<P>
<p>The <a href="QBuffer.html#QBuffer(com.trolltech.qt.core.QObject)"><tt>QBuffer</tt></a> class provides a <a href="QIODevice.html#QIODevice(com.trolltech.qt.core.QObject)"><tt>QIODevice</tt></a> interface for a <a href="QByteArray.html"><tt>QByteArray</tt></a>.</p>
<p><a href="QBuffer.html#QBuffer(com.trolltech.qt.core.QObject)"><tt>QBuffer</tt></a> allows you to access a <a href="QByteArray.html"><tt>QByteArray</tt></a> using the <a href="QIODevice.html#QIODevice(com.trolltech.qt.core.QObject)"><tt>QIODevice</tt></a> interface. The <a href="QByteArray.html"><tt>QByteArray</tt></a> is treated just as a standard random-accessed file. Example:</p>
<pre>        QBuffer buffer;
        char ch;

        buffer.open(QBuffer::ReadWrite);
        buffer.write(&quot;Qt rocks!&quot;);
        buffer.seek(0);
        buffer.getChar(&amp;ch);  <span class="comment">// ch == 'Q'</span>
        buffer.getChar(&amp;ch);  <span class="comment">// ch == 't'</span>
        buffer.getChar(&amp;ch);  <span class="comment">// ch == ' '</span>
        buffer.getChar(&amp;ch);  <span class="comment">// ch == 'r'</span></pre>
<p>By default, an internal <a href="QByteArray.html"><tt>QByteArray</tt></a> buffer is created for you when you create a <a href="QBuffer.html#QBuffer(com.trolltech.qt.core.QObject)"><tt>QBuffer</tt></a>. You can access this buffer directly by calling <a href="QBuffer.html#buffer()"><tt>buffer</tt></a>. You can also use <a href="QBuffer.html#QBuffer(com.trolltech.qt.core.QObject)"><tt>QBuffer</tt></a> with an existing <a href="QByteArray.html"><tt>QByteArray</tt></a> by calling setBuffer(), or by passing your array to <a href="QBuffer.html#QBuffer(com.trolltech.qt.core.QObject)"><tt>QBuffer</tt></a>'s constructor.</p>
<p>Call <a href="QBuffer.html#open(com.trolltech.qt.core.QIODevice.OpenMode)"><tt>open</tt></a> to open the buffer. Then call <a href="QIODevice.html#write(com.trolltech.qt.core.QByteArray)"><tt>write</tt></a> or putChar() to write to the buffer, and <a href="QIODevice.html#read(long)"><tt>read</tt></a>, <a href="QIODevice.html#readLine(long)"><tt>readLine</tt></a>, <a href="QIODevice.html#readAll()"><tt>readAll</tt></a>, or getChar() to read from it. <a href="QBuffer.html#size()"><tt>size</tt></a> returns the current size of the buffer, and you can seek to arbitrary positions in the buffer by calling <a href="QBuffer.html#seek(long)"><tt>seek</tt></a>. When you are done with accessing the buffer, call <a href="QBuffer.html#close()"><tt>close</tt></a>.</p>
<p>The following code snippet shows how to write data to a <a href="QByteArray.html"><tt>QByteArray</tt></a> using <a href="QDataStream.html"><tt>QDataStream</tt></a> and <a href="QBuffer.html#QBuffer(com.trolltech.qt.core.QObject)"><tt>QBuffer</tt></a>:</p>
<pre>        QByteArray byteArray;
        QBuffer buffer(&amp;byteArray);
        buffer.open(QIODevice::WriteOnly);

        QDataStream out(&amp;buffer);
        out &lt;&lt; QApplication::palette();</pre>
<p>Effectively, we convert the application's <a href="%2E%2E/gui/QPalette.html"><tt>QPalette</tt></a> into a byte array. Here's how to read the data from the <a href="QByteArray.html"><tt>QByteArray</tt></a>:</p>
<pre>        QPalette palette;
        QBuffer buffer(&amp;byteArray);
        buffer.open(QIODevice::ReadOnly);

        QDataStream in(&amp;buffer);
        in &gt;&gt; palette;</pre>
<p><a href="QTextStream.html"><tt>QTextStream</tt></a> and <a href="QDataStream.html"><tt>QDataStream</tt></a> also provide convenience constructors that take a <a href="QByteArray.html"><tt>QByteArray</tt></a> and that create a <a href="QBuffer.html#QBuffer(com.trolltech.qt.core.QObject)"><tt>QBuffer</tt></a> behind the scenes.</p>
<p><a href="QBuffer.html#QBuffer(com.trolltech.qt.core.QObject)"><tt>QBuffer</tt></a> emits <a href="QBuffer.html#readyRead()"><tt>readyRead</tt></a> when new data has arrived in the buffer. By connecting to this signal, you can use <a href="QBuffer.html#QBuffer(com.trolltech.qt.core.QObject)"><tt>QBuffer</tt></a> to store temporary data before processing it. For example, you can pass the buffer to <a href="%2E%2E/network/QFtp.html"><tt>QFtp</tt></a> when downloading a file from an FTP server. Whenever a new payload of data has been downloaded, <a href="QBuffer.html#readyRead()"><tt>readyRead</tt></a> is emitted, and you can process the data that just arrived. <a href="QBuffer.html#QBuffer(com.trolltech.qt.core.QObject)"><tt>QBuffer</tt></a> also emits <a href="QBuffer.html#bytesWritten(long)"><tt>bytesWritten</tt></a> every time new data has been written to the buffer.</p>
