Class DisjointSpatialFilter

A Spatial Filter implementing IsDisjointTo in terms of a SpatialStrategy's support for Intersects. A document is considered disjoint if it has spatial data that does not intersect with the query shape. Another way of looking at this is that it's a way to invert a query shape.
