public member function
<map>

std::multimap::rend

      reverse_iterator rend();
const_reverse_iterator rend() const;
      reverse_iterator rend() nothrow;
const_reverse_iterator rend() const nothrow;
Return reverse iterator to reverse end
Returns a reverse iterator pointing to the theoretical element right before the first element in the multimap container (which is considered its reverse end).

The range between multimap::rbegin and multimap::rend contains all the elements of the container (in reverse order).

Parameters

none

Return Value

A reverse iterator to the reverse end of the sequence container.

If the multimap object is const-qualified, the function returns a const_reverse_iterator. Otherwise, it returns a reverse_iterator.

Member types reverse_iterator and const_reverse_iterator are reverse bidirectional iterator types pointing to elements. See multimap member types.

// multimap::rbegin/rend
#include <iostream>
#include <map>

int main ()
{
  std::multimap<char,int> mymultimap;

  mymultimap.insert (std::make_pair('x',10));
  mymultimap.insert (std::make_pair('y',20));
  mymultimap.insert (std::make_pair('y',150));
  mymultimap.insert (std::make_pair('z',9));

  // show content:
  std::multimap<char,int>::reverse_iterator rit;
  for (rit=mymultimap.rbegin(); rit!=mymultimap.rend(); ++rit)
    std::cout << rit->first << " => " << rit->second << '\n';

  return 0;
}


Output:
z => 9
y => 150
y => 20
x => 10

Complexity

Constant.

Iterator validity

No changes.

Data races

The container is accessed (neither the const nor the non-const versions modify the container).
No contained elements are accessed by the call, but the iterator returned can be used to access or modify elements. Concurrently accessing or modifying different elements is safe.

Exception safety

No-throw guarantee: this member function never throws exceptions.
The copy construction or assignment of the returned iterator is also guaranteed to never throw.
