sorting - scala sort indexedseq in place

Question

How do you sort an IndexedSeq in place in scala? Where's the API function?

Answer 1

Currently there is nothing to sort them in-place.

If you really need that it would be possible to convert the IndexedSeq to an Array[AnyRef] and use Arrays.sort from Java (you have to cast to Array[AnyRef], because Scala's arrays are not covariant like Java's).

Interestingly a few weeks ago there was a discussion about adding in-place versions of operation like map, filter and sort to Scala's mutable collections.

I hope after the 2.9 release of parallel collections this could be the next work item on the list to further improve Scala's collection.

It doesn't hurt if people would raise their voice in support of it (or supply a working implememtation) :-).
