<div class="descr">
<h2 id="details">Detailed Description</h2>
<p>The <a href="qlinkedlist-iterator.html">QLinkedList::iterator</a> class provides an STL-style non-const iterator for <a href="qlinkedlist.html">QLinkedList</a>.</p>
<p><a href="qlinkedlist.html">QLinkedList</a> features both <a href="containers.html#stl-style-iterators">STL-style iterators</a> and <a href="containers.html#java-style-iterators">Java-style iterators</a>. 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.</p>
<p><a href="qlinkedlist.html">QLinkedList</a><T>::iterator allows you to iterate over a <a href="qlinkedlist.html">QLinkedList</a><T> and to modify the list item associated with the iterator. If you want to iterate over a const <a href="qlinkedlist.html">QLinkedList</a>, use <a href="qlinkedlist-const-iterator.html">QLinkedList::const_iterator</a> instead. It is generally good practice to use <a href="qlinkedlist-const-iterator.html">QLinkedList::const_iterator</a> on a non-const <a href="qlinkedlist.html">QLinkedList</a> as well, unless you need to change the <a href="qlinkedlist.html">QLinkedList</a> through the iterator. Const iterators are slightly faster, and can improve code readability.</p>
<p>The default <a href="qlinkedlist-iterator.html">QLinkedList::iterator</a> constructor creates an uninitialized iterator. You must initialize it using a function like <a href="qlinkedlist.html#begin">QLinkedList::begin</a>(), <a href="qlinkedlist.html#end">QLinkedList::end</a>(), or <a href="qlinkedlist.html#insert">QLinkedList::insert</a>() before you can start iterating. Here's a typical loop that prints all the items stored in a list:</p>
<pre class="cpp">
<span class="type"><a href="qlinkedlist.html#QLinkedList">QLinkedList</a></span><span class="operator"><</span><span class="type"><a href="qstring.html">QString</a></span><span class="operator">></span> list;
list<span class="operator">.</span>append(<span class="string">"January"</span>);
list<span class="operator">.</span>append(<span class="string">"February"</span>);
<span class="operator">.</span><span class="operator">.</span><span class="operator">.</span>
list<span class="operator">.</span>append(<span class="string">"December"</span>);
<span class="type"><a href="qlinkedlist.html#QLinkedList">QLinkedList</a></span><span class="operator"><</span><span class="type"><a href="qstring.html">QString</a></span><span class="operator">></span><span class="operator">::</span>iterator i;
<span class="keyword">for</span> (i <span class="operator">=</span> list<span class="operator">.</span>begin(); i <span class="operator">!</span><span class="operator">=</span> list<span class="operator">.</span>end(); <span class="operator">+</span><span class="operator">+</span>i)
cout <span class="operator"><</span><span class="operator"><</span> <span class="operator">*</span>i <span class="operator"><</span><span class="operator"><</span> endl;
</pre>
<p>STL-style iterators can be used as arguments to <a href="qtalgorithms.html">generic algorithms</a>. For example, here's how to find an item in the list using the qFind() algorithm:</p>
<pre class="cpp">
<span class="type"><a href="qlinkedlist.html#QLinkedList">QLinkedList</a></span><span class="operator"><</span><span class="type"><a href="qstring.html">QString</a></span><span class="operator">></span> list;
<span class="operator">.</span><span class="operator">.</span><span class="operator">.</span>
<span class="type"><a href="qlinkedlist.html#QLinkedList">QLinkedList</a></span><span class="operator"><</span><span class="type"><a href="qstring.html">QString</a></span><span class="operator">></span><span class="operator">::</span>iterator it <span class="operator">=</span> <a href="qtalgorithms-obsolete.html#qFind">qFind</a>(list<span class="operator">.</span>begin()<span class="operator">,</span>
list<span class="operator">.</span>end()<span class="operator">,</span> <span class="string">"Joel"</span>);
<span class="keyword">if</span> (it <span class="operator">!</span><span class="operator">=</span> list<span class="operator">.</span>end())
cout <span class="operator"><</span><span class="operator"><</span> <span class="string">"Found Joel"</span> <span class="operator"><</span><span class="operator"><</span> endl;
</pre>
<p>Let's see a few examples of things we can do with a <a href="qlinkedlist-iterator.html">QLinkedList::iterator</a> that we cannot do with a <a href="qlinkedlist-const-iterator.html">QLinkedList::const_iterator</a>. Here's an example that increments every value stored in a <a href="qlinkedlist.html">QLinkedList</a><int> by 2:</p>
<pre class="cpp">
<span class="type"><a href="qlinkedlist.html#QLinkedList">QLinkedList</a></span><span class="operator"><</span><span class="type">int</span><span class="operator">></span><span class="operator">::</span>iterator i;
<span class="keyword">for</span> (i <span class="operator">=</span> list<span class="operator">.</span>begin(); i <span class="operator">!</span><span class="operator">=</span> list<span class="operator">.</span>end(); <span class="operator">+</span><span class="operator">+</span>i)
<span class="operator">*</span>i <span class="operator">+</span><span class="operator">=</span> <span class="number">2</span>;
</pre>
<p>Here's an example that removes all the items that start with an underscore character in a <a href="qlinkedlist.html">QLinkedList</a><<a href="qstring.html">QString</a>>:</p>
<pre class="cpp">
<span class="type"><a href="qlinkedlist.html#QLinkedList">QLinkedList</a></span><span class="operator"><</span><span class="type"><a href="qstring.html">QString</a></span><span class="operator">></span> list;
<span class="operator">.</span><span class="operator">.</span><span class="operator">.</span>
<span class="type"><a href="qlinkedlist.html#QLinkedList">QLinkedList</a></span><span class="operator"><</span><span class="type"><a href="qstring.html">QString</a></span><span class="operator">></span><span class="operator">::</span>iterator i <span class="operator">=</span> list<span class="operator">.</span>begin();
<span class="keyword">while</span> (i <span class="operator">!</span><span class="operator">=</span> list<span class="operator">.</span>end()) {
<span class="keyword">if</span> ((<span class="operator">*</span>i)<span class="operator">.</span>startsWith(<span class="char">'_'</span>))
i <span class="operator">=</span> list<span class="operator">.</span>erase(i);
<span class="keyword">else</span>
<span class="operator">+</span><span class="operator">+</span>i;
}
</pre>
<p>The call to <a href="qlinkedlist.html#erase">QLinkedList::erase</a>() 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:</p>
<pre class="cpp">
<span class="type"><a href="qlinkedlist.html#QLinkedList">QLinkedList</a></span><span class="operator"><</span><span class="type"><a href="qstring.html">QString</a></span><span class="operator">></span><span class="operator">::</span>iterator i <span class="operator">=</span> list<span class="operator">.</span>begin();
<span class="keyword">while</span> (i <span class="operator">!</span><span class="operator">=</span> list<span class="operator">.</span>end()) {
<span class="type"><a href="qlinkedlist.html#QLinkedList">QLinkedList</a></span><span class="operator"><</span><span class="type"><a href="qstring.html">QString</a></span><span class="operator">></span><span class="operator">::</span>iterator previous <span class="operator">=</span> i;
<span class="operator">+</span><span class="operator">+</span>i;
<span class="keyword">if</span> ((<span class="operator">*</span>previous)<span class="operator">.</span>startsWith(<span class="char">'_'</span>))
list<span class="operator">.</span>erase(previous);
}
</pre>
<p>It might be tempting to write code like this:</p>
<pre class="cpp">
<span class="comment">// WRONG</span>
<span class="keyword">while</span> (i <span class="operator">!</span><span class="operator">=</span> list<span class="operator">.</span>end()) {
<span class="keyword">if</span> ((<span class="operator">*</span>i)<span class="operator">.</span>startsWith(<span class="char">'_'</span>))
list<span class="operator">.</span>erase(i);
<span class="operator">+</span><span class="operator">+</span>i;
}
</pre>
<p>However, this will potentially crash in <code>++i</code>, because <code>i</code> is a dangling iterator after the call to <a href="qlinkedlist.html#erase">erase</a>().</p>
<p>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.</p>
<p><b>Warning:</b> 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 <a href="containers.html#implicit-sharing-iterator-problem">Implicit sharing iterator problem</a>.</p>
