Reverse

Include <mln/core/ranges/view/reverse.hpp>

auto view::reverse(ReversibleRange r)

Parameters:

r – Input range

If the expression r.reversed() is valid, then it is returned. Otherwise, r must model the concept BidirectionalRange and the function returns ::ranges::view::reverse(rng). This view preserves the following properties:

Properties	r	reverse(r)
Segmented	X	X
Forward	X	X
Reversible	X	X
Bidirectional	X	X
Random Access	X	X
Contiguous	X	X
Writable	X	X

Examples

• Browse a box2d’s indexes reversly:

  mln::box2d box = {{0,0}, {2,3}};
  mln_foreach(auto p, ranges::view::reverse(box))
    std::cout << p << ",";
  

  Outputs:

  (1,2),(1,1),(1,0),(0,2),(0,1),(0,0),
