[vtkusers] Non-virtual version of vtkDataArrayTemplate

[Matthieu Heitz]

Hi all !

I have a template class myClass<T>, where T can be a scalar (float, int,
double, etc.)
I would like to create a vtkFloatArray, vtkIntArray, or vtkDoubleArray,
depending on the type T.
I thought that vtkDataArrayTemplate<T> would be a good solution.
Unfortunately, it is a virtual class, so I can't write this :

vtkSmartPointer< vtkDataArrayTemplate<T> > array =
vtkSmartPointer<vtkDataArrayTemplate<T> >::New();

because when I try to instantiate a myClass<float>, I get the error :

error: invalid conversion from ‘vtkObject*’ to
‘vtkDataArrayTemplate<float>*’ [-fpermissive]

So my question is: Is there an non-virtual version of vtkDataArrayTemplate
that would allow me to create a vtkFloatArray when T is float,
vtkDoubleArray when T is double, etc.

P.S: I use VTK 6.0.0

Thank you !
