Re: [Cppcms-users] [template request] foreach reverse

[Artyom B. <art...@ya...>]

Hi,


Why wouldn't you just use reverse using Compare map key?

struct mycomp {
   bool operator(int x,int y)
   {
        return x > y;

   }

};


std::map<int,std::string,mycomp> revmap;


But generally it is not a problem to add such things 

to template system.

I'll take a look on it.

(If you can send me a patch it will be even better you need just
 to add some kind reverse option to foreach and replace begin(), end()
 with rbegin() and rend())
