              visad.RealTuple
                  visad.georef.EarthLocationLite

All Implemented Interfaces:

Serializable, Cloneable, Data, EarthLocation, LatLonPoint, RealTupleIface, Thing, TupleIface

public class EarthLocationLite
extends RealTuple
implements EarthLocation

This provides a LoCal EarthLocation that is much faster to create than the EarthLocationTuple. Assumes units of lat/lon are degrees and Altitude is meters.

Specified by:

getLatLonPoint in interface EarthLocation

Returns:

this

getComponent

public Data getComponent(int i)
                  throws VisADException,
                         RemoteException

Get the i'th component.

Specified by:

getComponent in interface TupleIface

Overrides:

getComponent in class Tuple

Parameters:

i - Which one

Returns:

The component

RemoteException - On badness

VisADException - On badness

getComponents

public Data[] getComponents(boolean copy)

Create, if needed, and return the component array.

Overrides:

getComponents in class Tuple

Parameters:

copy - if true then return a copy of the tuple array. Else return the actual array

Returns:
