[Vala] public class Foo : List<Bar>

[banjo <banjo actrix com>]

hi

I was trying to test whether this is allowed...

  public class Foo : List<Bar> {

...and got this error...



// valac --pkg gtk+-3.0 classtest.vala

public class NodeList : List<Strung> {
  public NodeList () { }
}

public class Strung {
  private string val;
  public Strung (string v) { this.val = v; }
  public string value () { return this.val; }
}

public static int main (string[] args) {
    NodeList list = new NodeList ();
    list.append ((Strung) "1. entry");
    list.append ((Strung) "2. entry");
    list.append ((Strung) "3. entry");

    unowned List<Strung> element = list.nth (2);
    stdout.printf ("list.nth (2) = \"%s\"\n", (string) 
element.data.value ());
    int pos = list.position (element);
    stdout.printf ("Position: list.position () = %d\n", pos);
    return 0;
}



bash$ valac --pkg gtk+-3.0 classtest.vala

... so i guess it isn't allowed?
