Detailed Description

template<typename _Iterator> class std::reverse_iterator< _Iterator >

       &*(reverse_iterator(i)) == &*(i - 1)
 
 

This mapping is dictated by the fact that while there is always a pointer past the end of an array, there might not be a valid pointer before the beginning of an array.' [24.4.1]/1,2

Reverse iterators can be tricky and surprising at first. Their semantics make sense, however, and the trickiness is a side effect of the requirement that the iterators must be safe.

Member Typedef Documentation

template<typename _Iterator> typedef iterator_traits<_Iterator>::difference_type std::reverse_iterator< _Iterator >::difference_type

Distance between iterators is represented as this type.

Reimplemented from std::iterator< iterator_traits< _Iterator >::iterator_category, iterator_traits< _Iterator >::value_type, iterator_traits< _Iterator >::difference_type, iterator_traits< _Iterator >::pointer, iterator_traits< _Iterator >::reference >.

One of the tag types.

Definition at line 109 of file stl_iterator_base_types.h.

template<typename _Iterator> typedef iterator_traits<_Iterator>::pointer std::reverse_iterator< _Iterator >::pointer

This type represents a pointer-to-value_type.

Reimplemented from std::iterator< iterator_traits< _Iterator >::iterator_category, iterator_traits< _Iterator >::value_type, iterator_traits< _Iterator >::difference_type, iterator_traits< _Iterator >::pointer, iterator_traits< _Iterator >::reference >.

Definition at line 109 of file stl_iterator.h.

template<typename _Iterator> typedef iterator_traits<_Iterator>::reference std::reverse_iterator< _Iterator >::reference

This type represents a reference-to-value_type.

Reimplemented from std::iterator< iterator_traits< _Iterator >::iterator_category, iterator_traits< _Iterator >::value_type, iterator_traits< _Iterator >::difference_type, iterator_traits< _Iterator >::pointer, iterator_traits< _Iterator >::reference >.

Definition at line 108 of file stl_iterator.h.

typedef iterator_traits< _Iterator >::value_type std::iterator< iterator_traits< _Iterator >::iterator_category , iterator_traits< _Iterator >::value_type , iterator_traits< _Iterator >::difference_type , iterator_traits< _Iterator >::pointer , iterator_traits< _Iterator >::reference >::value_type [inherited]

The type 'pointed to' by the iterator.

Definition at line 111 of file stl_iterator_base_types.h.

Constructor & Destructor Documentation

template<typename _Iterator> std::reverse_iterator< _Iterator >::reverse_iterator () [inline]

The default constructor default-initializes member current. If it is a pointer, that means it is zero-initialized.

Definition at line 118 of file stl_iterator.h.

template<typename _Iterator> std::reverse_iterator< _Iterator >::reverse_iterator (iterator_type __x) [inline, explicit]

This iterator will move in the opposite direction that x does.

Definition at line 124 of file stl_iterator.h.

template<typename _Iterator> std::reverse_iterator< _Iterator >::reverse_iterator (const reverse_iterator< _Iterator > & __x) [inline]

The copy constructor is normal.

Definition at line 129 of file stl_iterator.h.

template<typename _Iterator> template<typename _Iter > std::reverse_iterator< _Iterator >::reverse_iterator (const reverse_iterator< _Iter > & __x) [inline]

A reverse_iterator across other types can be copied in the normal fashion.
