Hierarchy: Object , EdgeSetIntersector

Direct Known Subclasses: SimpleSweepLineIntersector, SimpleMCSweepLineIntersector, SimpleEdgeSetIntersector

public abstract class EdgeSetIntersector

An EdgeSetIntersector computes all the intersections between the edges in the set. It adds the computed intersections to each edge they are found on. It may be used in two scenarios:

determining the internal intersections between a single set of edges
determining the mutual intersections between two different sets of edges

It uses a SegmentIntersector to compute the intersections between segments and to record statistics about what kinds of intersections were found.

public EdgeSetIntersector()

public abstract abstract void computeIntersections(List edges, SegmentIntersector si, boolean testAllSegments)

Computes all self-intersections between edges in a set of edges, allowing client to choose whether self-intersections are computed.

Parameters:: edges - edges a list of edges to test for intersections; si - si the SegmentIntersector to use; testAllSegments - testAllSegments true if self-intersections are to be tested as well

public abstract abstract void computeIntersections(List edges0, List edges1, SegmentIntersector si)

Computes all mutual intersections between two sets of edges.
