Detailed Description

Implements the SFS relate() operation on two geom::Geometry objects.

This class supports specifying a custom algorithm::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.
