Item's depth in ArrayCollection

Question

is it somehow possible to get item's depth in ArrayCollection?

Answer 1

here is my code...

public function getItemNestLevel(needle:Object, haystack:Object, level:Number = 0):Number
    {
        //iterate through items
        for each (var item:Object in haystack)
        {
            if (item == needle)
            {
                return level;
            }

            //iterate through item's properties
            for each (var child:Object in item)
            {
                if (child is Array || child is ArrayCollection)
                {
                    var lvl:Number = level + 1;
                    var num:Number = getItemNestLevel(needle, child, lvl);
                    if (num >= 0)
                    {
                        return num;
                    }
                }
            }
        }
        return -1;
    }
