[vtk-developers] [vtkStreamTracer] Why does it support repeatable port 0, the one who supplies vector field?

I am a greenhorn here. Today when I read the code of vtkStreamTracer, in
"FillInputPortInformation(int port, vtkInformation *info)" I found the port
0 is repeatable.
Why is it set to be repeatable? If it should be repeatable, i.e. we can
have different vtkDataSet to supply vector fields, how can we pick the
active data set? Using SetInputToProcess?
