<h2>Detailed Description</h2>
<p>The QxtWebContent class provides and I/O device for data sent by the web browser</p>
<p>QxtWebContent is a read-only <a href="http://doc.qtsoftware.com/4.5/qiodevice.html">QIODevice</a> subclass that encapsulates data sent from the web browser, for instance in a POST or PUT request.</p>
<p>In order to avoid delays while reading content sent from the client, and to insulate multiple pipelined requests on the same connection from each other, <a href="qxtweb.html">QxtWeb</a> uses QxtWebContent as an abstraction for streaming data.</p>
<p>See also <a href="qxtabstractwebservice.html">QxtAbstractWebService</a>.</p>

<h2>Member Function Documentation</h2>
<h3 class="fn"><a name="QxtWebContent"></a>QxtWebContent::QxtWebContent ( int <i>contentLength</i>, const <a href="http://doc.qtsoftware.com/4.5/qbytearray.html">QByteArray</a> & <i>start</i>, <a href="http://doc.qtsoftware.com/4.5/qiodevice.html">QIODevice</a> * <i>device</i> )</h3>
<p>Constructs a <a href="qxtwebcontent.html">QxtWebContent</a> object.</p>
<p>The content provided by this constructor is the data contained in <i>start</i>, followed by enough data read from the provided <i>device</i> to fill the desired <i>contentLength</i>.</p>
<p>The <a href="qxtwebcontent.html">QxtWebContent</a> object is parented to the <i>device</i>.</p>
<h3 class="fn"><a name="QxtWebContent-2"></a>QxtWebContent::QxtWebContent ( int <i>contentLength</i>, <a href="http://doc.qtsoftware.com/4.5/qiodevice.html">QIODevice</a> * <i>device</i> )</h3>
<p>Constructs a <a href="qxtwebcontent.html">QxtWebContent</a> object.</p>
<p>The content provided by this constructor is the first <i>contentLength</i> bytes read from the provided <i>device</i>.</p>
<p>The <a href="qxtwebcontent.html">QxtWebContent</a> object is parented to the <i>device</i>.</p>
<h3 class="fn"><a name="QxtWebContent-3"></a>QxtWebContent::QxtWebContent ( const <a href="http://doc.qtsoftware.com/4.5/qbytearray.html">QByteArray</a> & <i>content</i>, <a href="http://doc.qtsoftware.com/4.5/qobject.html">QObject</a> * <i>parent</i> = 0 )</h3>
<p>Constructs a <a href="qxtwebcontent.html">QxtWebContent</a> object with the specified <i>parent</i>.</p>
<p>The content provided by this constructor is exactly the data contained in <i>content</i>.</p>
<h3 class="fn"><a name="ignoreRemainingContent"></a>void QxtWebContent::ignoreRemainingContent () <tt> [slot]</tt></h3>
<p>Discards any data not yet read.</p>
<p>After invoking this function, any further data received from the browser is silently discarded.</p>
<h3 class="fn"><a name="parseUrlEncodedQuery"></a><a href="http://doc.qtsoftware.com/4.5/qhash.html">QHash</a><<a href="http://doc.qtsoftware.com/4.5/qstring.html">QString</a>, <a href="http://doc.qtsoftware.com/4.5/qstring.html">QString</a>> QxtWebContent::parseUrlEncodedQuery ( const <a href="http://doc.qtsoftware.com/4.5/qstring.html">QString</a> & <i>data</i> ) <tt> [static]</tt></h3>
<p>Extracts the key/value pairs from application/x-www-form-urlencoded <i>data</i>, such as the query string from the URL or the form data from a POST request.</p>
<h3 class="fn"><a name="unreadBytes"></a><a href="http://doc.qtsoftware.com/4.5/qtglobal.html#qint64-typedef">qint64</a> QxtWebContent::unreadBytes () const</h3>
<p>Returns the number of bytes of content that have not yet been read.</p>
<p>Note that not all of the remaining content may be immediately available for reading. This function returns the content length, minus the number of bytes that have already been read.</p>
<h3 class="fn"><a name="waitForAllContent"></a>void QxtWebContent::waitForAllContent ()</h3>
<p>Blocks until all of the streaming data has been read from the browser.</p>
<p>Note that this function will block events for the thread on which it is called. If the main thread is blocked, <a href="qxtweb.html">QxtWeb</a> will be unable to process additional requests until the content has been received.</p>
