code> if a 
       * context for the supplied type is not available from this provider.
       */
      T getContext(Class<?> type);
  }
