<a name="details" id="details"></a><h2 class="groupheader">Detailed Description</h2>
<div class="textblock"><p>C++ API: "Smart pointers" for use with and in ICU4C C++ code. </p>
<p>These classes are inspired by</p>
<ul>
<li>std::auto_ptr</li>
<li>boost::scoped_ptr & boost::scoped_array</li>
<li>Taligent Safe Pointers (TOnlyPointerTo)</li>
</ul>
<p>but none of those provide for all of the goals for ICU smart pointers:</p>
<ul>
<li>Smart pointer owns the object and releases it when it goes out of scope.</li>
<li>No transfer of ownership via copy/assignment to reduce misuse. Simpler & more robust.</li>
<li>ICU-compatible: No exceptions.</li>
<li>Need to be able to orphan/release the pointer and its ownership.</li>
<li>Need variants for normal C++ object pointers, C++ arrays, and ICU C service objects.</li>
</ul>
<p>For details see <a href="http://site.icu-project.org/design/cpp/scoped_ptr">http://site.icu-project.org/design/cpp/scoped_ptr</a> </p>
