Detailed Description

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::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]

Determines whether the envelope of this geometry covers the Geometry g. Parameters: g  a Geometry Returns: true if g is contained in this envelope

bool geos::geom::prep::BasicPreparedGeometry::envelopesIntersect (  const geom::Geometry *  g  )  const [protected]

Determines whether a Geometry g interacts with this geometry by testing the geometry envelopes. Parameters: g  a Geometry Returns: true if the envelopes intersect

const geom::Geometry& geos::geom::prep::BasicPreparedGeometry::getGeometry (   )  const [inline, virtual]

Gets the original Geometry which has been prepared. Returns: the base geometry 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) Returns: a List of Coordinate

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. Parameters: geom  the test geometry repPts  the representative points of the target geometry Returns: true if any component intersects the areal test 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.
