IsFwd	Whether iteration proceeds forward.

Constructor & Destructor Documentation

const_page_iterator() [1/2]

template<typename T , typename Allocator , bool IsFwd>

gaia::cnt::const_page_iterator< T, Allocator, IsFwd >::const_page_iterator ( const page_type *  pPage )

inline

Constructs an end iterator at a page boundary.

Parameters

pPage

Boundary page.

const_page_iterator() [2/2]

template<typename T , typename Allocator , bool IsFwd>

gaia::cnt::const_page_iterator< T, Allocator, IsFwd >::const_page_iterator ( const page_type *  pPage, const page_type *  pPageLast  )

inline

Constructs a read-only iterator over a page range.

Parameters

pPage	First page to inspect.
pPageLast	Page marking the range boundary.

Member Function Documentation

operator!=()

template<typename T , typename Allocator , bool IsFwd>

GAIA_NODISCARD bool gaia::cnt::const_page_iterator< T, Allocator, IsFwd >::operator!= ( const iterator &  other ) const

inline

Checks whether two iterators have different positions.

Parameters

other

Iterator to compare with.

Returns

True if the iterators have different positions.

operator*()

template<typename T , typename Allocator , bool IsFwd>

reference gaia::cnt::const_page_iterator< T, Allocator, IsFwd >::operator* ( ) const

inline

Accesses the current element.

Returns

Read-only reference to the current element.

operator++() [1/2]

template<typename T , typename Allocator , bool IsFwd>

iterator & gaia::cnt::const_page_iterator< T, Allocator, IsFwd >::operator++ ( )

inline

Advances to the next element.

Returns

Reference to this advanced iterator.

operator++() [2/2]

template<typename T , typename Allocator , bool IsFwd>

iterator gaia::cnt::const_page_iterator< T, Allocator, IsFwd >::operator++ ( int  )

inline

Advances to the next element.

Returns

Iterator value before advancement.

operator->()

template<typename T , typename Allocator , bool IsFwd>

pointer gaia::cnt::const_page_iterator< T, Allocator, IsFwd >::operator-> ( ) const

inline

Accesses the current element through a pointer.

Returns

Read-only pointer to the current element.

Parameters

other

Iterator to compare with.

Returns

True if both iterators have the same position.
