<hr><a name="details"></a><h2>Detailed Description</h2>
<b>This class is obsolete.</b> It is provided to keep old source working. We strongly advise against using it in new code.
<p> The TQIODeviceSource class is a TQDataSource that draws data from a <a href="tqiodevice.html">TQIODevice</a>.
<p> This class encapsulates retrieving data from a TQIODevice (such as a <a href="tqfile.html">TQFile</a>).
<hr><h2>Member Function Documentation</h2>
<h3 class=fn><a name="TQIODeviceSource"></a>TQIODeviceSource::TQIODeviceSource ( <a href="tqiodevice.html">TQIODevice</a> * device, int buffer_size = 4096 )
</h3>
Constructs a TQIODeviceSource from the <a href="tqiodevice.html">TQIODevice</a> <em>device</em>. The TQIODevice
<em>must</em> be dynamically allocated, becomes owned by the TQIODeviceSource,
and will be deleted when the TQIODeviceSource is destroyed. <em>buffer_size</em>
determines the size of buffering to use between asynchronous operations.
The higher the <em>buffer_size</em>, the more efficient, but the less interleaved
the operation will be with other processing.
<h3 class=fn><a name="~TQIODeviceSource"></a>TQIODeviceSource::~TQIODeviceSource ()
</h3>
Destroys the TQIODeviceSource, deleting the <a href="tqiodevice.html">TQIODevice</a> from which it was
constructed.
<h3 class=fn>void <a name="enableRewind"></a>TQIODeviceSource::enableRewind ( bool on )<tt> [virtual]</tt>
</h3>
If <em>on</em> is set to TRUE then rewinding is enabled.
No special action is taken. If <em>on</em> is set to
FALSE then rewinding is disabled.
<p>Reimplemented from <a href="tqdatasource.html#enableRewind">TQDataSource</a>.
<h3 class=fn>int <a name="readyToSend"></a>TQIODeviceSource::readyToSend ()<tt> [virtual]</tt>
</h3>
Ready until end-of-file.
<p>Reimplemented from <a href="tqdatasource.html#readyToSend">TQDataSource</a>.
<h3 class=fn>void <a name="rewind"></a>TQIODeviceSource::rewind ()<tt> [virtual]</tt>
</h3>
Calls reset() on the <a href="tqiodevice.html">TQIODevice</a>.
<p>Reimplemented from <a href="tqdatasource.html#rewind">TQDataSource</a>.
<h3 class=fn>bool <a name="rewindable"></a>TQIODeviceSource::rewindable () const<tt> [virtual]</tt>
</h3>
All TQIODeviceSource's are rewindable.
<p>Reimplemented from <a href="tqdatasource.html#rewindable">TQDataSource</a>.
<h3 class=fn>void <a name="sendTo"></a>TQIODeviceSource::sendTo ( <a href="tqdatasink.html">TQDataSink</a> * sink, int n )<tt> [virtual]</tt>
</h3>
Reads a block of data and sends up to <em>n</em> bytes to the <em>sink</em>.
<p>Reimplemented from <a href="tqdatasource.html#sendTo">TQDataSource</a>.
