Re: [Boost-users] [multi-index] member arguments [Was: how to use inheritmember as index]

Filip Konvi?ka ha escrito: [...]

I use this template in my code:

template<typename T> struct get_pointer_to_member_details;

template struct get_pointer_to_member_details { typedef Class class_type; typedef Member member_type; };

Using this, you can write (and I do) something like

template<typename MemberPointerType> struct member { MemberPointerType pMember; typedef typename get_pointer_to_member_details<MemberPointerType>::class_type class_type; typedef typename get_pointer_to_member_details<MemberPointerType>::member_type result_type;

member(MemberPointerType pMember) : pMember(pMember) {} // ... }

I wonder then, is it MSVC 8 that allows something non-standard, or is it OK? I think I tried with recent gcc as well and it worked...

Your code is fine, but it does not do what boost::multi_index::member is meant to do, namely accepting the pointer-to-member as a template parameter --rather, you're taking it as a runtime variable in construction time. Joaquín M López Muñoz Telefónica, Investigación y Desarrollo
