reversed

reversed example

Syntax	Code
Pipe	`rng \| boost::adaptors::reversed`
Function	`boost::adaptors::reverse(rng)`

Returns: A range whose iterators behave as if they were the original iterators wrapped in reverse_iterator.
Range Category: Bidirectional Range
Range Return Type: boost::reversed_range<decltype(rng)>
Returned Range Category: The range category of rng.

reversed example

#include <boost/range/adaptor/reversed.hpp>
#include <boost/range/algorithm/copy.hpp>
#include <boost/assign.hpp>
#include <iterator>
#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 would produce the output:

9,8,7,6,5,4,3,2,1,
