Enclosing class:

BoundaryCrossing

public static class BoundaryCrossing.CrossingIntersection
extends Intersection

A Intersection class that knows how to call BoundaryCrossing.Collector to keep track of the path's relationship with the regions.

Method Detail

considerSegmentXRegion

public boolean considerSegmentXRegion(GeoSegment segment,
                                      GeoRegion region)

Calls Intersection.isSegmentNearRegion() to see if segment is near the region. We're going to assume that this is going to be called with segments ordered as they appear in the path, in case the path is kinda crazy, and then we can keep track of the crossings in the right order.

Overrides:

considerSegmentXRegion in class Intersection

Returns:

true if segment intersects region
