+<hr><a name="_details"></a><h2>Detailed Description</h2>
+<h3>template&lt;class T&gt;<br>
+ class NLMISC::CRefPtr&lt; T &gt;</h3>
+
+<a class="el" href="a03321.html">CRefPtr</a>: an handle on a ptr. T Must derive from <a class="el" href="a02209.html">CRefCount</a>. If you use <a class="el" href="a03321.html">CRefPtr</a>, you can kill the object simply by calling delete (T*)RefPtr, or the <a class="el" href="a03321.html#NLMISC_1_1CRefPtra3">kill()</a> method. All other <a class="el" href="a03321.html">CRefPtr</a> which point to it can know if it has been deleted. (but you must be sure that this ptr is not handle by a SmartPtr, of course...)<p>
+SmartPtr are compatible with RefPtr. A ptr may be link to a <a class="el" href="a03321.html">CRefPtr</a> and a <a class="el" href="a03408.html">CSmartPtr</a>. As example, when the <a class="el" href="a03408.html">CSmartPtr</a> will destroy him, <a class="el" href="a03321.html">CRefPtr</a> will be informed... Sample: <pre class="fragment"><div> <span class="keywordtype">void</span> foo()
+ {
+ A *p;
+ CSmartPtr&lt;A&gt; sp;
+ CRefPtr&lt;A&gt; rp;
+
+ p= <span class="keyword">new</span> A;
+ sp= p; <span class="comment">// OK. p is now owned by sp and will be deleted by sp.</span>
+ rp= p; <span class="comment">// OK. rp handle p.</span>
+ sp= NULL; <span class="comment">// Destruction. p deleted. rp automatically informed.</span>
+ <span class="keywordflow">if</span>(rp==NULL)
+ thisIsGood(); <span class="comment">// rp==NULL.</span>
+ }
+</div></pre><p>
+<b>PERFORMANCE</b> <b>WARNING!</b> <a class="el" href="a03321.html#NLMISC_1_1CRefPtra8">operator=()</a> are about 10 times slower than normal pointers. So use them wisely. For local use, prefer cast the refptr to a normal Ptr. Also, an object used with a <a class="el" href="a03321.html">CRefPtr</a> will allocate a small PtrInfo (one only per object, not per ptr). <dl compact><dt><b>See also:</b></dt><dd><a class="el" href="a03408.html">CSmartPtr</a> </dd></dl>
