Question

In AS3, Array.sort() took some nice sorting options like:

• Array.DESCENDING – sorts the array big to small
• Array.RETURNINDEXEDARRAY – returns an array of indices so you can track which item got sorted where

But sadly Vector<T>.sort() does not support these features, and simply takes a compareFunction:Function argument so you can write your own sorting logic.

Is there any other way to quickly get a sorted indexed-array of a vector?

Answer 1

RETURNINDEXEDARRAY does not work in Flash Player 10+. It just returns the same original Vector<Number>.

Unlike an Array, RETURNINDEXEDARRAY option is ignored for the Vector.sort() method. The returned Vector object is always the reference of the original object.
