Re: [boost] boost::function overhead?

boost::function doesn't use virtual functions, but the effect is the same. boost::function adds one additional indirect call through a function pointer.

Sorry for the inaccurate response. Out of curiousity, is this technique described anywhere (other than the code)? It's hard to imagine the way to erase the type of a functor without some kind of a polymorphic adaptor... Does this technique have an advantage over the one with a virtual function call?
