Boost.Range

Range Adaptors

`reversed`

rng | boost::adaptors::reversed

boost::make_reversed_range( rng )

Returns: A range whose iterators behave as if they were the original iterators wrapped in reverse_iterator.
Range Category: BidirectionalRange

Example

        #include <boost/range/adaptor/reversed.hpp>
        #include <boost/range/algorithm/copy.hpp>
        #include <boost/assign.hpp>
        #include <algorithm>
        #include <iostream>
        #include <vector>
        
        int main(int argc, const char* argv[])
        {
            using namespace boost::adaptors;
            using namespace boost::assign;
            
            std::vector<int> input;
            input += 1,2,3,4,5,6,7,8,9;
            
            boost::copy(
                input | reversed,
                std::ostream_iterator<int>(std::cout, ","));
                
            return 0;
        }

This produces the output:
9,8,7,6,5,4,3,2,1
