I was struggling to find the return type of range filtered/filter.
Here is a small working example (based from your documentation):
#include <boost/range/adaptor/filtered.hpp> #include <boost/range/algorithm/copy.hpp> #include <boost/assign.hpp> #include <iterator> #include <iostream> #include <vector> struct is_even { bool operator()( int x ) const { return x % 2 == 0; } }; int main(int argc, const char* argv[]) { std::vector<int> input {1,2,3,4,5,6,7,8,9}; boost::filtered_range<decltype(is_even()), decltype(input)> f_range = boost::adaptors::filter(input, is_even()); boost::copy(f_range, std::ostream_iterator<int>(std::cout, ",")); return 0; }
