Package org.locationtech.jts.geomgraph

Class EdgeIntersection

java.lang.Object

org.locationtech.jts.geomgraph.EdgeIntersection

All Implemented Interfaces:

Comparable

public class EdgeIntersection
extends Object
implements Comparable

Represents a point on an edge which intersects with another edge.

The intersection may either be a single point, or a line segment (in which case this point is the start of the line segment) The intersection point must be precise.

Version:

1.7
