Subject Re: More Spatial Relations

Hi Bingtao,

shape to binary format(e.g. wkb) and fall back to jts?

Yes.  There's a lot already there but you'd need to subclass some stuff to
add some other predicates.  See CompositeSpatialStrategy and
ShapeValuesPredicate.  You could cast the value, a Shape, to a JtsGeometry
(a Spatial4j shape) and then call getGeom() to get the underlying JTS
Geometry instance.  If you find you need to fork entire classes then feel
free to suggest improvements to the extensibility.
