[vtkusers] Re: correct way to determine vtkStreamTracerReasonForTermination?

[Goodwin Lawlor]

Hi Tom,

This came up on the list last April. Here's the last of the thread:
http://public.kitware.com/pipermail/vtkusers/2004-April/073493.html


The synopsis went something like: the Get****() fuctions are for accessing
properties of a class not the outputs, which the ReasonForTermination array
is. The output is accessed through GetOutput() so its updated correctly.
There's new pipeline coming soon that should take care of the complexity of
having more than just a data object in the ouput.
