All Implemented Interfaces:
  `IndexableField`

public final class XYShapeDocValuesField extends ShapeDocValuesField
Concrete implementation of a `ShapeDocValuesField` for cartesian geometries.

This field should be instantiated through `XYShape.createDocValueField(String, XYLine)`

- `XYShape.createDocValueField(String, XYPolygon)` for indexing a cartesian polygon doc value field.
- `XYShape.createDocValueField(String, XYLine)` for indexing a cartesian linestring doc value.
- `XYShape.createDocValueField(String, float, float)` for indexing a x, y cartesian point doc value.
- `XYShape.createDocValueField(String, List)` for indexing a cartesian doc value from a precomputed tessellation.
- `XYShape.createDocValueField(String, BytesRef)` for indexing a cartesian doc value from existing encoding.

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

  - `PointValues`
  - `XYDocValuesField`
WARNING: This API is experimental and might change in incompatible ways in the next release.
