<div class="textblock"><p>This class is used to extract a value from an argument. </p>
<p>It is used because we need a special implementation to deal with <a class="el" href="classstd_1_1string.html" title="STL class.">std::string</a> and making a specialiced function puts it in the T segment, thus generating link errors. Having a specialiced class makes the symbols weak. This is not pretty but I don't know how to make it work any other way. </p>
