Interface PlanetaryTheory

All Known Implementing Classes:

ELP82, Pluto99, VSOP87

public interface PlanetaryTheory

Interface to be implemented by classes which compute planetary positions
This interface is empty because java doesn't allow to specify static methods in interfaces. But all implementing classes of JEphem provide a method :
public static double getPrecision(int bodyIndex, double jd);

This interface is also used to define constants identifying planetary theories.

Field Summary

static int	ELP82 Constant identifying ELP82b-2000 planetary theory.
static int	PLUTO99 Constant identifying Pluto99 planetary theory.
static java.lang.String[]	THEORY_NAMES Array containing English names of planetary theories.
static int	VSOP87A_FULL Constant identifying full precision version of VSOP87A planetary theory.
