Exposing a new function in QLAddinCpp

[Lapin]

All,

I have finally manage to compile a new C++ example with QLAddinCpp. I will post the update as soon as I can.
In the meantime, I want to expose new functions (that are already available in XL but not in C++) to play around.

For example, I want to expose ohObjectClassName.
To do so, I have changed the xml file (objects.xml in ohgensrc/functions) as below:

    <Procedure name='ohObjectClassName'>   
      <description>get the object class name</description>
      <alias>ObjectHandler::Repository::instance().className</alias>
      <SupportedPlatforms>
        <SupportedPlatform name='Excel'/>
        <SupportedPlatform name='Cpp'/>
      </SupportedPlatforms>
      <ParameterList>
        <Parameters>
          <Parameter name='ObjectID'>
            <type>string</type>
            <tensorRank>vector</tensorRank>
            <description>Object ID name.</description>
          </Parameter>
        </Parameters>
      </ParameterList>
      <ReturnValue>
        <type>string</type>
        <tensorRank>vector</tensorRank>
      </ReturnValue>
    </Procedure>

The challenge is as below. In AddinCpp, the file valueobjects.hpp is not picking up the changes. While it occurs very easily with the XL addins, the Cpp addins seems to be somewhat broken. My guess is gensrc does not rebuild the valueobjects.hpp/cpp files but I have no clue where to fix it.

If someone have faced the same issue, I would be very gratefull.

I have narrowed down the issue.

In fact everything seems to work fine when you want to expose a QL function through qlgensrc.
It is a different topic when you want to expose a function from the objecthandler through ohgensrc.

My guess is because the files in rules, addins, stubs... for the C++ have not been updated.
I have tried to have a look to see what is missing but if someone could give a direction, that would be great.

I beleive the autogeneration of the OH functions should be working.  
For example, if you look in file...

     ObjectHandler/gensrc/metadata/functions/logging.xml

...under function ohLogSetFile you find <SupportedPlatform
name='Cpp'/>.  And if you look in file...

     QuantLibAddin/Clients/Cpp/qlademo.cpp

...you see that function ohLogSetFile() is called successfully.

So it should just be a question of copying what's there.  After editing
the XML file you need to rebuild.  If using Visual C++ under Windows
then you would rebuild the ohgensrc project.  If using automake under
linux you would invoke make in directory ObjectHandler/gensrc.

Regards,
Eric
