[Paraview] pvpython question

[Stephens, Michael M ERDC-ITL-MS]

on page 302 of the paraview 3 user guide there is a footnote 8 that says:

"When running in built-in mode, there is a way of getting access to the
output of an algorithm directly, but it is too advanced to cover here."

if it's too advanced for a book, i'll assume it's too advance for an email
response; but
i'll ask anyway.

anyone know how to do what is mentioned in the footnote?
