Class LatLonShapeLineQuery

java.lang.Object

org.apache.lucene.search.Query

org.apache.lucene.document.LatLonShapeQuery

org.apache.lucene.document.LatLonShapeLineQuery

final class LatLonShapeLineQuery
extends LatLonShapeQuery

Finds all previously indexed shapes that intersect the specified arbitrary Line.

Note:

• QueryRelation.WITHIN queries are not yet supported
• Dateline crossing is not yet supported

todo:

• Add distance support for buffered queries

The field must be indexed using LatLonShape.createIndexableFields(java.lang.String, org.apache.lucene.geo.Polygon) added per document.
