Thanks, that worked now. I like the fusion::for_each loop, it's very handy!
Anyway, when I started this thread I actually had something else in my mind. As you can see the doSomething() is templated. I would like to create a type vector depending on the template parameter, here S. Is that possible?
I could image to have something like this ( beware bad pseudo code ):
template <class S> void doSomething( S& s ) { //create vector depending on S's length typedef fusion::vector<S::num_values> vec; // vector length
// add the members type to vec fusion::for_each_member( s, vec.add() );
// create boost tuple type out of vec fusion::make_tuple( vec ); }
Am I totally fantasying here? I think all the infomation are available at compile time.
Creating a type vector depending on the template parameter, S, is certainly OK. I'll have to ignore the "bad pseudo code" though ;) You have to do it another way. Tell me precisely what you wish to do and I may be able to provide an example. Actually, I am compiling a small set of simple use-case examples. You wouldn't mind if I use our first example, would you? Regards, -- Joel de Guzman http://www.boost-consulting.com http://spirit.sf.net
