Class Line

java.lang.Object
org.apache.lucene.geo.Geometry
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
