</div><h4>Requirements:</h4>
<p><tt>E</tt> must be <tt>boost::<span class="RenoLink"><a href="exception.html">exception</a></span></tt>, or a type that derives (indirectly) from <tt>boost::<span class="RenoLink"><a href="exception.html">exception</a></span></tt>.</p>
<h4>Effects:</h4>
<div><ul><li> The first overload stores a copy of <tt>v</tt> into <tt>x</tt>. If <tt>x</tt> already contains data of type <tt><span class="RenoLink"><a href="error_info.html">error_info</a></span>&lt;Tag1,T1&gt;</tt>, that data is overwritten.</li>
<li> The <tt>boost::<span class="RenoLink"><a href="http://www.boost.org/libs/tuple/doc/tuple_users_guide.html">tuple</a></span></tt> overload is equivalent to <tt>x &lt;&lt; v.<span class="RenoLink"><a href="http://www.boost.org/libs/tuple/doc/tuple_users_guide.html#accessing_elements">get</a></span>&lt;0&gt;() &lt;&lt; ... &lt;&lt; v.<span class="RenoLink"><a href="http://www.boost.org/libs/tuple/doc/tuple_users_guide.html#accessing_elements">get</a></span>&lt;N&gt;()</tt>.</li>
</ul></div>
<h4>Returns:</h4>
<p><tt>x</tt>.</p>
<div class="RenoIncludeDIV"><h4>Throws:</h4>
<p><tt>std::bad_alloc</tt>, or any exception emitted by <tt>T1..TN</tt> copy constructor.</p>
