Hi all..
I'm not sure whether my comment is help you or not, but I ever thinking about
this some time ago, and may be could be archived by something like:
public class Foo<T> {
private Class<T> clazz;
@Inject
public Foo(Class<T> c) {
this.clazz = c;
}
}
And by using custom qualifier, creating instance of Foo is just like:
@InjectConstructor(Blah.class)
private Foo<Blah> foo;
Am I missing something?
Thanks,
xsalefter
