<hr><h2><a name="details"></a>Detailed Description</h2>
The QIODeviceSource class is a <a href="qdatasource.html">QDataSource</a> that draws data from a <a href="qiodevice.html">QIODevice</a>
<p>
This class encapsulates retrieving data from a QIODevice (such as a <a href="qfile.html">QFile</a>).
<hr><h2>Member Function Documentation</h2>
<h3 class="fn"><a name="8e1379"></a>QIODeviceSource::QIODeviceSource(<a href="qiodevice.html">QIODevice</a>*device, intbuffer_size=4096)</h3>
<p>Constructs a QIODeviceSource from a pointer to an <a href="qiodevice.html">QIODevice</a>. The QIODevice
<em>must</em> be dynamically allocated, becomes owned by the QIODeviceSource,
and will be deleted when the QIODeviceSource destructs. <em>buffer_size</em>
determines the size of buffering to use between asynchronous operations.
The higher <em>buffer_size,</em> the more efficient but the less interleaved
the operation will be with other processing.
<h3 class="fn"><a name="337a7e"></a>QIODeviceSource::~QIODeviceSource()</h3>
<p>Destructs the QIODeviceSource, deleting the <a href="qiodevice.html">QIODevice</a> from which it was
constructed.
<h3 class="fn">void<a name="22bde1"></a>QIODeviceSource::enableRewind(boolon) <code>[virtual]</code></h3>
<p>Enables rewinding. No special action is taken.
<p>Reimplemented from <a href="qdatasource.html#70ae9e">QDataSource.</a>
<h3 class="fn">int<a name="2e58fe"></a>QIODeviceSource::readyToSend() <code>[virtual]</code></h3>
<p>Ready until end-of-file.
<p>Reimplemented from <a href="qdatasource.html#1e015e">QDataSource.</a>
<h3 class="fn">void<a name="4e70f1"></a>QIODeviceSource::rewind() <code>[virtual]</code></h3>
<p>Calls reset() on the <a href="qiodevice.html">QIODevice</a>.
<p>Reimplemented from <a href="qdatasource.html#9061dd">QDataSource.</a>
<h3 class="fn">bool<a name="9e4680"></a>QIODeviceSource::rewindable()const <code>[virtual]</code></h3>
<p>All QIODeviceSource's are rewindable.
<p>Reimplemented from <a href="qdatasource.html#121cd0">QDataSource.</a>
<h3 class="fn">void<a name="bb20f1"></a>QIODeviceSource::sendTo(<a href="qdatasink.html">QDataSink</a>*sink, int<a href="n.html">n</a>) <code>[virtual]</code></h3>
<p>Reads and sends a block of data.
