Detailed Description

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

The QVector::const_iterator class provides an STL style const iterator for QVector and QStack.

QVector::constBegin(), QVector::constEnd(), QVector::iterator

Member Typedef Documentation

template<typename T >
QVector< T >::const_iterator::iterator_category

A synonym for std::random_access_iterator_tag indicating this iterator is a random access iterator.

Constructor & Destructor Documentation

template<typename T >
QVector< T >::const_iterator::const_iterator ( )

Constructs an uninitialized iterator.

Functions 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
QVector::begin(), QVector::end()
template<typename T >
QVector< T >::const_iterator::const_iterator ( const iterator other)

Copy constructs a new QVector::const_iterator from other.

template<typename T >
QVector< T >::const_iterator::const_iterator ( const_iterator &&  other)

Move constructs a new QList::const_iterator from other.

template<typename T >
QVector< T >::const_iterator::const_iterator ( iterator &&  other)

Move constructs a new QVector::const_iterator from other.

Method Documentation

template<typename T >
bool QVector< T >::const_iterator::operator!= ( const_iterator  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 & QVector< T >::const_iterator::operator* ( ) const

Returns a reference to the current item. You can change the value of an item by using operator*() on the left side of an assignment.

if (*it == "Hello")
*it = "Bonjour";
See also
operator->()
template<typename T >
const_iterator QVector< T >::const_iterator::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 & QVector< T >::const_iterator::operator++ ( )

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

Calling this function on QVector::end() leads to undefined behavior.

See also
operator--()
template<typename T >
const_iterator QVector< T >::const_iterator::operator++ ( int  )

The postfix ++ operator (it++) advances the iterator to the next item in the list and returns an iterator to the previously current item.

template<typename T >
const_iterator & QVector< T >::const_iterator::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 >
size_type QVector< T >::const_iterator::operator- ( const_iterator  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 QVector< T >::const_iterator::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 & QVector< T >::const_iterator::operator-- ( )

The prefix – operator (–it) makes the preceding item current and returns an iterator to the new current item.

Calling this function on QVector::begin() leads to undefined behavior.

See also
operator++()
template<typename T >
const_iterator QVector< T >::const_iterator::operator-- ( int  )

The postfix – operator (it–) makes the preceding item current and returns an iterator to the previously current item.

template<typename T >
const_iterator & QVector< T >::const_iterator::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 * QVector< T >::const_iterator::operator-> ( ) const

Returns a pointer to the current item.

See also
operator*()
template<typename T >
bool QVector< T >::const_iterator::operator< ( const 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 QVector< T >::const_iterator::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 QVector< T >::const_iterator::operator<= ( const 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 >
bool QVector< T >::const_iterator::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 & QVector< T >::const_iterator::operator= ( const iterator other)

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

template<typename T >
const_iterator & QVector< T >::const_iterator::operator= ( const_iterator &&  other)

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

template<typename T >
const_iterator & QVector< T >::const_iterator::operator= ( iterator &&  other)

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

template<typename T >
bool QVector< T >::const_iterator::operator== ( const_iterator  other) const

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

See also
operator!=()
template<typename T >
bool QVector< T >::const_iterator::operator> ( const 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 QVector< T >::const_iterator::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 QVector< T >::const_iterator::operator>= ( const 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 >
bool QVector< T >::const_iterator::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 & QVector< T >::const_iterator::operator[] ( size_type  n) const

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