## com.vividsolutions.jts.operation.relate
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()` generalized spatial predicate on two `Geometry`s. The class supports specifying a custom `BoundaryNodeRule` to be used during the relate computation.

If named spatial predicates are used on the result `IntersectionMatrix` of the RelateOp, the result may or not be affected by the choice of `BoundaryNodeRule`, depending on the exact nature of the pattern. For instance, `IntersectionMatrix.isIntersects()` is insensitive to the choice of `BoundaryNodeRule`, whereas `IntersectionMatrix.isTouches(int, int)` is affected by the rule chosen.

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.
