Pointer sort won't work in my case. Ultimately I do have to reorder the entries in the container. Just consider the whole container is memory mapped to a file. Indeed, there are multiple memory mapped containers and the sort is determined by one of these. Basically each record consists of one entry in each container. I have written a random access iterator to use the standard sort but creating temp objects for these memory mapped records is expensive. My application is somewhat memory bound. By the way, I think what I want is a sort that minimize the use of temporary copies. Swap is likely the alternative, but I am open to other solutions. Russell Tim Rowe wrote:

One solution is to sort a set of pointers to the objects. Any sort routine that lets you specify a sort function will let you sort the pointers into the referenced objects' ordering.

I know this is kinda off topic.

I am trying to sort some objects which are expensive to copy. Does anyone know a sort implementation that uses neither copier nor assignment? The STLport version I have is using both. Worse, some routines are passing arguments as T instead of const T &. I did search boost and google but I couldn't find what I want.

Thanks in advance.
