static 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.
static 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.
static 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.
static 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.
static 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.
