Constructor Detail

VirtualReal

public VirtualReal(RealType type,
                   ucar.netcdf.Variable var,
                   SimpleSet rangeSet,
                   Unit unit,
                   visad.data.netcdf.in.Vetter vetter)

Constructs from a scalar type, a 1-D netCDF variable, a range set, a unit, and a value vetter.

Parameters:

type - The type of the nested scalar.

var - The 1-D netCDF variable.

rangeSet - The range set of the values.

unit - The unit of the values.

vetter - The value vetter.
