Class CdfVirtualVars

java.lang.Object

org.autoplot.cdf.CdfVirtualVars

public class CdfVirtualVars
extends java.lang.Object

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 see ftp://cdaweb.gsfc.nasa.gov/pub/CDAWlib/unix/CDAWlib.tar.gz, routine read_myCDF.pro

Method Detail

execute

public static QDataSet execute(java.util.Map<java.lang.String,java.lang.Object> metadata,
                               java.lang.String function,
                               java.util.List<QDataSet> args,
                               ProgressMonitor mon)
                        throws java.lang.IllegalArgumentException

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, in QDataSet semantics such as FILL_VALUE=-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:

Throws:

java.lang.IllegalArgumentException
