Class PointLocator
java.lang.Object
com.vividsolutions.jts.algorithm.PointLocator
public class PointLocator
- extends java.lang.Object
Computes the topological (Location
)
of a single point to a Geometry
.
A 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:
LinearRing
s do not enclose any area - points inside the ring are still in the EXTERIOR of the ring.
Instances of this class are not reentrant.

PointLocator
public PointLocator()
PointLocator
public PointLocator(BoundaryNodeRule boundaryRule)
intersects
public boolean intersects(Coordinate p,
Geometry geom)
- Convenience method to test a point for intersection with
a Geometry
- Parameters:
p
- the coordinate to testgeom
- the Geometry to test
- Returns:
true
if the point is in the interior or boundary of the Geometry
locate
public int locate(Coordinate p,
Geometry geom)
- Computes the topological relationship (
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.
- Returns:
- the
Location
of the point relative to the input Geometry
