question about vector of handl

Hihi,

I have a problem to define a constructor which takes vector of handles as arguments, like

const std::vector<QuantLib::Handle<QuantLib::YieldTermStructure> >&

I can see const QuantLib::Handle<QuantLib::YieldTermStructure>& in QuantLibObjects

The xml is defined as:

<type>QuantLib::YieldTermStructure</type>

<superType>libToHandle</superType>

<tensorRank>scalar</tensorRank>

<description>forecasting yield term structure.</description>

</Parameter>

Accordingly, I define my xml as:

<type>QuantLib::YieldTermStructure</type>

<superType>libToHandle</superType>

<tensorRank>vector</tensorRank>

<description>forecasting yield term structure.</description>

</Parameter>

But when the create_ xxx.cpp is generated, I get one statement:

std::vector<boost::shared_ptr<QuantLib::YieldTermStructure> > DiscountCurvesLibObj =

ObjectHandler::ohVariantToObjectVector<QuantLib::YieldTermStructure, QuantLibAddin::YieldTermStructure>(

DiscountCurves, "DiscountCurves");

This get the error msg: 'ohVariantToObjectVector' : is not a member of 'ObjectHandler'

My version is ql_0_9_7. In this version, I can’t find 'ohVariantToObjectVector' in 'ObjectHandler'. But in previous version, I can. It seems I didn’t define the xml file correctly. Can anybody tell me how to solve this problem? Thanks a lot for your help!

My best guess would be that you defined the XML file correctly, but that
the resulting autogenerated code requires a conversion function that has
not been implemented.

If you see that conversion function in a previous release it probably
means that I deleted it because it was broken and no longer required for
the core code.

Regards,
Eric
