| 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> |
