Luna::ReverseIterator

An iterator adaptor that reverses the direction of a given iterator.

template <typename _Iter>
class Luna::ReverseIterator

The given iterator must be at least an bidirectional iterator.

Member functions

• constexpr ReverseIterator()

  Constructs an empty reverse iterator.

• constexpr ReverseIterator(iterator_type i)

  Constructs a reverse iterator for the given iterator.

• constexpr ReverseIterator(const ReverseIterator &ri)

  Constructs a reverse iterator by coping from the specified reverse iterator.

• constexpr ReverseIterator(const ReverseIterator< _Uty > &ri)

  Constructs a reverse iterator by coping from the specified reverse iterator of different iterator type.

• constexpr iterator_type base() const

  Gets the base iterator of this reverse iterator.

• constexpr reference operator*() const

  Gets the object this iterator points to.

• constexpr pointer operator->() const

  Gets one pointer to the object this iterator points to.

• constexpr ReverseIterator & operator++()

  Pre-increments the iterator to the next object, which is the last object the base iterator points to.

• constexpr ReverseIterator operator++(int)

  Post-increments the iterator to the next object, which is the last object the base iterator points to.

• constexpr ReverseIterator & operator--()

  Pre-decrements the iterator to the last object, which is the next object the base iterator points to.

• constexpr ReverseIterator operator--(int)

  Post-decrements the iterator to the last object, which is the next object the base iterator points to.

• constexpr ReverseIterator operator+(isize n) const

  Gets one iterator which is advanced by n positions respectively.

• constexpr ReverseIterator & operator+=(isize n)

  Advances the iterator by n positions respectively.

• constexpr ReverseIterator operator-(isize n) const

  Gets one iterator which is advanced by -n positions respectively.

• constexpr ReverseIterator & operator-=(isize n)

  Advances the iterator by -n positions respectively.

• constexpr reference operator[](isize n) const

  Returns a reference to the element at specified relative location.
