Class PreparedPolygonContainsProperly


  • 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.

    • Method Detail

      • containsProperly

        public static boolean containsProperly​(PreparedPolygon prep,
                                               Geometry geom)
        Computes the containsProperly predicate between a PreparedPolygon and a Geometry.
        Parameters:
        prep - the prepared polygon
        geom - a test geometry
        Returns:
        true if the polygon properly contains the geometry
      • containsProperly

        public boolean containsProperly​(Geometry geom)
        Tests whether this PreparedPolygon containsProperly a given geometry.
        Parameters:
        geom - the test geometry
        Returns:
        true if the test geometry is contained properly
