[Boost-users] How to forward to a list of boost::function?

Hi all, I have a class: template<typename function_type> class function_vector { private: std::vector<boost::function<function_type> > functions; }; I want to write an operator() for this template class that takes all the arguments necessary to invoke a function of type function_type. When called, it should call each function in the functions field. How do I do this? I think Boost.Signals2 does something like this, but I can't work out how it is done. Cheers, -John
