.SH DESCRIPTION
The QMapConstIterator class provides an iterator for QMap.
.PP
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.
.PP
For more informations on QMap iterators see QMapIterator.

See also QMap and QMapIterator.
.SH MEMBER FUNCTION DOCUMENTATION
.SH "QMapConstIterator::QMapConstIterator ()"
Constructs an uninitialized iterator.
.SH "QMapConstIterator::QMapConstIterator ( QMapNode<K, T> * p )"
Constructs an iterator starting at node \fIp.\fR
.SH "QMapConstIterator::QMapConstIterator ( const QMapIterator<K,T> & it )"
Constructs a copy of the iterator.
.SH "QMapConstIterator::QMapConstIterator ( const QMapConstIterator<K,T> & it )"
Constructs a copy of the iterator.
.SH "const T& QMapConstIterator::data () const"
Returns a const reference to the data of the current item.
.SH "const K& QMapConstIterator::key () const"
Returns a const reference to the current key.
.SH "bool QMapConstIterator::operator!= ( const QMapConstIterator<K,T> & it ) const"
Compares both iterators and returns TRUE if they point to different items.
.SH "const T& QMapConstIterator::operator* () const"
Asterix operator. Returns a const reference to the current item. The same as data().
.SH "bool QMapConstIterator::operator== ( const QMapConstIterator<K,T> & it ) const"
Compares both iterators and returns TRUE if they point to the same
item.
