Hi, I was wondering it is currently possible to give ptr_vector a custom deleter? This could simply be in the form of a functor. If this feature does not exist, would it be hard to add? For example, you could do this: namespace boost { namespace detail { template< typename t_type > struct default_deleter { void operator() ( t_type* ptr ) { delete ptr; } }; } template< typename t_type, typename t_deleter = detail::default_deleter<t_type> > class ptr_vector { private: std::vector<t_type*> m_pointers; public: ~ptr_vector() { std::for_each( m_pointers.begin(), m_pointers.end(), t_deleter() ); } }; }
