```
public abstract class FeatureTableCoreIndex
extends BaseExtension
```
Abstract core Feature Table Index NGA Extension implementation. This extension is used to index Geometries within a feature table by their minimum bounding box for bounding box queries. This extension is required to provide an index implementation when a SQLite version is used before SpatialLite support (Android).
