ilog.views.maps

Class IlvCoordinate

java.lang.Object

ilog.views.maps.IlvCoordinate

All Implemented Interfaces:

Serializable, Cloneable

public final class IlvCoordinate
extends Object
implements Cloneable, Serializable

An IlvCoordinate is a point defined by two values in double precision. The class IlvCoordinate is the basic data structure for computing projections.

The x and y values designate either the Cartesian coordinates resulting from a forward projection or the latitude and the longitude obtained by inverse computation.

This class is in the ilog.views.maps package since Rogue Wave JViews 3.0. In Rogue Wave JViews 2.x the IlvCoordinate class was located in the ilog.views.maps.projection package.
