[vtk-developers] abstract/concrete etc

[John Biddiscombe]

I asked some time ago if anyone could explain why certain classes are 
declared as concrete
vtkObject, vtkProcessObject, vtkImageSource etc etc
when they aren't supposed to be.

some, such as vtkImageMapper are overridden in the object factories to 
create the correct type so are allowed to be concrete, but many are not. 
I'd like to change some to abstract in the makefile.in files
a) does anyone object
b) will newer parsing code invalidate it all anyway? (I suspect not, 
because it still won't know that vtkProcessObect is abstract...)

thanks
