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.

$iter->set ($from)
Set the contents of $iter. $from can be either another Gtk2::TreeIter or an "internal" arrayref form as above. Often you create a new iter instead of modifying an existing one, but "set" lets you to implement things in the style of the "remove" method of Gtk2::ListStore and Gtk2::TreeStore. A set can also explicitly invalidate an iter by zapping its stamp, so nobody can accidentally use it again. $iter->set ([0,0,undef,undef]);

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.
