SegmentIntersector.addIntersections
(Edge e0, int segIndex0, Edge e1, int segIndex1) This method is called by clients of the EdgeIntersector class to test for and add intersections for two segments of the edges being intersected.private void

SegmentIntersector.isTrivialIntersection
(Edge e0, int segIndex0, Edge e1, int segIndex1) A trivial intersection is an apparent self-intersection which in fact is simply the point shared by adjacent line segments.Constructors in org.locationtech.jts.geomgraph.index with parameters of type Edge -
