public member function

std::multimap::crbegin

const_reverse_iterator crbegin() const noexcept;
Return const_reverse_iterator to reverse beginning
Returns a const_reverse_iterator pointing to the last element in the container (i.e., its reverse beginning).

Parameters

none

Return Value

A const_reverse_iterator to the reverse beginning of the sequence.

Member type const_reverse_iterator is a reverse bidirectional iterator type that points to a const element (see multimap member types).

// multimap::crbegin/crend
#include <iostream>
#include <map>

int main ()
{
  std::multimap<char,int> mymultimap = { {'x',100}, {'y',200}, {'x',300} };

  // print content:
  std::cout << "mymultimap backwards:";
  for (auto rit = mymultimap.crbegin(); rit != mymultimap.crend(); ++rit)
    std::cout << " [" << rit->first << ':' << rit->second << ']';
  std::cout << '\n';

  return 0;
}


Output:
mymultimap backwards: [y:200] [x:300] [x:100]

Complexity

Constant.

Iterator validity

No changes.

Data races

The container is accessed.
No contained elements are accessed by the call, but the iterator returned can be used to access them. 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.
