Class DoubleTuple

java.lang.Object

visad.ThingImpl

visad.DataImpl

visad.Tuple

visad.RealTuple

visad.DoubleTuple

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, Data, RealTupleIface, Thing, TupleIface

public class DoubleTuple
extends RealTuple

This provides a LoCal RealTuple that can hold numeric values without taking the hit that having lots and lots of Real objects around.

Method Detail

isMissing

public boolean isMissing()

Check if there is no Data in this Tuple.

Specified by:

isMissing in interface Data

Specified by:

isMissing in interface TupleIface

Overrides:

isMissing in class Tuple

Returns:

true if there is no data.

getComponent

public Data getComponent(int i)
                  throws VisADException,
                         java.rmi.RemoteException

Get the i'th component. This creates it if needed and stores it in the components array

Specified by:

getComponent in interface TupleIface

Overrides:

getComponent in class Tuple

Parameters:

i - Which one

Returns:

The component

Throws:

java.rmi.RemoteException - On badness
