Hi all,<br><br>I need to store in a class an object which type is within a predefined set. As I would like to avoid the overhead of virtual functions, I am wondering if variant could help me. Moreover, I would like to know what is the runtime cost of using such a type (instead of base class pointers), and the cost of the apply_visitor.<br>

<br>Hope you could help.<br><br>Regards,<br><br>Olivier<br>
