version: 1.7

public static Geometry intersection(Geometry geom0, Geometry geom1)

Computes the set-theoretic intersection of two Geometrys, using enhanced precision.

Parameters:: geom0 - geom0 the first Geometry; geom1 - geom1 the second Geometry

Returns:: the Geometry representing the set-theoretic intersection of the input Geometries.

public static Geometry union(Geometry geom0, Geometry geom1)

Computes the set-theoretic union of two Geometrys, using enhanced precision.

Parameters:: geom0 - geom0 the first Geometry; geom1 - geom1 the second Geometry

Returns:: the Geometry representing the set-theoretic union of the input Geometries.

public static Geometry difference(Geometry geom0, Geometry geom1)

Computes the set-theoretic difference of two Geometrys, using enhanced precision.

Parameters:: geom0 - geom0 the first Geometry; geom1 - geom1 the second Geometry

Returns:: the Geometry representing the set-theoretic difference of the input Geometries.

public static Geometry symDifference(Geometry geom0, Geometry geom1)

Computes the set-theoretic symmetric difference of two Geometrys, using enhanced precision.

Parameters:: geom0 - geom0 the first Geometry; geom1 - geom1 the second Geometry

Returns:: the Geometry representing the set-theoretic symmetric difference of the input Geometries.

public static Geometry buffer(Geometry geom, double distance)

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 - geom the first Geometry; distance - distance the buffer distance

Returns:: the Geometry representing the buffer of the input Geometry.
