[Paraview] custom reader question regarding python access

[Insley, Joseph A.]

Josh,

I had a similar issue a while back, where I had a custom reader with multiple outputs.  In order to get access to output port 1 I ended up doing something along the lines of:

fooFilter = servermanager.OutputPort(my_reader, 1)
SetActiveSource(fooFilter)
fooFilter.UpdatePipeline()  # may not be required

# to see the names of the point data arrays on this output port
dataInfo = fooFilter.GetDataInformation()
pointDataInfo = dataInfo.getPointDataInformation()
numArrays = pointDataInfo.GetNumberOfArrays()
for foo in range(numArrays):
    aName = pointDataInfo.GetArrayInformation(foo)
    print "name (", foo, "): ", aName


(thanks to Utkarsh, who pointed me in the right direction when I was originally trying to do this)

Hope this helps,
joe

Hi all,

I am adding features to my custom reader, and I need some help.

My reader does the following:
1) Reads the main time-dependent model data
2) Reads 0 or more non model-time dependent files that provide time series information specific points at high temporal resolution.

Currently, I am reading the main model data as a structured grid on Port 0 and the time series files into a multi-block table on port 1.

This works great, as far as it goes, but I cannot figure out how to access any of the port 1 information from within Python.  Everytime I try to fetch data for the source, I get a vtkStructuredGrid structure, with no sign of the multi-block tables.

Can someone give me some advice on how to go about accessing the port1 data from within python?

Thanks,
Josh
