Detailed Description

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

"Bidirectional and random access iterators have corresponding reverse iterator adaptors that iterate through the data structure in the opposite direction. They have the same signatures as the corresponding iterators. The fundamental relation between a reverse iterator and its corresponding iterator i is established by the identity: 
       &*(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.

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 114 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 120 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 125 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.
