Base iterator class.

#include <iterator>

template <class Category, class T,  class Distance RWSTD_SIMPLE_DEFAULT(ptrdiff_t)>
struct iterator
{
   typedef T value_type;
   typedef Distance distance_type;
   typedef Category iterator_category;
};

The iterator structure provides a base class from which all other iterator types can be derived. This structure defines an interface that consists of three public types: value_type, distance_type, and iterator_category. These types are used primarily by classes derived from iterator and by the iterator_traits class.

See the iterators section in the Class Reference for a description of iterators and the capabilities associated with various types.
