[Getfem-users] virtual_fem C++ question

[Roman Putanowicz]

Dear All, 

In class virtual_fem I have found the following method:

class virtual_fem : virtual public dal::static_stored_object {
   /* ... */
   public:
     virtual bgeot::pstored_point_tab node_tab(size_type) const;
};

Excuse my ignorance but what C++ mechanism does require this method
to be declared this way?
Is it just a programming convention to differentiate  the call to this
method from the call to the constructor of node_tab object ?

Regards,

Roman
