Class XYShape

java.lang.Object

org.apache.lucene.document.XYShape

public class XYShape
extends Object

A cartesian shape utility class for indexing and searching geometries whose vertices are unitless x, y values.

This class defines seven static factory methods for common indexing and search operations:

• createIndexableFields(String, XYPolygon) for indexing a cartesian polygon.
• createIndexableFields(String, XYLine) for indexing a cartesian linestring.
• createIndexableFields(String, float, float) for indexing a x, y cartesian point.
• newBoxQuery() for matching cartesian shapes that have some ShapeField.QueryRelation with a bounding box.
• newLineQuery() for matching cartesian shapes that have some ShapeField.QueryRelation with a linestring.
• newPolygonQuery() for matching cartesian shapes that have some ShapeField.QueryRelation with a polygon.
• newGeometryQuery() for matching cartesian shapes that have some ShapeField.QueryRelation with one or more XYGeometry.

WARNING: Like LatLonPoint, vertex values are indexed with some loss of precision from the original double values.

• LatLonDocValuesField
