Syntax

public class EdgeIntersectionList

Constructors

EdgeIntersectionList(Edge)

Declaration

public EdgeIntersectionList(Edge edge)

Parameters

Type	Name	Description
Edge	edge

Properties

Count

Declaration

public int Count { get; }

Property Value

Type	Description
int

Methods

Add(Coordinate, int, double)

Adds an intersection into the list, if it isn't already there. The input segmentIndex and dist are expected to be normalized.

Declaration

public EdgeIntersection Add(Coordinate intPt, int segmentIndex, double dist)

Parameters

Type	Name	Description
Coordinate	intPt	The point of intersection
int	segmentIndex	The index of the containing line segment in the parent edge
double	dist	The edge distance of this point along the containing line segment

Returns

Type	Description
EdgeIntersection	The EdgeIntersection found or added.

AddEndpoints()

Adds entries for the first and last points of the edge to the list.

Declaration

public void AddEndpoints()

AddSplitEdges(IList<Edge>)

Creates new edges for all the edges that the intersections in this list split the parent edge into. Adds the edges to the input list (this is so a single list can be used to accumulate all split edges for a Geometry).

Declaration

public void AddSplitEdges(IList<Edge> edgeList)

Parameters

Type	Name	Description
IList<Edge>	edgeList

CreateSplitEdge(EdgeIntersection, EdgeIntersection)

Create a new "split edge" with the section of points between (and including) the two intersections. The label for the new edge is the same as the label for the parent edge.

Declaration

public Edge CreateSplitEdge(EdgeIntersection ei0, EdgeIntersection ei1)

Parameters

Type	Name	Description
EdgeIntersection	ei0
EdgeIntersection	ei1

Returns

Type	Description
Edge

GetEnumerator()

Returns an iterator of EdgeIntersections.

Declaration

public IEnumerator<EdgeIntersection> GetEnumerator()

Returns

Type	Description
IEnumerator<EdgeIntersection>

IsIntersection(Coordinate)

Declaration

public bool IsIntersection(Coordinate pt)

Parameters

Type	Name	Description
Coordinate	pt

Returns

Type	Description
bool

Write(StreamWriter)

Declaration

public void Write(StreamWriter outstream)

Parameters

Type	Name	Description
StreamWriter	outstream
