struct IFactory
{	virtual boost:: intrusive_ptr<IClass> createIClass(
             const std::vector<boost::any> &) const = 0;
};

or even arguments by name:

struct IFactory
{	virtual boost:: intrusive_ptr<IClass> createIClass(
             const std::map<std::string, boost::any> &) const = 0;
};

Hi,

How factory can be used when derived classes need constructing with 
different args?

Could someone show an sample?

Thank you,
Vic
