Class EdgeSetIntersector

Known Direct Subclasses:
SimpleEdgeSetIntersector, SimpleMCSweepLineIntersector, SimpleSweepLineIntersector

public abstract class EdgeSetIntersector
extends java.lang.Object

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: It uses a SegmentIntersector to compute the intersections between segments and to record statistics about what kinds of intersections were found.
Version:
1.6

Constructor Summary

EdgeSetIntersector()

Method Summary

abstract void
computeIntersections(List edges0, List edges1, SegmentIntersector si)
Computes all mutual intersections between two sets of edges.
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.

Method Details

computeIntersections

public abstract void computeIntersections(List edges0,
                                          List edges1,
                                          SegmentIntersector si)
Computes all mutual intersections between two sets of edges.

computeIntersections

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