<h2>Abstract</h2>
|
||||
<h2>Introduction</h2>
|
||||
<p>The purpose of Boost Exception is to ease the design of exception class hierarchies and to help write exception handling and error reporting code.</p>
|
||||
<p>It supports transporting of arbitrary data to the catch site, which is otherwise tricky due to the no-throw requirements (15.5.1) for exception classes. Data can be added to any exception object, either directly in the throw-expression (15.1), or at a later time as the exception object propagates up the call stack.</p>
|
||||
<p>The ability to add data to exception objects after they have been passed to <tt>throw</tt> is important, because often some of the information needed to handle an exception is unavailable in the context where the failure is detected. </p>
|
||||
<p>Boost Exception also supports <span class="RenoLink"><a href="cloning.html">cloning</a></span> of exception objects, implemented non-intrusively and automatically by the <tt>boost::<span class="RenoLink"><a href="throw_exception.html">throw_exception</a></span>()</tt> function.</p>

<p>Boost Exception was accepted as a Boost library on November 7 2007, however it has not yet been part of an official Boost release. Current version can be downloaded from <span class="RenoLink"><a href="http://svn.boost.org/svn/boost/trunk"> Boost SVN</a></span>.</p>
