[Dune] question about JacobianInverseTransposed

[Aleksejs Fomins]

Dear Dune,

I would be happy if someone could explain me the initializer of the
MultilinearGeometry:


---------------------------------------------------------------

  typedef FieldMatrix< ctype, coorddimension, mydimension > Base;

   public:
     void setup ( const JacobianTransposed &jt )
     {
       detInv_ = MatrixHelper::template rightInvA< mydimension,
coorddimension >( jt, static_cast< Base & >( *this ) );
     }

---------------------------------------------------------------

Namely, I am not sure what does "static_cast< Base & >( *this )" do, and
thus where the inverse of jt is stored?

Thank you,
Aleksejs
