public class PreparedPolygonContainsProperly

extends PreparedPolygonPredicate

Computes the containsProperly spatial relationship predicate for PreparedPolygons relative to all other Geometry classes. Uses short-circuit tests and indexing to improve performance.

A Geometry A containsProperly another Geometry B iff all points of B are contained in the Interior of A. Equivalently, B is contained in A AND B does not intersect the Boundary of A.

The advantage to using this predicate is that it can be computed efficiently, with no need to compute topology at individual points. In a situation with many geometries intersecting the boundary of the target geometry, this can make a performance difference.
