[Quantlib-dev] question about vector of handl

[Yang, R. <Yan...@sc...>]

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: 

          <Parameter name='YieldCurve' exampleValue='EURYC'
default='""'>

            <type>QuantLib::YieldTermStructure</type>

            <superType>libToHandle</superType>

            <tensorRank>scalar</tensorRank>

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

          </Parameter>

 

Accordingly, I define my xml as:

          <Parameter name='YieldCurve' exampleValue='EURYC'
default='""'>

            <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!
