Interface SegmentIntersector

All Known Implementing Classes:

InteriorIntersectionFinder, IntersectionAdder, IntersectionFinderAdder, LineIntersectionAdder, SegmentIntersectionDetector

public interface SegmentIntersector

Processes possible intersections detected by a Noder. The SegmentIntersector is passed to a Noder. The addIntersections method is called whenever the Noder detects that two SegmentStrings might intersect. This class may be used either to find all intersections, or to detect the presence of an intersection. In the latter case, Noders may choose to short-circuit their computation by calling the isDone method. This class is an example of the Strategy pattern.

Method Summary

boolean	isDone() Reports whether the client of this class needs to continue testing all intersections in an arrangement.
void	processIntersections(SegmentString e0, int segIndex0, SegmentString e1, int segIndex1) This method is called by clients of the SegmentIntersector interface to process intersections for two segments of the SegmentStrings being intersected.

Method Detail

processIntersections

public void processIntersections(SegmentString e0,
                                 int segIndex0,
                                 SegmentString e1,
                                 int segIndex1)

This method is called by clients of the SegmentIntersector interface to process intersections for two segments of the SegmentStrings being intersected.

isDone

public boolean isDone()

Reports whether the client of this class needs to continue testing all intersections in an arrangement.

Returns:

true if there is no need to continue testing segments
