PointLocator

java.lang.Object
- org.meteoinfo.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:
- LinearRings do not enclose any area - points inside the ring are still in the EXTERIOR of the ring.
Instances of this class are not reentrant.

```
    Convenience method to test a point for intersection with a Geometry
    
    Parameters:
    
    p - the coordinate to test
    
    geom - 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
