-| [transform] | <code>function</code> | a custom transformation function for stored values; defaults to     the identity function; The first argument is the value to clone.     If it is a vertex value, the third argument is the vertex key.     If it is an edge value, the third and fourth argument are the     `from` and `to` keys respectively. (So you can test the fourth     argument to distinguish the two cases.) |
