[Boost-users] [fusion][mpl] How to make a vector of a vector of types

15 Mar 2007

      Hi there, subject probably sounds a bit strange but here is what I'm
trying to accomplish.

The problem description goes like this:

using namespace boost;
using namespace boost::fusion;

struct A;
struct B;
struct C;

int main()
{
   typedef vector< A, B, C > types;

   // how to translates typed into the following??

   typedef vector< std::vector<A>, std::vector<B>, std::vector<C> >
vector_of_types;

   return 0;
}

I'm looking for a generic approach to do this. To me it seems like it
should be possible by taking parts of the MPL lib, like
mpl::push_back, and parts of the fusion lib, like fusion::for_each.

Any ideas?

Thanks ahead,
Christian
