Hi all,


I also have another question that I do not get at the moment. We have the object named IstreamConstructorTablePtr_ in the ddtScheme class. See code snippet below.

template<class Type>
 tmp<ddtScheme<Type>> ddtScheme<Type>::New
 (
     const fvMesh& mesh,
     Istream& schemeData
 )
 {
     if (fv::debug)
     {
         InfoInFunction << "Constructing ddtScheme<Type>" << endl;
     }
 
     if (schemeData.eof())
     {
         FatalIOErrorInFunction
         (
             schemeData
         )   << "Ddt scheme not specified" << endl << endl
             << "Valid ddt schemes are :" << endl
             << IstreamConstructorTablePtr_->sortedToc()
             << exit(FatalIOError);
     }
 
     const word schemeName(schemeData);
 
     typename IstreamConstructorTable::iterator cstrIter =
         IstreamConstructorTablePtr_->find(schemeName);
 
     if (cstrIter == IstreamConstructorTablePtr_->end())
     {
         FatalIOErrorInFunction
         (
             schemeData
         )   << "Unknown ddt scheme " << schemeName << nl << nl
             << "Valid ddt schemes are :" << endl
             << IstreamConstructorTablePtr_->sortedToc()
             << exit(FatalIOError);
     }
 
     return cstrIter()(mesh, schemeData);
}

However, I cannot determine where the object is created or initiated.

Hi.
Declaration and definition of IstreamConstructorTablePtr_ are done in ddtScheme class with two macros: declareRunTimeSelectionTable and defineRunTimeSelectionTable

I presented some thoughts on the subject in the thread Runtime Type Selection. Check it out.
