Class GeometryLocation

Represents the location of a point on a Geometry. Maintains both the actual point location (which may not be exact, if the point is not a vertex) as well as information about the component and segment index where the point occurs. Locations inside area Geometrys will not have an associated segment index, so in this case the segment index will have the sentinel value of InsideArea.

Syntax

public class GeometryLocation

Constructors

GeometryLocation(Geometry, Coordinate)

Constructs a GeometryLocation specifying a point inside an area point.

Declaration

public GeometryLocation(Geometry component, Coordinate pt)

Parameters

Type	Name	Description
Geometry	component	The component of the geometry containing the point
Coordinate	pt	The coordinate of the location

GeometryLocation(Geometry, Int32, Coordinate)

Constructs a GeometryLocation specifying a point on a point, as well as the segment that the point is on (or InsideArea if the point is not on a segment).

Declaration

public GeometryLocation(Geometry component, int segIndex, Coordinate pt)

Parameters

Type	Name	Description
Geometry	component	The component of the geometry containing the point
Int32	segIndex	The segment index of the location, or InsideArea
Coordinate	pt	The coordinate of the location

Fields

InsideArea

A special value of segmentIndex used for locations inside area geometries. These locations are not located on a segment, and thus do not have an associated segment index.

Declaration

public const int InsideArea = -1

Field Value

Type	Description
Int32

Properties

Coordinate

Returns the Coordinate of this location.

Declaration

public Coordinate Coordinate { get; }

Property Value

Type	Description
Coordinate

GeometryComponent

Returns the geometry component on (or in) which this location occurs.

Declaration

public Geometry GeometryComponent { get; }

Property Value

Type	Description
Geometry

IsInsideArea

Tests whether this location represents a point inside an area geometry.

Declaration

public bool IsInsideArea { get; }

Property Value

Type	Description
Boolean

SegmentIndex

Returns the segment index for this location. If the location is inside an area, the index will have the value InsideArea.

Declaration

public int SegmentIndex { get; }

Property Value

Type	Description
Int32
