java.lang.Object

com.vividsolutions.jts.geomgraph.index.EdgeSetIntersector

com.vividsolutions.jts.geomgraph.index.SimpleEdgeSetIntersector

public class SimpleEdgeSetIntersector
extends EdgeSetIntersector

Finds all intersections in one or two sets of edges, using the straightforward method of comparing all segments. This algorithm is too slow for production use, but is useful for testing purposes.

                        boolean testAllSegments)

Description copied from class: EdgeSetIntersector

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

Specified by:

computeIntersections in class EdgeSetIntersector

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
