Interface GeodesicString

All Superinterfaces:

CurveSegment, GenericCurve

All Known Subinterfaces:

Geodesic

public interface GeodesicString

extends CurveSegment

Sequence of geodesic segments. The interface essentially combines a Sequence<Geodesic> into a single object, with the obvious savings of storage space.

UML identifier (abstract type): GM_GeodesicString

Method Summary

List<Geodesic>	asGeodesics() Decomposes a geodesic string into an equivalent sequence of geodesic segments.
PointArray	getControlPoints() Returns a sequence of positions between which this GeodesicString is interpolated using geodesics from the geoid or ellipsoid of the coordinate reference system being used.
CurveInterpolation	getInterpolation() The interpolation for a GeodesicString is "geodesic".

Method Detail

getControlPoints

PointArray getControlPoints()

Returns a sequence of positions between which this GeodesicString is interpolated using geodesics from the geoid or ellipsoid of the coordinate reference system being used. The organization of these points is identical to that in LineString.

Returns:

The control points.

UML identifier (operation): controlPoint

getInterpolation

CurveInterpolation getInterpolation()

The interpolation for a GeodesicString is "geodesic".

Specified by:

getInterpolation in interface CurveSegment

Returns:

Always CurveInterpolation.GEODESIC.

UML identifier (operation): interpolation

asGeodesics

List<Geodesic> asGeodesics()

Decomposes a geodesic string into an equivalent sequence of geodesic segments.

Returns:

The equivalent sequence of geodesic segments.

UML identifier (operation): asGM_Geodesic
