Class CommonBitsOp

Hierarchy: Object , CommonBitsOp

public class CommonBitsOp

Provides versions of Geometry spatial functions which use common bit removal to reduce the likelihood of robustness problems.

In the current implementation no rounding is performed on the reshifted result geometry, which means that it is possible that the returned Geometry is invalid. Client classes should check the validity of the returned result themselves.

version: 1.7

public CommonBitsOp()

Creates a new instance of class, which reshifts result Geometrys.

public CommonBitsOp(boolean returnToOriginalPrecision)

Creates a new instance of class, specifying whether the result Geometrys should be reshifted.

Parameters:: returnToOriginalPrecision - returnToOriginalPrecision

public 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 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 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, to be subtracted from the first

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

public Geometry symDifference(Geometry geom0, Geometry geom1)

Computes the set-theoretic symmetric difference of two geometries, 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 Geometry buffer(Geometry geom0, double distance)

Computes the buffer a geometry, using enhanced precision.

Parameters:: geom0 - geom0 the Geometry to buffer; distance - distance the buffer distance

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