Class SegmentIntersectionDetector

Detects and records an intersection between two ISegmentStrings, if one exists. Only a single intersection is recorded.

Namespace: NetTopologySuite.Noding
Assembly: NetTopologySuite.dll
Syntax
public class SegmentIntersectionDetector : ISegmentIntersector
Remarks

This strategy can be configured to search for proper intersections. In this case, the presence of any intersection will still be recorded, but searching will continue until either a proper intersection has been found or no intersections are detected.

IntersectionSegments

Gets the endpoints of the intersecting segments.

IsDone

Tests whether processing can terminate, because all required information has been obtained (e.g. an intersection of the desired type has been detected).

Declaration
public bool IsDone { get; }
Property Value
Type Description
Boolean

Methods

| Improve this Doc View Source

ProcessIntersections(ISegmentString, Int32, ISegmentString, Int32)

This method is called by clients of the ISegmentIntersector class to process intersections for two segments of the ISegmentStrings being intersected.

Declaration
public void ProcessIntersections(ISegmentString e0, int segIndex0, ISegmentString e1, int segIndex1)
Parameters
Type Name Description
ISegmentString e0
Int32 segIndex0
ISegmentString e1
Int32 segIndex1
Remarks

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).
