Class SimplePointInAreaLocator

java.lang.Object

com.vividsolutions.jts.algorithm.locate.SimplePointInAreaLocator

All Implemented Interfaces:

PointOnGeometryLocator

public class SimplePointInAreaLocator
extends Object
implements PointOnGeometryLocator

Computes the location of points relative to a Polygonal Geometry, using a simple O(n) algorithm. This algorithm is suitable for use in cases where only one or a few points will be tested against a given area.

The algorithm used is only guaranteed to return correct results for points which are not on the boundary of the Geometry.

public SimplePointInAreaLocator(Geometry geom)

Method Detail

locate

public static int locate(Coordinate p,
                         Geometry geom)

Determines the Location of a point in an areal Geometry. Currently this will never return a value of BOUNDARY.

Parameters:

p - the point to test

geom - the areal geometry to test

Returns:

the Location of the point in the geometry

containsPointInPolygon

public static boolean containsPointInPolygon(Coordinate p,
                                             Polygon poly)

locate

public int locate(Coordinate p)

Description copied from interface: PointOnGeometryLocator

Determines the Location of a point in the Geometry.

Specified by:

locate in interface PointOnGeometryLocator

Parameters:

p - the point to test

Returns:

the location of the point in the geometry
