## Detailed Description

template<typename _Category, typename _Tp, typename _Distance = ptrdiff_t, typename _Pointer = _Tp*, typename _Reference = _Tp&>
struct std::iterator< _Category, _Tp, _Distance, _Pointer, _Reference >

Common iterator class.

This class does nothing but define nested typedefs. Iterator classes can inherit from this class to save some work. The typedefs are then used in specializations and overloading.

In particular, there are no default implementations of requirements such as `operator++` and the like. (How could there be?)

## Member Typedef Documentation

## difference_type

template<typename _Category, typename _Tp, typename _Distance = ptrdiff_t, typename _Pointer = _Tp*, typename _Reference = _Tp&>

typedef _Distance std::iterator< _Category, _Tp, _Distance, _Pointer, _Reference >::difference_type

Distance between iterators is represented as this type.

## iterator_category

template<typename _Category, typename _Tp, typename _Distance = ptrdiff_t, typename _Pointer = _Tp*, typename _Reference = _Tp&>

typedef _Category std::iterator< _Category, _Tp, _Distance, _Pointer, _Reference >::iterator_category

One of the tag types.

## pointer

template<typename _Category, typename _Tp, typename _Distance = ptrdiff_t, typename _Pointer = _Tp*, typename _Reference = _Tp&>

typedef _Pointer std::iterator< _Category, _Tp, _Distance, _Pointer, _Reference >::pointer

This type represents a pointer-to-value_type.

## reference

template<typename _Category, typename _Tp, typename _Distance = ptrdiff_t, typename _Pointer = _Tp*, typename _Reference = _Tp&>

typedef _Reference std::iterator< _Category, _Tp, _Distance, _Pointer, _Reference >::reference

This type represents a reference-to-value_type.

Definition at line 138 of file stl_iterator_base_types.h.

## value_type

template<typename _Category, typename _Tp, typename _Distance = ptrdiff_t, typename _Pointer = _Tp*, typename _Reference = _Tp&>

typedef _Tp std::iterator< _Category, _Tp, _Distance, _Pointer, _Reference >::value_type

The type "pointed to" by the iterator.
