template<class T >
| QListIterator< T >::QListIterator |
( |
const QList< T > & |
list | ) |
|
|
inline |
Constructs an iterator for traversing list. The iterator is set to be at the front of the list (before the first item).

- operator=()
template<class T >
| bool QListIterator< T >::findNext |
( |
const T & |
value | ) |
|
|
inline |
Searches for value starting from the current iterator position and moving forward. Returns true if the specified value is found, otherwise it returns false. If value is found the iterator is positioned just after the matching item, otherwise the iterator is positioned at the end of the container.

- findPrevious()
template<class T >
| bool QListIterator< T >::findPrevious |
( |
const T & |
value | ) |
|
|
inline |
Searches for value starting from the current iterator position and moving backward. Returns true if the specified value is found, otherwise it returns false. If value was found the iterator is positioned just before the matching item. Otherwise the iterator is positioned at the beginning of the container.

- findNext()
template<class T >
| bool QListIterator< T >::hasNext |
( |
| ) |
const |
|
inline |
Returns true if there is at least one item ahead of the iterator, i.e. the iterator is not at the back of the container, otherwise returns false.

- hasPrevious(), next()
template<class T >
| bool QListIterator< T >::hasPrevious |
( |
| ) |
const |
|
inline |
Returns true if there is at least one item behind the iterator, i.e. the iterator is not at the front of the container, otherwise returns false.
- See also
- hasNext(), previous()
template<class T >
| const T & QListIterator< 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 behavior.

- hasNext(), peekNext(), previous()
template<class T >
| QListIterator & QListIterator< T >::operator= |
( |
const QList< T > & |
list | ) |
|
|
inline |
Makes the iterator operate on list. The iterator is set to be at the front of the list (before the first item).

- toFront(), toBack()
template<class T >
| const T & QListIterator< 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.

- hasNext(), next(), peekPrevious()
template<class T >
| const T & QListIterator< 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 behavior.
- See also
- hasPrevious(), previous(), peekNext()
template<class T >
| const T & QListIterator< 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 behavior.

- hasPrevious(), peekPrevious(), next()
template<class T >
| void QListIterator< T >::toBack |
( |
| ) |
|
|
inline |
Moves the iterator to the back of the container (after the last item).
- See also
- toFront(), previous()
template<class T >
| void QListIterator< T >::toFront |
( |
| ) |
|
|
inline |
Moves the iterator to the front of the container (before the first item).
