Constructor Detail

SnappingIntersectionAdder

public SnappingIntersectionAdder(double snapTolerance,
                                 SnappingPointIndex snapPointIndex)

Creates an intersector which finds intersections, snaps them, and adds them as nodes.

Parameters:

snapTolerance - the snapping tolerance distance

snapPointIndex - the snapPointIndex

Method Detail

processIntersections

public void processIntersections(SegmentString seg0,
                                 int segIndex0,
                                 SegmentString seg1,
                                 int segIndex1)

This method is called by clients of the SegmentIntersector class to process intersections for two segments of the SegmentStrings being intersected. Note that some clients (such as MonotoneChains) may optimize away this call for segment pairs which they have determined do not intersect (e.g. by an disjoint envelope test).
