<div class="descr">
<h2 id="details">Detailed Description</h2>
<p>The <a href="qcborarray-iterator.html">QCborArray::Iterator</a> class provides an STL-style non-const iterator for <a href="qcborarray.html">QCborArray</a>.</p>
<p><a href="qcborarray-iterator.html">QCborArray::Iterator</a> allows you to iterate over a <a href="qcborarray.html">QCborArray</a> and to modify the array item associated with the iterator. If you want to iterate over a const <a href="qcborarray.html">QCborArray</a>, use <a href="qcborarray-constiterator.html">QCborArray::ConstIterator</a> instead. It is generally a good practice to use <a href="qcborarray-constiterator.html">QCborArray::ConstIterator</a> on a non-const <a href="qcborarray.html">QCborArray</a> as well, unless you need to change the <a href="qcborarray.html">QCborArray</a> through the iterator. Const iterators are slightly faster and improve code readability.</p>
<p>Iterators are initialized by using a <a href="qcborarray.html">QCborArray</a> function like <a href="qcborarray.html#begin">QCborArray::begin</a>(), <a href="qcborarray.html#end">QCborArray::end</a>(), or <a href="qcborarray.html#insert">QCborArray::insert</a>(). Iteration is only possible after that.</p>
<p>Most <a href="qcborarray.html">QCborArray</a> functions accept an integer index rather than an iterator. For that reason, iterators are rarely useful in connection with <a href="qcborarray.html">QCborArray</a>. One place where STL-style iterators do make sense is as arguments to <a href="qtalgorithms.html">generic algorithms</a>.</p>
<p>Multiple iterators can be used on the same array. However, be aware that any non-const function call performed on the <a href="qcborarray.html">QCborArray</a> will render all existing iterators undefined.</p>
