Boost Exception In other libraries, watch for compile error referring to throw_exception_assert_compatibility in boost::throw_exception. Resolve by throwing an exception that derives from std::exception. This is not a new requirement but it is being enforced now. [SVN r46818]

<p>Some exception hierarchies can not be modified to make boost::<span class="RenoLink"><a href="exception.html">exception</a></span> a base type. In this case, the <span class="RenoLink"><a href="enable_error_info.html">enable_error_info</a></span> function template can be used to make exception objects derive from boost::<span class="RenoLink"><a href="exception.html">exception</a></span> anyway. Here is an example:</p>

Boost Exception major refactoring: works with or without RTTI, vastly improved boost::throw_exception integration. [SVN r48905]
2008-09-19 20:29:26 +00:00
<p>The call to <span class="RenoLink"><a href="enable_error_info.html">enable_error_info</a></span>&lt;T&gt; gets us an object of <i>unspecified type</i> which is guaranteed to derive from both boost::<span class="RenoLink"><a href="exception.html">exception</a></span> and T. This makes it possible to use <span class="RenoLink"><a href="exception_operator_shl.html">operator&lt;&lt;</a></span> to store additional information in the exception object. The exception can be intercepted as T &amp;, so existing exception handling will not break. It can also be intercepted as boost::<span class="RenoLink"><a href="exception.html">exception</a></span> &amp;, so that <span class="RenoLink"><a href="tutorial_transporting_data.html">more information can be added to the exception at a later time</a></span>.</p>
