Hi, Is there any boost utility which statically determines if a template parameter is const or not? ( MPL library ?)
I need to design something like boost::sub_range, but little different (It will iterate over arbitrary sequence stored in a vector form, rather than a sequence stored in pair form). like, template<typename C> class index_range{ private: C* container_; std::vector<size_type> index_; }; container & index will be passed through constructor. Now if C is const container it will return const_reference etc.
Thus what is needed is something like, container_traits<const std::vector>::iterator is a const_iterator while container_traits<std::vector>::iterator is a iterator etc.
What is wrong with boost::range_iterator<C>::type ? -Thorsten
