Public Types

typedef _Distance difference_type
Distance between iterators is represented as this type. typedef _Category iterator_category
One of the tag types. typedef _Pointer pointer
This type represents a pointer-to-value_type. typedef _Reference reference
This type represents a reference-to-value_type. typedef _Tp value_type
The type 'pointed to' by the iterator.

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?)

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.

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.

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.

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.

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.
