Add(Coordinate, Int32, 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
Int32 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
