Re: [Boost-users] Possible is_shared_ptr type_traits function

I am writing a template class that processes several types. However my problem is that when the type of the template is boost::shared_ptr<P> (and only in that case) I need to do a boost::dynamic_pointer_cast<P> inside a method.

So, I searched boost::type_traits library but could not find anything to detect a shared_ptr type at compile time. I would appreciate any ideas of how this could be implemented.

Easy: not a traits class, but a function overload: template <class To, class From> To* my_cast(From* p) { return dynamic_cast<To*>(p); } template <class To, class From> shared_ptr<To> my_cast(shared_ptr<From> p) { return dynamic_pointer_cast<From>(p); } Then call my_cast<Target*>(p); rather than: dynamic_cast<Target*>(p); John.
