Member Function Documentation

buffer()

static std::unique_ptr< 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

geom	the first Geometry
distance	the buffer distance

Returns

the Geometry representing the buffer of the input Geometry.

difference()

static std::unique_ptr< 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.

intersection()

static std::unique_ptr< 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.

symDifference()

static std::unique_ptr< 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.

Union()

static std::unique_ptr< 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.
