Class RelateOp

java.lang.Object
  com.vividsolutions.jts.operation.GeometryGraphOperation
      com.vividsolutions.jts.operation.relate.RelateOp

public class RelateOp
extends GeometryGraphOperation

Implements the SFS relate() operation on two Geometrys. This class supports specifying a custom BoundaryNodeRule to be used during the relate computation.

Note: custom Boundary Node Rules do not (currently) affect the results of other Geometry methods (such as Geometry.getBoundary(). The results of these methods may not be consistent with the relationship computed by a custom Boundary Node Rule.
