AS3 Vector.sort() does not take sorting options?

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

Check out the documentation : http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/Vector.html#sort()

It is still possible to use those options but you have to pass them in as the first parameter instead of the compare function.

 myVector.sort(Array.DESCENDING|Array.RETURNINDEXEDARRAY);

Answer 2

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.
