expose to excel a function with vector of shared_ptr to objects as argument

[ikku100]

Good day,

The subject says it all: I would like to expose to Excel a function which has as argument a vector of shared_ptr's. The problem is that either I do not know how to write the xml or that the scripts which generate the cpp code from the xml do not know how to handle this combination.

Passing a shared_ptr works, passing a vector of objects works too. But as soon as I pass the combination, it no longer creates the object in the create_XXX.cpp file (so when the constructor is called, it has an unknown argument).

Could someone tell me how to do this?

Ps. below my piece of XML:

    <Constructor name='qlCurvesInterpolator'>
      <libraryFunction>CurvesInterpolator</libraryFunction>
      <SupportedPlatforms>
        <SupportedPlatform name='Excel'/>
        <SupportedPlatform name='Cpp'/>
      </SupportedPlatforms>
      <ParameterList>
        <Parameters>
          <Parameter name='CurveIds'>
            <type>QuantLib::YieldTermStructure</type>
            <tensorRank>vector</tensorRank>
            <description>curve object IDs.</description>
          </Parameter>
        </Parameters>
      </ParameterList>
    </Constructor>

and the error is:
error C2065: 'CurveIdsLibObjPtr' : undeclared identifier

This should do it:

       <Constructor name='qlCurvesInterpolator'>
           <libraryFunction>CurvesInterpolator</libraryFunction>
           <SupportedPlatforms>
               <SupportedPlatform name='Excel'/>
               <SupportedPlatform name='Cpp'/>
           </SupportedPlatforms>
           <ParameterList>
               <Parameters>
                   <Parameter name='CurveIds'>
                       <type>QuantLib::YieldTermStructure</type>
                       <superType>libraryClass</superType>
                       <tensorRank>vector</tensorRank>
                       <description>curve object IDs.</description>
                   </Parameter>
               </Parameters>
           </ParameterList>
       </Constructor>
