|
<p>Level 1 metadata iterator. </p>
|
|
<p>The flow through the iterator in the C++ layer is similar to the C layer:</p><ul>
|
|
<li>Create a <a class="el" href="classFLAC_1_1Metadata_1_1SimpleIterator.html">SimpleIterator</a> instance</li>
|
|
<li>Check <a class="el" href="classFLAC_1_1Metadata_1_1SimpleIterator.html#acd4f5f18a3b5f7c42677e6a234543366" title="Returns true iff object was properly constructed. ">SimpleIterator::is_valid()</a></li>
|
|
<li>Call <a class="el" href="classFLAC_1_1Metadata_1_1SimpleIterator.html#a67dc75f18d282f41696467f1fbf5c3e8" title="See FLAC__metadata_simple_iterator_init(). ">SimpleIterator::init()</a> and check the return</li>
|
|
<li>Traverse and/or edit. Edits are written to file immediately.</li>
|
|
<li>Destroy the <a class="el" href="classFLAC_1_1Metadata_1_1SimpleIterator.html">SimpleIterator</a> instance</li>
|
|
</ul>
|
|
<p>The ownership of pointers in the C++ layer follows that in the C layer, i.e.</p><ul>
|
|
<li>The objects returned by get_block() are yours to modify, but changes are not reflected in the FLAC file until you call set_block(). The objects are also yours to delete; they are not automatically deleted when passed to set_block() or insert_block_after().</li>
|
|
</ul>
|
|
<p>See the <a class="el" href="group__flac__metadata__level1.html">C layer equivalent </a> for more. </p>
