Syntax

public sealed class SnappingIntersectionAdder : ISegmentIntersector

Constructors

SnappingIntersectionAdder(double, SnappingPointIndex)

Creates an intersector which finds all snapped intersections, and adds them as nodes.

Declaration

public SnappingIntersectionAdder(double snapTolerance, SnappingPointIndex snapPointIndex)

Parameters

Type	Name	Description
double	snapTolerance	The snapping tolerance distance
SnappingPointIndex	snapPointIndex	A snap index to use

SnappingIntersectionAdder(double, SnappingPointIndex, ElevationModel)

Creates an intersector which finds all snapped intersections, and adds them as nodes.

Declaration

public SnappingIntersectionAdder(double snapTolerance, SnappingPointIndex snapPointIndex, ElevationModel em)

Parameters

Type	Name	Description
double	snapTolerance	The snapping tolerance distance
SnappingPointIndex	snapPointIndex	A snap index to use
ElevationModel	em	An elevation model. May be null

Properties

IsDone

Reports whether the client of this class needs to continue testing all intersections in an arrangement.

Declaration

public bool IsDone { get; }

Property Value

Type	Description
bool	if there is no need to continue testing segments

Remarks

Always process all intersections

Methods

ProcessIntersections(ISegmentString, int, ISegmentString, int)

This method is called by clients of the ISegmentIntersector class to process intersections for two segments of the ISegmentStrings being intersected. Note that some clients (such as MonotoneChains) may optimize away this call for segment pairs which they have determined do not intersect (e.g. by an disjoint envelope test).

Declaration

public void ProcessIntersections(ISegmentString seg0, int segIndex0, ISegmentString seg1, int segIndex1)

Parameters

Type	Name	Description
ISegmentString	seg0
int	segIndex0
ISegmentString	seg1
int	segIndex1

Implements

ISegmentIntersector
