Class TupleQuantity

java.lang.Object

ucar.visad.Quantity

ucar.visad.TupleQuantity

public abstract class TupleQuantity
extends Quantity

Provides support for tuple quantities. This class uses the decorator design pattern to add convenience methods to its superclass and to form the root of a hierarchy of classes that serve to encapsulate knowledge about scientific quantities that either have multiple components or a reference coordinate system.

Constructor Detail

TupleQuantity

protected TupleQuantity(java.lang.String name,
                        ScalarQuantity[] scalars)
                 throws visad.VisADException

Constructs from a name and scalar quantities. The default coordinate system transformation will be null.

Parameters:

name - The name for the tuple quantity.

scalars - The scalar quantities.

Throws:

visad.VisADException - VisAD failure.

TupleQuantity

protected TupleQuantity(java.lang.String name,
                        ScalarQuantity[] scalars,
                        visad.CoordinateSystem coordSys)
                 throws visad.VisADException

Constructs from a name, scalar quantities, and a default coordinate system transformation. The default domain set will be null.

Parameters:

name - The name for the tuple quantity.

scalars - The scalar quantitites.

coordSys - The default coordinate system transformation. May be null.

Throws:

visad.VisADException - VisAD failure.

TupleQuantity

protected TupleQuantity(java.lang.String name,
                        ScalarQuantity[] scalars,
                        visad.CoordinateSystem coordSys,
                        visad.Set domain)
                 throws visad.TypeException,
                        visad.VisADException

Constructs from a name, scalar quantities, a default coordinate system transformation, and a default domain set. This is the most general constructor.

Parameters:

name - The name for the tuple quantity.

scalars - The scalar quantitites.

coordSys - The default coordinate system transformation. May be null.

domain - The default domain set. May be null.

Throws:

visad.TypeException - The quantity already exists.

visad.VisADException - VisAD failure.

Method Detail

getRealTypes

protected static visad.RealType[] getRealTypes(ScalarQuantity[] scalars)

Returns an array of VisAD RealTypes corresponding to an array of scalar quantitities.

Parameters:

scalars - An array of the scalar quantities.

Returns:

A corresponding aray of VisAD RealTypes
