computeEdgeEndsWithEdge method
Creates stub edges for all the intersections in this Edge (if any) and inserts them into the graph.
Implementation
void computeEdgeEndsWithEdge(Edge edge, List l) {
EdgeIntersectionList eiList = edge.getEdgeIntersectionList();
//Debug.print(eiList);
// ensure that the list has entries for the first and last point of the edge
eiList.addEndpoints();
Iterator it = eiList.iterator();
EdgeIntersection? eiPrev = null;
EdgeIntersection? eiCurr = null;
// no intersections, so there is nothing to do
if (!it.moveNext()) return;
EdgeIntersection? eiNext = it.current as EdgeIntersection;
do {
eiPrev = eiCurr;
eiCurr = eiNext;
eiNext = null;
if (it.moveNext()) eiNext = it.current as EdgeIntersection;
if (eiCurr != null) {
createEdgeEndForPrev(edge, l, eiCurr, eiPrev);
createEdgeEndForNext(edge, l, eiCurr, eiNext);
}
} while (eiCurr != null);
}
