- \class QListIterator
- \inmodule QtCore
-
- \brief The QListIterator class provides a Java-style const iterator for QList and QQueue.
-
- QList has both \l{Java-style iterators} and \l{STL-style
- iterators}. The Java-style iterators are more high-level and
- easier to use than the STL-style iterators; on the other hand,
- they are slightly less efficient.
-
- An alternative to using iterators is to use index positions. Most
- QList member functions take an index as their first parameter,
- making it possible to access, modify, and remove items without
- using iterators.
-
- QListIterator\<T\> allows you to iterate over a QList\<T\> (or a
- QQueue\<T\>). If you want to modify the list as you iterate over
- it, use QMutableListIterator\<T\> instead.
-
- The QListIterator constructor takes a QList as argument. After
- construction, the iterator is located at the very beginning of
- the list (before the first item). Here's how to iterate over all
- the elements sequentially:
-
- \snippet doc/src/snippets/code/doc_src_qiterator.qdoc 0
-
- The next() function returns the next item in the list and
- advances the iterator. Unlike STL-style iterators, Java-style
- iterators point \e between items rather than directly \e at
- items. The first call to next() advances the iterator to the
- position between the first and second item, and returns the first
- item; the second call to next() advances the iterator to the
- position between the second and third item, and returns the second
- item; and so on.
-
- \img javaiterators1.png
-
- Here's how to iterate over the elements in reverse order:
-
- \snippet doc/src/snippets/code/doc_src_qiterator.qdoc 1
-
- If you want to find all occurrences of a particular value, use
- findNext() or findPrevious() in a loop.
-
- Multiple iterators can be used on the same list. If the list is
- modified while a QListIterator is active, the QListIterator will
- continue iterating over the original list, ignoring the modified
- copy.
