Pete Muir moved WELDX-189 to SOLDER-23:
---------------------------------------
Project: Seam Solder (was: Weld Extensions)
Key: SOLDER-23 (was: WELDX-189)
Affects Version/s: (was: 1.0.0.Beta1)
Fix Version/s: 1.0.0.Beta2
(was: 1.0.0.Beta2)
> Provide utility to extract type parameter from Instance
> -------------------------------------------------------

> Key: SOLDER-23
> URL: https://jira.jboss.org/browse/SOLDER-23
> Project: Seam Solder
> Issue Type: Feature Request
> Reporter: Dan Allen
> Priority: Minor
> Fix For: 1.0.0.Beta2
>
>
> When discovering injection points, a type of Instance<T> is effectively the
> same as discovering a type T. You don't want to create a producer method for
> an Instance, for instance, hence why you want to figure out what T is. Thus,
> it's common to want to extract the type parameter from Instance. Having a
> utility would be convenient.
> Here's an example that collects the actual bean types (extracting from the
> Instance type parameter if necessary)
> Set<Type> types = new HashSet<Type>();
> for (InjectionPoint ip : event.getInjectionTarget().getInjectionPoints())
> {
> types.add(Reflections.getActualType(ip.Type()));
> }
> Here's the utility:
> private static Type getActualType(Type t)
> {
> if (t instanceof ParameterizedType && ((ParameterizedType)
> t).getRawType().equals(Instance.class))
> {
> return ((ParameterizedType) t).getActualTypeArguments()[0];
> }
> return t;
> }
