A base class for PreparedGeometry subclasses.
Contains default implementations for methods, which simply delegate to the equivalent Geometry methods. This class may be used as a "no-op" class for Geometry types which do not have a corresponding PreparedGeometry implementation.
bool geos::geom::prep::BasicPreparedGeometry::contains | ( | const geom::Geometry * | g | ) | const [virtual] |
Default implementation.
Implements geos::geom::prep::PreparedGeometry.
Reimplemented in geos::geom::prep::PreparedPolygon.
bool geos::geom::prep::BasicPreparedGeometry::containsProperly | ( | const geom::Geometry * | g | ) | const [virtual] |
Default implementation.
Implements geos::geom::prep::PreparedGeometry.
Reimplemented in geos::geom::prep::PreparedPolygon.
bool geos::geom::prep::BasicPreparedGeometry::coveredBy | ( | const geom::Geometry * | g | ) | const [virtual] |
Default implementation.
Implements geos::geom::prep::PreparedGeometry.
bool geos::geom::prep::BasicPreparedGeometry::covers | ( | const geom::Geometry * | g | ) | const [virtual] |
Default implementation.
Implements geos::geom::prep::PreparedGeometry.
Reimplemented in geos::geom::prep::PreparedPolygon.
bool geos::geom::prep::BasicPreparedGeometry::crosses | ( | const geom::Geometry * | g | ) | const [virtual] |
Default implementation.
Implements geos::geom::prep::PreparedGeometry.
bool geos::geom::prep::BasicPreparedGeometry::disjoint | ( | const geom::Geometry * | g | ) | const [virtual] |
Standard implementation for all geometries. Supports GeometryCollections as input.
Implements geos::geom::prep::PreparedGeometry.
bool geos::geom::prep::BasicPreparedGeometry::envelopeCovers | ( | const geom::Geometry * | g | ) | const [protected] |
bool geos::geom::prep::BasicPreparedGeometry::envelopesIntersect | ( | const geom::Geometry * | g | ) | const [protected] |
const geom::Geometry& geos::geom::prep::BasicPreparedGeometry::getGeometry | ( | ) | const [inline, virtual] |
Gets the original Geometry which has been prepared.
Implements geos::geom::prep::PreparedGeometry.
const Coordinate::ConstVect* geos::geom::prep::BasicPreparedGeometry::getRepresentativePoints | ( | ) | const [inline] |
Gets the list of representative points for this geometry. One vertex is included for every component of the geometry (i.e. including one for every ring of polygonal geometries)
bool geos::geom::prep::BasicPreparedGeometry::intersects | ( | const geom::Geometry * | g | ) | const [virtual] |
Default implementation.
Implements geos::geom::prep::PreparedGeometry.
Reimplemented in geos::geom::prep::PreparedLineString, and geos::geom::prep::PreparedPolygon.
bool geos::geom::prep::BasicPreparedGeometry::isAnyTargetComponentInTest | ( | const geom::Geometry * | testGeom | ) | const |
Tests whether any representative of the target geometry intersects the test geometry. This is useful in A/A, A/L, A/P, L/P, and P/P cases.
geom | the test geometry | |
repPts | the representative points of the target geometry |
bool geos::geom::prep::BasicPreparedGeometry::overlaps | ( | const geom::Geometry * | g | ) | const [virtual] |
Default implementation.
Implements geos::geom::prep::PreparedGeometry.
void geos::geom::prep::BasicPreparedGeometry::setGeometry | ( | const geom::Geometry * | geom | ) | [protected] |
Sets the original Geometry which will be prepared.
bool geos::geom::prep::BasicPreparedGeometry::touches | ( | const geom::Geometry * | g | ) | const [virtual] |
Default implementation.
Implements geos::geom::prep::PreparedGeometry.
bool geos::geom::prep::BasicPreparedGeometry::within | ( | const geom::Geometry * | g | ) | const [virtual] |
Default implementation.
Implements geos::geom::prep::PreparedGeometry.
