QValueListConstIterator Class Reference

Detailed Description

In contrast to QValueListIterator, this class is used to iterate over a const list. It does not allow modification of the values of the list since that would break const semantics.

You can create the appropriate const iterator type by using the const_iterator typedef provided by QValueList.

For more information on QValueList iterators, see QValueListIterator.

Member Function Documentation

QValueListConstIterator::QValueListConstIterator ()

Creates un uninitialized iterator.

QValueListConstIterator::QValueListConstIterator ( const QValueListConstIterator<T> & it )

This is an overloaded member function, provided for convenience. It behaves essentially like the above function.

Constructs a copy of the iterator it.

QValueListConstIterator::QValueListConstIterator ( const QValueListIterator<T> & it )

Constructs a copy of the iterator it.

bool QValueListConstIterator::operator!= ( const QValueListConstIterator<T> & it ) const

Compares this iterator with it and returns TRUE if they point to different items; otherwise returns FALSE.

const T & QValueListConstIterator::operator* () const

Asterisk operator. Returns a reference to the current iterator item.

QValueListConstIterator<T> & QValueListConstIterator::operator++ ()

Prefix ++ makes the succeeding item current and returns an iterator pointing to the new current item. The iterator cannot check whether it reached the end of the list. Incrementing the iterator returned by end() causes undefined results.

QValueListConstIterator<T> QValueListConstIterator::operator++ ( int )

This is an overloaded member function, provided for convenience. It behaves essentially like the above function.

Postfix ++ makes the succeeding item current and returns an iterator pointing to the new current item. The iterator cannot check whether it reached the end of the list. Incrementing the iterator returned by end() causes undefined results.

QValueListConstIterator<T> & QValueListConstIterator::operator-- ()

Prefix -- makes the previous item current and returns an iterator pointing to the new current item. The iterator cannot check whether it reached the beginning of the list. Decrementing the iterator returned by begin() causes undefined results.

QValueListConstIterator<T> QValueListConstIterator::operator-- ( int )

This is an overloaded member function, provided for convenience. It behaves essentially like the above function.

Postfix -- makes the previous item current and returns an iterator pointing to the new current item. The iterator cannot check whether it reached the beginning of the list. Decrementing the iterator returned by begin() causes undefined results.

bool QValueListConstIterator::operator== ( const QValueListConstIterator<T> & it ) const

Compares this iterator with it and returns TRUE if they point to the same item; otherwise returns FALSE.
