If mofData is Real, you can get its value by:
double value = ((Real) mofData)).getValue();
In general, if the MathType of a Field is something like:
((x, y) -> z)
then the samples of the Field will be Real. If the MathType
of the Field is something like:
((x, y) -> (z, w))
then the samples of the Field will be Tuple (actually RealTuple
which is a subclass of Tuple).
So it could be that the netCDF adapter is not reading your
file the way you think it should be. I am not sure how it
will deal with Text values.
Perhaps Steve can tell us.
Cheers,
Bill
