Class InteriorIntersectionFinderAdder

java.lang.Object

com.vividsolutions.jts.noding.InteriorIntersectionFinderAdder

All Implemented Interfaces:

SegmentIntersector

public class InteriorIntersectionFinderAdder
extends Object
implements SegmentIntersector

Finds interior intersections between line segments in NodedSegmentStrings, and adds them as nodes using NodedSegmentString.addIntersection(LineIntersector, int, int, int).

This class is used primarily for Snap-Rounding. For general-purpose noding, use IntersectionAdder.

Constructor Detail

InteriorIntersectionFinderAdder

public InteriorIntersectionFinderAdder(LineIntersector li)

Creates an intersection finder which finds all proper intersections

Parameters:

li - the LineIntersector to use

Method Detail

getInteriorIntersections

public List getInteriorIntersections()

processIntersections

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

public boolean isDone()

Always process all intersections

Specified by:

isDone in interface SegmentIntersector
