Conversion Library</h1>
<p>The Conversion Library improves program safety and clarity by performing
otherwise messy conversions. It includes cast-style function templates designed to complement the C++
Standard's built-in casts.</p>
<p>To reduce coupling, particularly to standard library IOStreams, the Boost
Conversion Library is
supplied by several headers:</p>
<ul>
<li>The <a href="cast.htm">boost/polymorphic_cast.hpp and boost/polymorphic_pointer_cast.hpp</a>
headers provide <b>polymorphic_cast<></b>,
<b>polymorphic_downcast<></b> and <b>polymorphic_pointer_downcast<></b> to perform safe casting between
polymorphic types.<br>
</li>
<li>The boost/implicit_cast.hpp header provides <b>implicit_cast<></b>
to perform implicit casts only (no down-cast, no void*->T*, no U->T if T has only explicit constructors for U).<br>
</li>
<li>The <a href="../../doc/html/boost_lexical_cast.html">boost/lexical_cast</a> header provides <b>lexical_cast<></b>
general literal text conversions, such as an <code>int</code> represented as
a <code>string</code>, or vice-versa.</li>
</ul>
