<div class="descr">
<h2 id="details">Detailed Description</h2>
<p>The <a href="qndefmessage.html">QNdefMessage</a> class provides an NFC NDEF message.</p>
<p>A <a href="qndefmessage.html">QNdefMessage</a> is a collection of 0 or more QNdefRecords. <a href="qndefmessage.html">QNdefMessage</a> inherits from QList&lt;<a href="qndefrecord.html">QNdefRecord</a>&gt; and therefore the standard QList functions can be used to manipulate the NDEF records in the message.</p>
<p>NDEF messages can be parsed from a byte array conforming to the NFC Data Exchange Format technical specification by using the <a href="qndefmessage.html#fromByteArray">fromByteArray</a>() static function. Conversely QNdefMessages can be converted into a byte array with the <a href="qndefmessage.html#toByteArray">toByteArray</a>() function.</p>

<p>Returns an NDEF message parsed from the contents of <i>message</i>.</p>
<p>The <i>message</i> parameter is interpreted as the raw message format defined in the NFC Data Exchange Format technical specification.</p>
<p>If a parse error occurs an empty NDEF message is returned.</p>
