Re: [Vala] Personal iterable, collection, list classes

["Michael Lawrence" <mflawren fhcrc org>]

Are there any plans to include libgee within glib, as a separate module like GIO?

Hi Alessandro,

because you are wrapping an already iterable object
(your 'objects' property) you can do this very simply
by returning the iterator for that collection:

public class MyList : Object, Iterable<MyObject> {
 protected ArrayList<MyObject> objects;

 public Type get_element_type () {
   return typeof (MyObject);
 }

 public Gee.Iterator<MyObject> iterator () {
   return objects.iterator();
 }
}

...

foreach(MyObject m in my_list) {
 ...
}

best,
Dan
