Class IndexedPointInAreaLocator

java.lang.Object

com.revolsys.jts.algorithm.locate.IndexedPointInAreaLocator

All Implemented Interfaces:

PointOnGeometryLocator

Direct Known Subclasses:

GeometryFactoryIndexedPointInAreaLocator

public class IndexedPointInAreaLocator
extends Object
implements PointOnGeometryLocator

Determines the Location of Coordinatess relative to a Polygonal geometry, using indexing for efficiency. This algorithm is suitable for use in cases where many points will be tested against a given area. Thread-safe and immutable.
