Interface LatLonPoint

public interface LatLonPoint

Points on the Earth's surface, represented as (longitude,latitude), in units of degrees. Longitude is always between -180 and +180 deg. Latitude is always between -90 and +90 deg. TODO will be an Immutable class in ver6

Method Summary

Modifier and Type	Method and Description
static LatLonPoint	create() Standard way to create a "default" LatLonPoint.
static LatLonPoint	create(double lat, double lon) Standard way to create a LatLonPoint.
double	getLatitude() Returns the latitude, between +/- 90 degrees.
double	getLongitude() Returns the longitude, between +/-180 degrees
default boolean	nearlyEquals(LatLonPoint that) Returns the result of nearlyEquals(LatLonPoint, double), with Misc.defaultMaxRelativeDiffDouble.
boolean	nearlyEquals(LatLonPoint that, double maxRelDiff) Returns true if this point is nearly equal to that.

Method Detail

create

static LatLonPoint create()

Standard way to create a "default" LatLonPoint.

create

static LatLonPoint create(double lat,
                          double lon)

Standard way to create a LatLonPoint.

getLatitude

double getLatitude()

Returns the latitude, between +/- 90 degrees.

Returns:

latitude (degrees)

getLongitude

double getLongitude()

Returns the longitude, between +/-180 degrees

Returns:

longitude (degrees)

nearlyEquals

default boolean nearlyEquals(LatLonPoint that)

Returns the result of nearlyEquals(LatLonPoint, double), with Misc.defaultMaxRelativeDiffDouble.

nearlyEquals

boolean nearlyEquals(LatLonPoint that,
                     double maxRelDiff)

Returns true if this point is nearly equal to that. The "near equality" of points is determined using Misc.nearlyEquals(double, double, double), with the specified maxRelDiff.

Parameters:

that - the other point to check.

maxRelDiff - the maximum relative difference the two points may have.

Returns:

true if this point is nearly equal to that.
