You can specify them in your forward header, and not in your implementation
header. That's what I do for poolfwd.hpp:
//map_fwd.hpp
namespace std {
template <class Key,
class T,
class Compare = std::less<T>,
class Alloc = std::allocator<T> >
class multimap;
}
//map.hpp
namespace std {
template <class Key,
class T,
class Compare,
class Alloc>
class multimap { ... };
}
//some client .hpp file
#include "map_fwd.hpp"
class map_tester {
//map pointer can use a forward declaration
std::multimap<int, int> * mmapPtr_;
};
