Detailed Description

In contrast to QMapIterator this class is used to iterate over a const map. It does not allow to modify the values of the map since this would break the const semantics.

For more informations on QMap iterators see QMapIterator.

Member Function Documentation

QMapConstIterator::QMapConstIterator ()

Creates an uninitialized iterator.

QMapConstIterator::QMapConstIterator ( const QMapIterator<K,T> & it )

Constructs a copy of the iterator.

QMapConstIterator::QMapConstIterator ( const QMapConstIterator<K,T> & it )

Constructs a copy of the iterator.

const T& QMapConstIterator::data () const

Returns a const reference to the data of the current item.

const K& QMapConstIterator::key () const

Returns a const reference to the current key.

bool QMapConstIterator::operator!= ( const QMapConstIterator<K,T> & it ) const

Compares both iterators and returns TRUE if they point to different items.

const T& QMapConstIterator::operator* () const

Asterix operator. Returns a const reference to the current item. The same as data().

bool QMapConstIterator::operator== ( const QMapConstIterator<K,T> & it ) const

Compares both iterators and returns TRUE if they point to the same item.
