public member function
<map>

std::multimap::cend

const_iterator cend() const noexcept;
Return const_iterator to end
Returns a const_iterator pointing to the past-the-end element in the container.

A const_iterator is an iterator that points to const content. This iterator can be increased and decreased (unless it is itself also const), just like the iterator returned by multimap::end, but it cannot be used to modify the contents it points to, even if the multimap object is not itself const.

If the container is empty, this function returns the same as multimap::cbegin.

The value returned shall not be dereferenced.

Parameters

none

Return Value

A const_iterator to the element past the end of the sequence.

Member type const_iterator is a bidirectional iterator type that points to const elements.

// multimap::cbegin/cend
#include <iostream>
#include <map>

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

  // print content:
  std::cout << "mymultimap contains:";
  for (auto it = mymultimap.cbegin(); it != mymultimap.cend(); ++it)
    std::cout << " [" << it->first << ':' << it->second << ']';
  std::cout << '\n';

  return 0;
}


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

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.
