Make my C++ Class iterable via BOOST_FOREACH

Question

I have a class which I want to expose a list of structs (which just contain some integers). I don\'t want the outside to modify these data, just iterate over it and read the

Answer 1

If your collection type presents a standard container interface, you don't need to do anything to make BOOST_FOREACH work with your type. In other words, if your type has iterator and const_iterator nested typedefs, and begin() and end() member functions, BOOST_FOREACH already knows how to iterate over your type. No further action is required.
