Detailed Description

template<typename Coll, typename Pred, typename ValT = typename std::remove_cv<typename Coll::value_type>::type, typename IterT = typename Coll::iterator, typename SizeT = typename Coll::size_type>
struct herald::analysis::views::filtered_iterator_proxy< Coll, Pred, ValT, IterT, SizeT >

Now we create a version that selectively returns the underlying iterator's elements using filter_fn Use like:- myCollection is a collection with 14,16,19,45,66 in it (ints) filtered_iterator_proxy<> proxy(myCollection, in_range<int>(18,65)); while (proxy != std::end(myCollection)) { // Could also use !proxy.ended() std::cout << *proxy << std::endl; // prints ONLY 19 and 45 ++proxy; }
