treeiter = Gtk2::TreeIter->new_from_arrayref ($sv_iter)
Create a new Gtk2::TreeIter from the "internal" array reference representation used by custom Gtk2::TreeModel implementations. This is the complement to Gtk2::TreeIter::to_arrayref(), and is used when you need to create and return a new iter from a method that is not one of the Gtk2::TreeModelIface interface vfuncs. See "CREATING A CUSTOM TREE MODEL" in Gtk2::TreeModel for more information.

scalar = $iter->to_arrayref ($stamp)
Convert a boxed Gtk2::TreeIter reference into the "internal" array reference representation used by custom Gtk2::TreeModel implementations. This is necessary when you need to get to the data inside your iters in methods which are not the vfuncs of the Gtk2::TreeModelIface interface. The stamp must match; this protects the binding code from potential memory faults when attempting to convert an iter that doesn't actually belong to your model.
