[Vala] Reflection : getting values in Gee.Collection

[Baptiste Gelez <gelezbaptiste openmailbox org>]

Hello everyone !

I would like to retrieve any property of an object. I presently use this
code :

HashMap<string, string> result = new HashMap<string, string> ();

foreach (ParamSpec spec in obj.get_class ().list_properties ()) {
 GLib.Value val = GLib.Value (typeof (string));
 obj.get_property (spec.get_nick (), ref val);
 result [spec.get_nick ()] = (string) val;
}

return result;

There is no problem when I'm getting "simple" values like int, string,
double, etc ... But I would like to be able to get all the elements of
Gee.Collection. Have you got any idea of how to do that ?

Thanks ! (And excuse me for possible English mistakes)
