[vtk-developers] vtkProcessObject::GetNumberOfRequiredInputs()

[David Gobbi]

Hi Everyone,

I'm wondering what people would think of adding a method
GetNumberOfRequiredInputs() to vtkProcessObject.  It would
make error checking e.g. in drag-and-drop style visual pipeline
building applications easier, since the app would know ahead
of time the minimum number of inputs a particular filter requires.

Any thoughts?
