/* This is a hack */ /* This is a hack.
* Note that SwigValueWrapper should only be generated for value types which are classes and
* the class does not have a default constructor. It is also used for templated classes
* which havn't been passed to SWIG for parsing in case the class does not have a default
* constructor. Tip (SWIG-1.3.22 as of writing): Get SWIG to parse your templated class and
* use the %template directive (unnamed or not) to help SWIG decide whether or not
* SwigValueWrapper should be used, for example
* %template() std::auto_ptr<int>; // unnamed %template does not generate any proxy classes
