> Hi there,
> For the purpose of the discussion below I'm using Microsoft Visual C++
> with the QuantLibXL__full_vc9 solution containing the QuantLibXLStatic
> project. The overview of exposing a method is:-
>
> 1 - In qlgensrc, add a <Member> element to the objects .xml file.
> 2 - Rebuild qlgensrc project which auto generates/updates the necessary
> files in QuantLibObjects and QuantLibXLStatic projects.
> 3 - Build the QuantLibObjects and QuantLibXLStatic (or rebuild the
> solution).
>
> As an example, lets say we wanted to expose the
> QuantLib::CapFloor::capRates() method (its already exposed so take a
> look at the files mentioned).
>
> 1 - Add to \QuantLibAddin\gensrc\metadata\functions\capfloor.xml the
> element
> <Member name='qlCapFloorCapRates' type='QuantLib::CapFloor'>
> <description>Returns the cap rates for the given CapFloor
> object.</description>
> <libraryFunction>capRates</libraryFunction>
> <SupportedPlatforms>
> <SupportedPlatform name='Excel'/>
> </SupportedPlatforms>
> <ParameterList>
> <Parameters/>
> </ParameterList>
> <ReturnValue>
> <type>QuantLib::Rate</type>
> <tensorRank>vector</tensorRank>
> </ReturnValue>
> </Member>
>
> 2 - Rebuild the qlgensrc project which updates
> \QuantLibXL\qlxl/register/register_capfloor.cpp
> \QuantLibXL\qlxl/functions/capfloor.cpp
> \QuantLibXL\qlxl/functions/functioncount.hpp
> \QuantLibAddin\Docs\auto.pages/volatility.docs
> \QuantLibAddin\Docs\auto.pages/capfloor.doc
>
> 3 - Build QuantLibXLStatic
> In this example no files were change in QuantLibObjects so there was no
> need to build that project. If you are unsure then build the solution
> and it will determine what projects need building.
>
> Some things to keep in mind.
> If your exposing activity results in qlgensrc creating files, make sure
> you include those created files in their projects otherwise you will get
> a link error.
>
> If the method you are exposing requires any processing of what is
> returned by the underlying QuantLib method call then add this processing
> to \QuantLibAddin\qlo\xxx.cpp,hpp. For an example see qlBondDescription
> in \QuantLibAddin\gensrc\metadata\functions\bond.xml and associated
> description() method in \QuantLibAddin\qlo\bond.cpp,hpp
>
> If you get compilation errors in QuantLibObjects/QuantLibXLStatic or
> link errors in QuantLibXLStatic which you can't explain then I've found
> the cause usually to be missing <include></include> file(s) in
> \QuantLibAddin\gensrc\metadata\functions\xxx.xml.
