<h2>Description</h2>
<div class="description">
<p>An <a href="Poco.AutoReleasePool.html" title="class Poco::AutoReleasePool">AutoReleasePool</a> implements simple garbage collection for  reference-counted objects. It temporarily takes ownwership of reference-counted objects that  nobody else wants to take ownership of and releases them  at a later, appropriate point in time. </p>
<p>Note: The correct way to add an object hold by an <a href="Poco.AutoPtr.html" title="class Poco::AutoPtr">AutoPtr</a>&lt;&gt; to an <a href="Poco.AutoReleasePool.html" title="class Poco::AutoReleasePool">AutoReleasePool</a> is by invoking the <a href="Poco.AutoPtr.html" title="class Poco::AutoPtr">AutoPtr</a>'s duplicate() method. Example: </p>
<pre>AutoReleasePool&lt;C&gt; arp;
AutoPtr&lt;C&gt; ptr = new C;
...
arp.add(ptr.duplicate());
</pre>
