geom::Geometry* geos::precision::EnhancedPrecisionOp::buffer (  const geom::Geometry *  geom, double  distance )  [static]

Computes the buffer of a Geometry, using enhanced precision. This method should no longer be necessary, since the buffer algorithm now is highly robust. Parameters: geom0  the first Geometry distance  the buffer distance Returns: the Geometry representing the buffer of the input Geometry.

geom::Geometry* geos::precision::EnhancedPrecisionOp::difference (  const geom::Geometry *  geom0, const geom::Geometry *  geom1 )  [static]

Computes the set-theoretic difference of two Geometrys, using enhanced precision. Parameters: geom0  the first Geometry geom1  the second Geometry Returns: the Geometry representing the set-theoretic difference of the input Geometries.

geom::Geometry* geos::precision::EnhancedPrecisionOp::intersection (  const geom::Geometry *  geom0, const geom::Geometry *  geom1 )  [static]

Computes the set-theoretic intersection of two Geometrys, using enhanced precision. Parameters: geom0  the first Geometry geom1  the second Geometry Returns: the Geometry representing the set-theoretic intersection of the input Geometries.

geom::Geometry* geos::precision::EnhancedPrecisionOp::symDifference (  const geom::Geometry *  geom0, const geom::Geometry *  geom1 )  [static]

Computes the set-theoretic symmetric difference of two Geometrys, using enhanced precision. Parameters: geom0  the first Geometry geom1  the second Geometry Returns: the Geometry representing the set-theoretic symmetric difference of the input Geometries.

geom::Geometry* geos::precision::EnhancedPrecisionOp::Union (  const geom::Geometry *  geom0, const geom::Geometry *  geom1 )  [static]

Computes the set-theoretic union of two Geometrys, using enhanced precision. Parameters: geom0  the first Geometry geom1  the second Geometry Returns: the Geometry representing the set-theoretic union of the input Geometries.
