Enum Constant Detail

HAVERSINE

public static final GeoCalculator.Algorithm HAVERSINE
The Haversine algorithm -- assumes a spherical Earth.


ANDOYER

public static final GeoCalculator.Algorithm ANDOYER
As per Haversine, but uses the better Andoyer method for distance.


VINCENTY

public static final GeoCalculator.Algorithm VINCENTY
The very accurate but slow Vincenty method.

Method Detail

values

public static GeoCalculator.Algorithm[] values()
Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
for (GeoCalculator.Algorithm c : GeoCalculator.Algorithm.values())
    System.out.println(c);

Returns:
an array containing the constants of this enum type, in the order they are declared

valueOf

public static GeoCalculator.Algorithm valueOf(java.lang.String name)
Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:
name - the name of the enum constant to be returned.
Returns:
the enum constant with the specified name
Throws:
java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
java.lang.NullPointerException - if the argument is null
