org.autoplot.cdf.CdfVirtualVars
Implementations of the CDF virtual variables seen in CDAWeb, but implemented in QDataSet.
These should reflect a subset of those functions, with the IDL implementations at
http://spdf.gsfc.nasa.gov/CDAWlib.html

execute
execute( java.util.Map metadata, String function, java.util.List args, ProgressMonitor mon ) → QDataSet
Implementations of CDF virtual functions. These are a subset of those in the CDAWeb library, plus a couple
extra that they will presumably add to the library at some point.
Parameters
metadata - the metadata for the new result dataset, CDF semantics such as FILLVAL=-1e31
function - the function name, which is case insensitive. See code isSupported for list of function names.
args - list of QDataSets that are the arguments to the function
mon - monitor for the function
Returns:
the computed variable.

isSupported
isSupported( String function ) → boolean
return true if the function is supported.
Parameters
function - the function name, such as "compute_magnitude"
Returns:
true if the function is supported.
