It is documented as a full class just for simplicity of documenting the member methods that exist only in <a href="qlist.html">QList</a><<a href="qbytearray.html">QByteArray</a>>.</p> <p>All of <a href="qlist.html">QList</a>'s functionality also applies to <a href="qbytearraylist.html">QByteArrayList</a>. For example, you can use <a href="qlist.html#isEmpty">isEmpty</a>() to test whether the list is empty, and you can call functions like <a href="qlist.html#append">append</a>(), <a href="qlist.html#prepend">prepend</a>(), <a href="qlist.html#insert">insert</a>(), <a href="qlist.html#replace">replace</a>(), <a href="qlist.html#removeAll">removeAll</a>(), <a href="qlist.html#removeAt">removeAt</a>(), <a href="qlist.html#removeFirst">removeFirst</a>(), <a href="qlist.html#removeLast">removeLast</a>(), and <a href="qlist.html#removeOne">removeOne</a>() to modify a <a href="qbytearraylist.html">QByteArrayList</a>. In addition, <a href="qbytearraylist.html">QByteArrayList</a> provides several <a href="qbytearraylist.html#join">join</a>() methods for concatenating the list into a single <a href="qbytearray.html">QByteArray</a>.</p> <p>The purpose of <a href="qbytearraylist.html">QByteArrayList</a> is quite different from that of <a href="qstringlist.html">QStringList</a>. Whereas <a href="qstringlist.html">QStringList</a> has many methods for manipulation of elements within the list, <a href="qbytearraylist.html">QByteArrayList</a> does not. Normally, <a href="qstringlist.html">QStringList</a> should be used whenever working with a list of printable strings. <a href="qbytearraylist.html">QByteArrayList</a> should be used to handle and efficiently join large blobs of binary data, as when sequentially receiving serialized data through a <a href="qiodevice.html">QIODevice</a>.</p> </div> <p><b>See also </b><a href="qbytearray.html">QByteArray</a> and <a href="qstringlist.html">QStringList</a>.</p> <!-- @@@QByteArrayList --> <div class="func"> <h2>Member Function Documentation</h2> <!-- $$$join[overload1]$$$join --> <h3 class="fn" id="join"><a name="join"></a><span class="type"><a href="qbytearray.html">QByteArray</a></span> QByteArrayList::<span class="name">join</span>() const</h3> <p>Joins all the byte arrays into a single byte array.</p> <!-- @@@join --> <!-- $$$join$$$joinconstQByteArray& --> <h3 class="fn" id="join-1"><a name="join-1"></a><span class="type"><a href="qbytearray.html">QByteArray</a></span> QByteArrayList::<span class="name">join</span>(const <span class="type"><a href="qbytearray.html">QByteArray</a></span> &<i>separator</i>) const</h3> <p>Joins all the byte arrays into a single byte array with each element separated by the given <i>separator</i>.</p> <!-- @@@join --> <!-- $$$join$$$joinchar --> <h3 class="fn" id="join-2"><a name="join-2"></a><span class="type"><a href="qbytearray.html">QByteArray</a></span> QByteArrayList::<span class="name">join</span>(<span class="type">char</span> <i>separator</i>) const</h3> <p>Joins all the byte arrays into a single byte array with each element separated by the given <i>separator</i>.</p> <!-- @@@join --> </div> <div class="relnonmem"> <h2>Related Non-Members</h2> <!-- $$$QByteArrayListIterator --> <h3 class="fn" id="QByteArrayListIterator-typedef"><a name="QByteArrayListIterator-typedef"></a>typedef <span class="name">QByteArrayListIterator</span></h3> <p>The QByteArrayListIterator type definition provides a Java-style const iterator for <a href="qbytearraylist.html">QByteArrayList</a>.</p> <p><a href="qbytearraylist.html">QByteArrayList</a> provides both <a href="containers.html#java-style-iterators">Java-style iterators</a> and <a href="containers.html#stl-style-iterators">STL-style iterators</a>.
