           java.lang.String dims,
           java.lang.String units,
           java.lang.String desc)

Constructor when theres no underlying variable. You better set the values too!

Parameters:

ds - the containing NetcdfDataset.

group - the containing group; if null, use rootGroup

parentStructure - parent Structure, may be null

shortName - variable shortName, must be unique within the Group

dims - list of dimension names, space delimited

StructureDS

public StructureDS(Group g,
           Structure orgVar)

Create a StructureDS thats wraps a Structure

Parameters:

g - parent group

orgVar - original Structure

StructureDS

public StructureDS(NetcdfDataset ds,
           Group group,
           Structure parent,
           java.lang.String shortName,
           Structure orgVar)

Wrap the given Structure, making it into a StructureDS. Delegate data reading to the original variable. Does not share cache, iosp. This is for NcML explicit mode

Parameters:

ds - the containing NetcdfDataset.

group - the containing group; may not be null

parent - parent Structure, may be null

shortName - variable shortName, must be unique within the Group

orgVar - the original Structure to wrap.
