Class Line

java.lang.Object

org.apache.lucene.geo.LatLonGeometry

org.apache.lucene.geo.Line

public class Line
extends LatLonGeometry

Represents a line on the earth's surface. You can construct the Line directly with double[] coordinates.

NOTES:

1. All latitude/longitude values must be in decimal degrees.
2. For more advanced GeoSpatial indexing and query operations see the spatial-extras module
