IntersectionAdder class

Computes the possible intersections between two line segments in {@link NodedSegmentString}s and adds them to each string using {@link NodedSegmentString#addIntersection(LineIntersector, int, int, int)}.

Methods

getLineIntersector() LineIntersector
getProperIntersectionPoint() Coordinate?
@return the proper intersection point, or null if none was found
hasInteriorIntersection() bool
An interior intersection is an intersection which is in the interior of some segment.
hasIntersection() bool
hasProperInteriorIntersection() bool
A proper interior intersection is a proper intersection which is not contained in the set of boundary nodes set for this SegmentIntersector.
hasProperIntersection() bool
A proper intersection is an intersection which is interior to at least two line segments. Note that a proper intersection is not necessarily in the interior of the entire Geometry, since another edge may have an endpoint equal to the intersection, which according to SFS semantics can result in the point being on the Boundary of the Geometry.
isDone() bool
Always process all intersections
override
isTrivialIntersection(SegmentString e0, int segIndex0, SegmentString e1, int segIndex1) bool
A trivial intersection is an apparent self-intersection which in fact is simply the point shared by adjacent line segments. Note that closed edges require a special check for the point shared by the beginning and end segments.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
processIntersections(SegmentString e0, int segIndex0, SegmentString e1, int segIndex1) → void
This method is called by clients of the {@link SegmentIntersector} class to process intersections for two segments of the {@link SegmentString}s 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).
override
toString() String
A string representation of this object.
