I'm not sure that you well understand my question. I probably poorly 
explained.

I'm building a library that'll be able to transform any object into an 
HashMap<string, string> associating the name of the property with its 
value as a string.
In the code I presently have, I can do this with basic types like int, 
string, etc. But I would like to get all the elements of a 
Gee.Collection. I can do this by using it's iterator property, but even 
if I know how to enumerate them and how to get their type, I don't know 
how to dynamically create a new instance of this type and convert en 
element of the collection (which I have as an Object) to this type. I 
hope it's clearer now.
