<h2>Detailed Description</h2>
<p>The QMailPassThroughCodec class uses the <a href="qmailcodec.html">QMailCodec</a> interface to move data between streams without coding or decoding.</p>
<p>The QMailPassThroughCodec allows client code to use the same <a href="qmailcodec.html">QMailCodec</a> interface to convert data between different ASCII encodings, or no encoding at all, without having to be aware of the details involved.</p>
<p>The pass-through codec is primarily useful when communicating with SMTP servers supporting the <a href="http://www.ietf.org/rfc/rfc1652.txt">RFC 1652</a> (8BITMIME) extension, which permits the exchange of data without coding via 7-bit ASCII.</p>
<p>A QMailPassThroughCodec can be instantiated directly, but is more likely to be used polymorphically:</p>
<pre><span class="comment"> // Get an object to perform the encoding required for the current server</span>
QMailCodec* encoder = getCodecForServer(currentServer());
<span class="comment"> // If the codec returned is a QMailPassThroughCodec, the input data will</span>
<span class="comment"> // be written to the output stream without encoding to 7-bit ASCII</span>
encoder->encode(outputStream, inputStream);</pre>
<p>See also <a href="qmailcodec.html">QMailCodec</a>.</p>
