[Adobe-source-devel] regular_object with value_t

[Ralph T. <ra...@gm...>]

Hi,

  I'm not sure if this is possible, but... is there a way to put an
instance of some class into a value_t and then later pull out
regular_interfaces on it? Something like this:

struct widget {
  // from View
  void display(const type_t&);
  // from Controller
  void monitor(monitor_fn_t);
  ...
};

value_t v(new widget());
any_view_t* view = v.get<any_view_t*>();
any_controller_t* controller = v.get<any_controller_t*>();

The problems I have where this would be useful are typically wrapping
an API that defines a type for "a group of objects that can be
enumerated" (which I would have to convert to an array_t) and provides
some special operations on the group type (so I'd also have to have
the specific group type available). Of course, I can also solve this
problem by providing a conversion function, but this seemed more
interesting :).

Thanks,
 Ralph
