Class PointLocator

Namespace

NetTopologySuite.Algorithm

Assembly

NetTopologySuite.dll

Computes the topological relationship (Location) of a single point to a Geometry.

object.Equals(object)

object.Equals(object, object)

object.ReferenceEquals(object, object)

object.GetHashCode()

Remarks

A IBoundaryNodeRule may be specified to control the evaluation of whether the point lies on the boundary or not The default rule is to use the SFS Boundary Determination Rule

Notes:

Instances of this class are not reentrant.

Constructors

PointLocator()

Initializes a new instance of the PointLocator class.

The default boundary rule is EndpointBoundaryRule.

public PointLocator()

PointLocator(IBoundaryNodeRule)

Initializes a new instance of the PointLocator class using the provided boundaryRule.

public PointLocator(IBoundaryNodeRule boundaryRule)

Parameters

boundaryRule IBoundaryNodeRule

The boundary rule to use.

Methods

Intersects(Coordinate, Geometry)

Convenience method to test a point for intersection with a Geometry

public bool Intersects(Coordinate p, Geometry geom)

Parameters

p Coordinate

The coordinate to test.

geom Geometry

The Geometry to test.

Returns

bool

true if the point is in the interior or boundary of the Geometry.

Locate(Coordinate, Geometry)

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 boundaryDetermination rule.

public Location Locate(Coordinate p, Geometry geom)

Parameters

p Coordinate

geom Geometry

Returns

Location

The Location of the point relative to the input Geometry.
