addSplitEdges method
Creates new edges for all the edges that the intersections in this list split the parent edge into. Adds the edges to the provided argument list (this is so a single list can be used to accumulate all split edges for a set of {@link SegmentString}s).
Implementation
void addSplitEdges(List edgeList) {
// ensure that the list has entries for the first and last point of the edge
addEndpoints();
addCollapsedNodes();
Iterator it = iterator();
// there should always be at least two entries in the list, since the endpoints are nodes
it.moveNext();
SegmentNode eiPrev = it.current;
while (it.moveNext()) {
SegmentNode ei = it.current;
SegmentString newEdge = createSplitEdge(eiPrev, ei);
/*
if (newEdge.size() < 2)
throw new RuntimeException("created single point edge: " + newEdge.toString());
*/
edgeList.add(newEdge);
eiPrev = ei;
}
