PointLocator class
Computes the topological ({@link Location}) of a single point to a {@link Geometry}. A {@link BoundaryNodeRule} may be specified to control the evaluation of whether the point lies on the boundary or not The default rule is to use the the SFS Boundary Determination Rule
Notes:
- {@link LinearRing}s do not enclose any area - points inside the ring are still in the EXTERIOR of the ring.

Methods
-
computeLocation(
Coordinate p, Geometry geom) → void -
intersects(
Coordinate p, Geometry geom) → bool -
Convenience method to test a point for intersection with
a Geometry
@param p the coordinate to test
@param geom the Geometry to test
@return
true
if the point is in the interior or boundary of the Geometry -
locate(
Coordinate p, Geometry geom) → int - Computes the topological relationship ({@link Location}) of a single point to a Geometry. It handles both single-element and multi-element Geometries. The algorithm for multi-part Geometries takes into account the SFS Boundary Determination Rule.
-
locateInPolygon(
Coordinate p, Polygon poly) → int -
locateInPolygonRing(
Coordinate p, LinearRing ring) → int -
locateOnLineString(
Coordinate p, LineString l) → int -
locateOnPoint(
Coordinate p, Point pt) → int -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.

toString(
) → String -
A string representation of this object.

Operators
-
operator ==(
Object other) → bool -
The equality operator.
