-/*! \class QLinkedList
- \inmodule QtCore
- \obsolete
- \brief The QLinkedList class is a template class that provides linked lists.
-
- \ingroup tools
- \ingroup shared
-
- \reentrant
-
- \note This class is obsolete, please use std::list instead.
-
- QLinkedList\<T\> is one of Qt's generic \l{container classes}. It
- stores a list of values and provides iterator-based access as
- well as \l{constant time} insertions and removals.
-
- QList\<T\>, QLinkedList\<T\>, and QVector\<T\> provide similar
- functionality. Here's an overview:
-
- \list
- \li For most purposes, QList is the right class to use. Its
- index-based API is more convenient than QLinkedList's
- iterator-based API, and it is usually faster than
- QVector because of the way it stores its items in
- memory (see \l{Algorithmic Complexity} for details).
- It also expands to less code in your executable.
- \li If you need a real linked list, with guarantees of \l{constant
- time} insertions in the middle of the list and iterators to
- items rather than indexes, use QLinkedList.
- \li If you want the items to occupy adjacent memory positions,
- use QVector.
- \endlist
-
- Here's an example of a QLinkedList that stores integers and a
- QLinkedList that stores QTime values:
-
- \snippet code/src_corelib_tools_qlinkedlist.cpp 0
-
- QLinkedList stores a list of items. The default constructor
- creates an empty list. To insert items into the list, you can use
- operator<<():
-
- \snippet code/src_corelib_tools_qlinkedlist.cpp 1
-
- If you want to get the first or last item in a linked list, use
- first() or last(). If you want to remove an item from either end
- of the list, use removeFirst() or removeLast(). If you want to
- remove all occurrences of a given value in the list, use
- removeAll().
-
- A common requirement is to remove the first or last item in the
- list and do something with it. For this, QLinkedList provides
- takeFirst() and takeLast(). Here's a loop that removes the items
- from a list one at a time and calls \c delete on them:
- \snippet code/src_corelib_tools_qlinkedlist.cpp 2
-
- QLinkedList's value type must be an \l {assignable data type}. This
- covers most data types that are commonly used, but the compiler
- won't let you, for example, store a QWidget as a value; instead,
- store a QWidget *. A few functions have additional requirements;
- for example, contains() and removeAll() expect the value type to
- support \c operator==(). These requirements are documented on a
- per-function basis.
-
- If you want to insert, modify, or remove items in the middle of
- the list, you must use an iterator. QLinkedList provides both
- \l{Java-style iterators} (QLinkedListIterator and
- QMutableLinkedListIterator) and \l{STL-style iterators}
- (QLinkedList::const_iterator and QLinkedList::iterator). See the
- documentation for these classes for details.

- \inmodule QtCore
- \obsolete
- \brief The QLinkedList::iterator class provides an STL-style non-const iterator for QLinkedList.
-
- QLinkedList features both \l{STL-style iterators} and
- \l{Java-style iterators}. The STL-style iterators are more
- low-level and more cumbersome to use; on the other hand, they are
- slightly faster and, for developers who already know STL, have
- the advantage of familiarity.
-
- QLinkedList\<T\>::iterator allows you to iterate over a
- QLinkedList\<T\> and to modify the list item associated with the
- iterator. If you want to iterate over a const QLinkedList, use
- QLinkedList::const_iterator instead. It is generally good
- practice to use QLinkedList::const_iterator on a non-const
- QLinkedList as well, unless you need to change the QLinkedList
- through the iterator. Const iterators are slightly faster, and
- can improve code readability.
-
- The default QLinkedList::iterator constructor creates an
- uninitialized iterator. You must initialize it using a
- function like QLinkedList::begin(), QLinkedList::end(), or
- QLinkedList::insert() before you can start iterating. Here's a
- typical loop that prints all the items stored in a list:
-
- \snippet code/src_corelib_tools_qlinkedlist.cpp 7
-
- STL-style iterators can be used as arguments to \l{generic
- algorithms}. For example, here's how to find an item in the list:
-
- \snippet code/src_corelib_tools_qlinkedlist.cpp 8
-
- Let's see a few examples of things we can do with a
- QLinkedList::iterator that we cannot do with a QLinkedList::const_iterator.
- Here's an example that increments every value stored in a
- QLinkedList\<int\> by 2:
-
- \snippet code/src_corelib_tools_qlinkedlist.cpp 9
-
- Here's an example that removes all the items that start with an
- underscore character in a QLinkedList\<QString\>:
-
- \snippet code/src_corelib_tools_qlinkedlist.cpp 10
-
- The call to QLinkedList::erase() removes the item pointed to by
- the iterator from the list, and returns an iterator to the next
- item. Here's another way of removing an item while iterating:
-
- \snippet code/src_corelib_tools_qlinkedlist.cpp 11
-
- It might be tempting to write code like this:
-
- \snippet code/src_corelib_tools_qlinkedlist.cpp 12
-
- However, this will potentially crash in \c{++i}, because \c i is
- a dangling iterator after the call to erase().
-
- Multiple iterators can be used on the same list. If you add items
- to the list, existing iterators will remain valid. If you remove
- items from the list, iterators that point to the removed items
- will become dangling iterators.
-
- \warning Iterators on implicitly shared containers do not work
- exactly like STL-iterators. You should avoid copying a container
- while iterators are active on that container. For more information,
- read \l{Implicit sharing iterator problem}.

-/*! \class QLinkedList::const_iterator
- \inmodule QtCore
- \obsolete
- \brief The QLinkedList::const_iterator class provides an STL-style const iterator for QLinkedList.
-
- QLinkedList features both \l{STL-style iterators} and
- \l{Java-style iterators}. The STL-style iterators are more
- low-level and more cumbersome to use; on the other hand, they are
- slightly faster and, for developers who already know STL, have
- the advantage of familiarity.
-
- QLinkedList\<T\>::const_iterator allows you to iterate over a
- QLinkedList\<T\>. If you want modify the QLinkedList as you iterate
- over it, you must use QLinkedList::iterator instead. It is
- generally good practice to use QLinkedList::const_iterator on a
- non-const QLinkedList as well, unless you need to change the
- QLinkedList through the iterator. Const iterators are slightly
- faster, and can improve code readability.
-
- The default QLinkedList::const_iterator constructor creates an
- uninitialized iterator. You must initialize it using a function
- like QLinkedList::constBegin(), QLinkedList::constEnd(), or
- QLinkedList::insert() before you can start iterating. Here's a
- typical loop that prints all the items stored in a list:
-
- \snippet code/src_corelib_tools_qlinkedlist.cpp 14
-
- STL-style iterators can be used as arguments to \l{generic
- algorithms}. For example, here's how to find an item in the list:
-
- \snippet code/src_corelib_tools_qlinkedlist.cpp 15
-
- Multiple iterators can be used on the same list. If you add items
- to the list, existing iterators will remain valid. If you remove
- items from the list, iterators that point to the removed items
- will become dangling iterators.
-
- \warning Iterators on implicitly shared containers do not work
- exactly like STL-iterators. You should avoid copying a container
- while iterators are active on that container. For more information,
- read \l{Implicit sharing iterator problem}.
