reverse_iterator::pointer
A type that provides a pointer to an element addressed by a reverse_iterator.
typedef typename iterator_traits<RandomIterator>::pointer pointer;
Remarks
The type is a synonym for the iterator trait typename iterator_traits<RandomIterator>::pointer.
Example
// reverse_iterator_pointer.cpp
// compile with: /EHsc
#include <iterator>
#include <algorithm>
#include <vector>
#include <utility>
#include <iostream>
int main( )
{
using namespace std;
typedef vector<pair<int,int> > pVector;
pVector vec;
vec.push_back( pVector::value_type( 1,2 ) );
vec.push_back( pVector::value_type( 3,4 ) );
vec.push_back( pVector::value_type( 5,6 ) );
pVector::iterator pvIter;
cout << "The vector vec of integer pairs is:\n" << "( ";
for ( pvIter = vec.begin ( ) ; pvIter != vec.end ( ); pvIter++)
cout << "( " << pvIter -> first << ", " << pvIter -> second << ") ";
cout << ")" << endl;
pVector::reverse_iterator rpvIter;
cout << "\nThe vector vec reversed is:\n" << "( ";
for ( rpvIter = vec.rbegin( ) ; rpvIter != vec.rend( ); rpvIter++)
cout << "( " << rpvIter -> first << ", " << rpvIter -> second << ") ";
cout << ")" << endl;
pVector::iterator pos = vec.begin ( );
pos++;
cout << "\nThe iterator pos points to:\n"
<< "( " << pos -> first << ", "
<< pos -> second << " )" << endl;
pVector::reverse_iterator rpos (pos);
cout << "\nThe iterator rpos points to:\n"
<< "( " << rpos -> first << ", "
<< rpos -> second << " )" << endl;
}
The vector vec of integer pairs is: ( ( 1, 2) ( 3, 4) ( 5, 6) ) The vector vec reversed is: ( ( 5, 6) ( 3, 4) ( 1, 2) ) The iterator pos points to: ( 3, 4 ) The iterator rpos points to: ( 1, 2 )
