Detailed Description

template<typename T>
class QMutableSetIterator< T >

The QMutableSetIterator class provides a Java style iterator for QSet. For more information refer to Java style iterators.

It is not possible to iterate backwards over a QSet since the order is not meaningful. This iterator class is similar to QSetIterator with the addition of of remove(). You can not modify the values in a QSet using iterators. You need to remove and add the element again.

Constructor & Destructor Documentation

template<typename T >
QMutableSetIterator< T >::QMutableSetIterator ( QSet< T > &  set)
inline

Constructs an iterator for traversing set. The iterator is set to be at the front of the set (before the first item).

See also
operator=()
template<typename T >
QMutableSetIterator< T >::~QMutableSetIterator ( )
inline

Destroys the iterator.

Method Documentation

template<typename T >
bool QMutableSetIterator< T >::findNext ( const T &  value)
inline

Searches for value starting from the current iterator position forward. Returns true if value is found, otherwise returns false. After the call, if value was found, the iterator is positioned just after the matching item, otherwise the iterator is positioned at the back of the container.

template<typename T >
bool QMutableSetIterator< T >::findPrevious ( const T &  value)
inline

Searches for value starting from the current iterator position backward. Returns true if value is found, otherwise returns false. After the call, if value was found, the iterator is positioned just before the matching item, otherwise the iterator is positioned at the front of the container.

template<typename T >
bool QMutableSetIterator< T >::hasNext ( ) const
inline

Returns true if there is at least one item ahead of the iterator. This occurs when the iterator is not at the end of the container.

See also
next()
template<typename T >
bool QMutableSetIterator< T >::hasPrevious ( ) const
inline

Returns true if there is at least one item before the iterator. This occurs when the iterator is not at the beginning of the container.

See also
next()
template<typename T >
const T & QMutableSetIterator< T >::next ( )
inline

Returns the next item and advances the iterator by one position. Calling this function on an iterator located at the back of the container leads to undefined results.

See also
hasNext(), peekNext(), previous()
template<typename T >
QMutableSetIterator & QMutableSetIterator< T >::operator= ( QSet< T > &  set)
inline

Makes the iterator operate on set. The iterator is set to be at the front of the set (before the first item).

See also
toFront(), toBack()
template<typename T >
const T & QMutableSetIterator< T >::peekNext ( ) const
inline

Returns the next item without moving the iterator.

Calling this function on an iterator located at the back of the container leads to undefined behavior.

See also
hasNext(), next()
template<typename T >
const T & QMutableSetIterator< T >::peekPrevious ( ) const
inline

Returns the previous item without moving the iterator.

Calling this function on an iterator located at the front of the container leads to undefined results.

See also
hasPrevious(), previous(), peekNext()
template<typename T >
const T & QMutableSetIterator< T >::previous ( )
inline

Returns the previous item and moves the iterator back by one position.

Calling this function on an iterator located at the front of the container leads to undefined results.

hasPrevious(), peekPrevious(), next()
template<typename T >
void QMutableSetIterator< T >::remove ( )
inline

Removes the last item which was jumped over using one of the traversal functions next() and findNext().

while (iter.hasNext()) {
int val = iter.next();
if (val < -32768 || val > 32767) {
iter.remove();
}
}

value()
template<typename T >
void QMutableSetIterator< T >::toBack ( )
inline

Moves the iterator to the back of the container (after the last item).

See also
toFront()
template<typename T >
void QMutableSetIterator< T >::toFront ( )
inline

Moves the iterator to the front of the container (before the first item).

See also
toBack(), next()
template<typename T >
const T & QMutableSetIterator< T >::value ( ) const
inline

Returns the value of the last item that was jumped over using one of the traversal functions next() and findNext().
