- org.locationtech.jts.algorithm.locate.IndexedPointInAreaLocator

All Implemented Interfaces:

PointOnGeometryLocator
```
public class IndexedPointInAreaLocator
extends java.lang.Object
implements PointOnGeometryLocator
```
Determines the Location of Coordinates relative to an areal geometry, using indexing for efficiency. This algorithm is suitable for use in cases where many points will be tested against a given area.
The Location is computed precisely, in that points located on the geometry boundary or segments will return Location.BOUNDARY.
Polygonal and LinearRing geometries are supported. Thread-safe and immutable.
