Hi Dave, That won't inherit it, but because data.pf is guaranteed to exist within the definition of a derived field, that should do what you want. -Matt On Tue, May 25, 2010 at 2:26 PM, David Collins wrote:

Would something like what Britton suggested to Charles a while back work?

pf.parameters['temperature_threshold'] = 1.e7 data.pf.parameters['temperature_threshold'].

will pf.h.sphere(whatever)

inherit my new thing?

Hi Dave,

Unfortunately, I don't think there is.  We could potentially set something up, but as it stands I think both the method resolution order of inherited Python objects as well as the name mangling for "private" methods like __set_default_field_parameters (in yt/lagos/BaseDataTypes.py:161) get in the way.

Hi, all--

I've used set_field_parameter for computing quantities, but that works directly on a ExtractedRegions and whatnot.  Is it possible to tie something directly to the hierarchy or pf so that any new objects I create can also see this value?

Thanks, d.

Hi Dave, As it stands, no, but if it's in your data's parameter file, you can add something to your plugins file to have new parameters added when yt parses the parameter file. -Matt On Tue, May 25, 2010 at 3:17 PM, David Collins wrote:

Rad.

Is there an easy way to cram something like into the .yt file.

Thanks! d.
