Current practice is to use smart pointers and you don't have to worry about
deleting the objects.

Simply change

vtkClass* class = vtkClass::New();

to

#include <vtkSmartPointer.h>
vtkSmartPointer<vtkClass> class = vtkSmartPointer<vtkClass>::New();

There is a short tutorial here: http://www.vtk.org/Wiki/Smart_Pointers

Thanks,

David
