[Quantlib-dev] Return object in QLXL

[Peter C. <pet...@ar...>]

Hi,

I have a little problem ...

There is a class KernelDensity declared as follows in the type.xml file:

<DataType defaultSuperType='libraryClass'>QuantLib::KernelDensity</DataType>

There is a second class RiskEngine with a member function which returns a shared_ptr<KerndelDensity>. In QuantLib:

boost::shared_ptr<KernelDensity> kernelDensity(string name, int method); 

The xml for the declaration of this member function looks like this:

   <ReturnValue>
        <type>QuantLib::KernelDensity</type>
        <tensorRank>scalar</tensorRank>
   </ReturnValue>

When I compile the whole thing I get

error C2440: 'Initialisierung': 'boost::shared_ptr<T>' kann nicht in 'std::basic_string<_Elem,_Traits,_Ax>' konvertiert werden
with
2>            T=QuantLib::KernelDensity
2>        and
2>            _Elem=char,
2>            _Traits=std::char_traits<char>,
2>            _Ax=std::allocator<char>

I did not find an example in the existing code where an object (other than native types) is returned, so can someone explain to me, how to do this?

Thanks a lot in advance, best regards
Peter
