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

- operator=()
template<class T >
| bool QVectorIterator< 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 QVectorIterator< 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 QVectorIterator< T >::hasNext |
( |
| ) |
const |
|
inline |
Returns true if there is at least one item ahead of the iterator, otherwise returns false.

- hasPrevious(), next()
template<class T >
| bool QVectorIterator< T >::hasPrevious |
( |
| ) |
const |
|
inline |
Returns true if there is at least one item behind the iterator, otherwise returns false.
- See also
- hasNext(), previous()
template<class T >
| const T & QVectorIterator< T >::next |
( |
| ) |
|
|
inline |
Returns the next item and advances the iterator by one position. Calling this method on an iterator located at the back of the container leads to undefined behavior.
- See also
- hasNext(), peekNext(), previous()
template<class T >
| QVectorIterator & QVectorIterator< T >::operator= |
( |
const QVector< T > & |
vector | ) |
|
|
inline |
Makes the iterator operate on vector. The iterator is set to be at the front of the vector before the first item.
- See also
- toFront(), toBack()
template<class T >
| const T & QVectorIterator< T >::peekNext |
( |
| ) |
const |
|
inline |
Returns the next item without moving the iterator. Calling this method on an iterator located at the back of the container leads to undefined behavior.
- See also
- hasNext(), next(), peekPrevious()
template<class T >
| const T & QVectorIterator< T >::peekPrevious |
( |
| ) |
const |
|
inline |
Returns the previous item without moving the iterator. Calling this method on an iterator located at the front of the container leads to undefined behavior.
- See also
- hasPrevious(), previous(), peekNext()
template<class T >
| const T & QVectorIterator< T >::previous |
( |
| ) |
|
|
inline |
Returns the previous item and moves the iterator back by one position. Calling this method on an iterator located at the front of the container leads to undefined behavior.
- See also
- hasPrevious(), peekPrevious(), next()
template<class T >
| void QVectorIterator< T >::toBack |
( |
| ) |
|
|
inline |
Moves the iterator to the back of the container (after the last item).
- See also
- toFront(), previous()
template<class T >
| void QVectorIterator< T >::toFront |
( |
| ) |
|
|
inline |
Moves the iterator to the front of the container (before the first item).

- toBack(), next()
