Interface GeoPath

All Superinterfaces:

GeoExtent

All Known Subinterfaces:

GeoRegion

All Known Implementing Classes:

GeoIntersectionLayer.OMPolyRegion, GeoPath.Impl, GeoRegion.Impl, OMGeo.Polygon, OMGeo.Polyline

public interface GeoPath
extends GeoExtent

An abstraction of an arbitrary geographic path. A path is assumed to mean a chain of points that although it may share a common starting and end point, it will not not represent an area in that case.

Nested Class Summary

static class	GeoPath.Impl An implementation of Path that takes an alternating lat/lon array and (optionally) an array of altitudes.
static interface	GeoPath.PointIterator
static interface	GeoPath.SegmentIterator

Method Summary

GeoArray	getPoints() Return the points that make up the path as an array of Geo object.
boolean	isSegmentNear(GeoSegment s, double epsilon) Does the segment s come within epsilon (in radians) of us?
int	length()
GeoPath.PointIterator	pointIterator()
GeoPath.SegmentIterator	segmentIterator()

Method Detail

segmentIterator

GeoPath.SegmentIterator segmentIterator()

Returns:

an iterator over the segments of the path *

pointIterator

GeoPath.PointIterator pointIterator()

Returns:

an iterator over the points of the path *

isSegmentNear

boolean isSegmentNear(GeoSegment s,
                      double epsilon)

Does the segment s come within epsilon (in radians) of us?

getPoints

GeoArray getPoints()

Return the points that make up the path as an array of Geo object. Closed paths are not specially marked. Specifically, closed paths do not have equal first and last Geo points in the returned array.

Returns:

the Geo points of the Path

length

int length()

Returns:

the number of points in the path.
