reverse_iterator::operator->


public member function
pointer operator->() const;

Dereference iterator

Returns the element pointed by the iterator in order to access one of its members.

The iterator must point to some object (must not be null pointing) in order to be dereferenciable.

Parameters

none

Return value

A pointer to the element pointed by the iterator.
pointer is a member type defined as an alias of the base iterator's own pointer type.

// reverse_iterator::operator-> example
#include <iostream>
#include <iterator>
#include <map>
#include <string>
using namespace std;

int main () {
  map<int,string> numbers;
  numbers.insert (make_pair(1,"one"));
  numbers.insert (make_pair(2,"two"));
  numbers.insert (make_pair(3,"three"));

  typedef map<int,string>::iterator map_iter;

  reverse_iterator<map_iter> rev_end (numbers.begin());

  reverse_iterator<map_iter> rev_iterator (numbers.end());

  for ( ; rev_iterator != rev_end ; ++rev_iterator)
    cout << rev_iterator->first << " " << rev_iterator->second << "\n";

  return 0;
}


Output:

3 three
2 two
1 one
