I didn't manage to make it work with references. Maybe someone else can help us out here?

Why are you using a vector of pointers? I prefer using a vector of objects, unless there is a good reason to use pointers (e.g., objects are HUGE and relocations would be too expensive, or I need polymorphism). If I really need to use pointers, I use a vector of shared_ptr or boost::ptr_vector.

You could do something like this:

but you'd have to change ObjectB::Apply(ObjectA&) to ObjectB::Apply(ObjectA*), I didn't manage to make it work with references. Maybe someone else can help us out here?
std::for_each(av.begin(), av.end(), [=] (ObjectA* a) { Apply(a); } );Quote:Original post by Chrominium
I am still getting my head around boost and binds as I have heard that doing your own vector loops is inefficient compared to the std algorithm.
