Re: [Boost-users] [boost::any] Using any as an abstract class container

Let's say i have a hierarchy of object that all inherits from a abse class called base_impl. Among those classes, most of them are tempalte that have large, complex type.

My idea was to use boost::any to store any of this classes' instances, any_cast them back to base_impl* and call one of the base_impl virtual method.

Why can't you return shared_ptr, e.g.?

I can't rely on stroing a pointer in the boost::any member. Any solution to this problem or am I doing something wrong.

boost::any_cast requires the type to match exactly. In Christ, Steven Watanabe
