I think what you want to do is something like:
lines = domain.getX().getLength()
elements = domain.getX().getLength()
There is also a static utility method in visad.python.JPythonMethods:
public static int getDomainSizes(Data d)
that should return the dimensions. This class is a collection of
methods for the Jython work, but is also usable from "regular java"...

I've been searching the email archives for a couple of days now and
cannot seem to find (or perhaps understand) a solution to the following:
I have a netCDF file that I can open up in a visad Plain and it gives me
the FlatField ((Longitude, Latitude) -> Altitude). I would like to get
the X and Y dimension *values* from my netCDF file.
(Performing a getDoubles() or getSamples() on the domain set results in
an index-order array of lat/lon points, i.e. XxY points, and I'm
interested in creating a rectangle of points that outlines my lat/lon
domain. I've noticed, the ucar.unidata.geoloc.LatLonRect class, but was
hoping to use the "raw" data from my files.)
Can someone get me pointed in the right direction on this?
