[Dune] question about c++ programming

[Aleksejs Fomins]

Dear Dune,

In several classes in of the GeometryGrid I find methods defined in a
fashion similar to this one.

  public:
    //! evaluate method for global mapping
    void evaluate ( const DomainVector &x, RangeVector &y ) const
    {
      return asImp().evaluate( x, y );
    }

  protected:
    const Implementation &asImp () const
    {
      return static_cast< const Implementation & >( *this );
    }


Am I right to assume that the method evaluate will never be called for
this version of the class, only for its future overrides?

Cheers,
Aleksejs
