org.geotools.geometry.iso.operation.relate.RelateComputer
public class RelateComputer
- extends java.lang.Object
Computes the topological relationship between two Geometries.
RelateComputer does not need to build a complete graph structure to compute
the IntersectionMatrix. The relationship between the geometries can be
computed by simply examining the labelling of edges incident on each node.
RelateComputer does not currently support arbitrary GeometryCollections. This
is because GeometryCollections can contain overlapping Polygons. In order to
correct compute relate on overlapping Polygons, they would first need to be
noded and merged (if not explicitly, at least implicitly).
