Detailed Description

template<class T>
class QSet< T >::const_iterator

The QSet::const_iterator class provides an STL style const iterator for QSet.

QSet::constBegin(), QSet::constEnd(), QSet::iterator

Member Typedef Documentation

template<class T >
QSet< T >::const_iterator::iterator_category

Equivalent to std::forward_iterator_tag indicating this iterators is a forward iterator.

Constructor & Destructor Documentation

template<class T >
QSet< 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.

QSet::begin(), QSet::end()
template<class T >
QSet< T >::const_iterator::const_iterator ( const const_iterator &  other)

Constructs a copy of other.

template<class T >
QSet< T >::const_iterator::const_iterator ( const iterator &  other)

Copy constructs a new QSet::const_iterator from other.

template<class T >
QSet< T >::const_iterator::const_iterator ( const_iterator &&  other)

Move constructs a new QSet::const_iterator from other.

template<class T >
QSet< T >::const_iterator::const_iterator ( iterator &&  other)

Move constructs a new QSet::const_iterator from other.

Method Documentation

template<class T >
const T & QSet< T >::const_iterator::operator* ( ) const

Returns a reference to the current item.

See also
operator->()
template<class T >
const_iterator QSet< 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.

This operation can be slow for large values of n.

template<class T >
const_iterator & QSet< T >::const_iterator::operator++ ( )

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

Calling this method on QSet::constEnd() leads to undefined behavior.

template<class T >
const_iterator QSet< T >::const_iterator::operator++ ( int  )

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

template<class T >
const_iterator & QSet< T >::const_iterator::operator+= ( size_type  n)

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

This operation can be slow for large values of n.

See also
operator+()
template<class T >
const T * QSet< T >::const_iterator::operator-> ( ) const

Returns a pointer to the current item.

See also
operator*()
template<class T >
const_iterator & QSet< T >::const_iterator::operator= ( const const_iterator &  other)

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

template<class T >
const_iterator & QSet< T >::const_iterator::operator= ( const iterator &  other)

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

template<class T >
const_iterator & QSet< T >::const_iterator::operator= ( const_iterator &&  other)

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

template<class T >
const_iterator & QSet< T >::const_iterator::operator= ( iterator &&  other)

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

template<class T >
bool QSet< T >::const_iterator::operator== ( const_iterator  other) const

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