Hi Aron and all,
Following this discussion....
For what I can see, all the session state is stored in a variable called
"State" inside Internals of vtkSMSessionProxyManager
(vtkSMSessionProxyManagerInternals). This State is of type vtkSMMessage, which
is a typedef of paraview_protobuf::Message.
In other words, the state of the whole session is stored as a generated
protobuf class (or package), which is defined in vtkPVMessage.proto. I guess
this make sense as -- I image -- this makes read/write from a flat XML much
easier (as well as transferring from client-to-server and vice versa). It would
be great if someone with more knowledge on these details can clarify that I am
in fact correct...
Cheers,
Eduardo.

Hi Eduardo,
I think you've basically got it, but the state is more complicated than you
think. Basically everything has a vtkSMProxy, and those proxies contain the
state of the pipeline, representation, and views. Anything that is modified
from the defaults gets saved in the state file. The vtkSMSessionProxyManager is
the root of a session, as you've found.
The input data is saved in the state file as absolute paths, and you do need
the input data. When you read state, it has that intelligent option to search
for the data files in another directory...
I've just been learning this stuff trying to add dynamic lights to ParaView, so
hopefully I'm close :)
HTH, Regards,
Aron

Hello list,
Where is the data structure(s) in the code where all the objects for the state
of a particular ParaView session are kept while it is running?. I have been
reading the code, and I think it should be in the "internals" of
vtkSMSessionProxyManager, but I am unsure. As far as I understand, the state
(which can be saved to XML) is all it takes to recreate a session (Am I right
here? Probably you need the input data as well, right?).
Thanks for the help!,
Eduardo.
P.S.: Are my emails going to SPAM? Can someone respond ("hi") to this email to
confirm otherwise? Thanks !.
