org.apache.lucene.spatial.util.ShapeFieldCache<T>

public class ShapeFieldCache<T extends org.locationtech.spatial4j.shape.Shape>
extends Object

Bounded Cache of Shapes associated with docIds. Note, multiple Shapes can be associated with a given docId.

WARNING: This class holds the data in an extremely inefficient manner as all Points are in memory as objects and they are stored in many ArrayLists (one per document). So it works but doesn't scale. It will be replaced in the future.

NOTE: This API is for internal purposes only and might change in incompatible ways in the next release.
