Detailed Description

template<typename T>
template<typename T>
class QList< T >::const_iterator< T >

The QList::const_iterator class provides an STL style const iterator for QList and QQueue.

See also: QList::constBegin(), QList::constEnd(), QList::iterator

Member Typedef Documentation

template<typename T >

QList< T >::const_iterator< T >::iterator_category

Equivalent to std::random_access_iterator_tag indicating this iterator is a random access iterator.

Constructor & Destructor Documentation

template<typename T >

QList< T >::const_iterator< T >::const_iterator ( )

Constructs an uninitialized iterator.

Methods like operator*() and operator++() should not be called on an uninitialized iterator. Use operator=() to assign a value to it before using it.

See also: QList::begin(), QList::end()

template<typename T >

QList< T >::const_iterator< T >::const_iterator ( const const_iterator< T > & other )

Copy constructs a new QList::const_iterator from other.

template<typename T >

QList< T >::const_iterator< T >::const_iterator ( const iterator & other )

Copy constructs a new QList::const_iterator from other.

template<typename T >

QList< T >::const_iterator< T >::const_iterator ( const_iterator< T > && other )

Move constructs a new QList::const_iterator from other.

template<typename T >

QList< T >::const_iterator< T >::const_iterator ( iterator && other )

Move constructs a new QList::const_iterator from other.

Method Documentation

template<typename T >

bool QList< T >::const_iterator< T >::operator!= ( const_iterator< T > other ) const

Returns true if other points to a different item than this iterator, otherwise returns false.

See also: operator==()

template<typename T >

const T & QList< T >::const_iterator< T >::operator* ( ) const

Returns a reference to the current item.

See also: operator->()

template<typename T >

const_iterator QList< T >::const_iterator< T >::operator+ ( size_type n ) const

Returns an iterator to the item at n positions forward from this iterator. If n is negative the iterator goes backward.

See also: operator-(), operator+=()

template<typename T >

const_iterator & QList< T >::const_iterator< T >::operator++ ( )

The prefix ++ operator advances the iterator to the next item in the list and returns an iterator to the new current item.

Calling this method on QList::cend() causes undefined behavior.

++iter;

See also: operator--()

template<typename T >

const_iterator QList< T >::const_iterator< T >::operator++ ( int )

The postfix ++ operator advances the iterator to the next item in the list and returns an iterator to the previous current item.

Calling this method on QList::cend() causes undefined behavior.

iter++;

template<typename T >

const_iterator & QList< T >::const_iterator< T >::operator+= ( size_type n )

Advances the iterator by n items. If n is negative the iterator goes backward.

See also: operator-=(), operator+()

template<typename T >

int QList< T >::const_iterator< T >::operator- ( const_iterator< T > other ) const

Returns the number of items between the item pointed to by other and the item pointed to by this iterator.

template<typename T >

const_iterator QList< T >::const_iterator< T >::operator- ( size_type n ) const

Returns an iterator to the item at n positions backward from this iterator. If n is negative the iterator goes forward.

See also: operator+(), operator-=()

template<typename T >

const_iterator & QList< T >::const_iterator< T >::operator-- ( )

The prefix -- operator decrements the iterator to the previous item in the list and returns an iterator to the new current item.

Calling this method on QList::cbegin() causes undefined behavior.

--iter;

See also: operator++()

template<typename T >

const_iterator QList< T >::const_iterator< T >::operator-- ( int )

The postfix -- operator decrements the iterator to the previous item in the list and returns an iterator to the previous current item.

Calling this method on QList::cbegin() causes undefined behavior.

iter--;

template<typename T >

const_iterator & QList< T >::const_iterator< T >::operator-= ( size_type n )

Makes the iterator go back by n items. If n is negative the iterator goes forward.

See also: operator+=(), operator-()

template<typename T >

const T * QList< T >::const_iterator< T >::operator-> ( ) const

Returns a pointer to the current item.

See also: operator*()

template<typename T >

bool QList< T >::const_iterator< T >::operator< ( const const_iterator< T > & other ) const

Returns true if the item pointed to by this iterator is less than the item pointed to by the other iterator.

template<typename T >

bool QList< T >::const_iterator< T >::operator< ( const iterator & other ) const

Returns true if the item pointed to by this iterator is less than the item pointed to by the other iterator.

template<typename T >

bool QList< T >::const_iterator< T >::operator<= ( const const_iterator< T > & other ) const

Returns true if the item pointed to by this iterator is less than or equal to the item pointed to by the other iterator.

template<typename T >

bool QList< T >::const_iterator< T >::operator<= ( const iterator & other ) const

Returns true if the item pointed to by this iterator is less than or equal to the item pointed to by the other iterator.

template<typename T >

const_iterator & QList< T >::const_iterator< T >::operator= ( const const_iterator< T > & other )

Copy assigns from other and returns a reference to this object.

template<typename T >

const_iterator & QList< T >::const_iterator< T >::operator= ( const iterator & other )

Copy assigns from other and returns a reference to this object.

template<typename T >

const_iterator & QList< T >::const_iterator< T >::operator= ( const_iterator< T > && other )

Move assigns from other and returns a reference to this object.

template<typename T >

const_iterator & QList< T >::const_iterator< T >::operator= ( iterator && other )

Move assigns from other and returns a reference to this object.

template<typename T >

bool QList< T >::const_iterator< T >::operator== ( const_iterator< T > other ) const

Returns true if other points to the same item as this iterator, otherwise returns false.

See also: operator!=()

template<typename T >

bool QList< T >::const_iterator< T >::operator> ( const const_iterator< T > & other ) const

Returns true if the item pointed to by this iterator is greater than the item pointed to by the other iterator.

template<typename T >

bool QList< T >::const_iterator< T >::operator> ( const iterator & other ) const

Returns true if the item pointed to by this iterator is greater than the item pointed to by the other iterator.

template<typename T >

bool QList< T >::const_iterator< T >::operator>= ( const const_iterator< T > & other ) const

Returns true if the item pointed to by this iterator is greater than or equal to the item pointed to by the other iterator.

template<typename T >

bool QList< T >::const_iterator< T >::operator>= ( const iterator & other ) const

Returns true if the item pointed to by this iterator is greater than or equal to the item pointed to by the other iterator.

template<typename T >

const T & QList< T >::const_iterator< T >::operator[] ( size_type n ) const

Returns a reference to the item at position *this + n.
