constructor

Method Detail

getExteriorRing

public Ring getExteriorRing()

gets the exterior ring

Specified by:

getExteriorRing in interface SurfaceBoundary

getInteriorRings

public Ring[] getInteriorRings()

gets the interior ring(s)

Specified by:

getInteriorRings in interface SurfaceBoundary

getBoundary

public Boundary getBoundary()

returns the boundary of the boundary

Specified by:

getBoundary in interface Geometry

Overrides:

getBoundary in class GeometryImpl

equals

public boolean equals(Object other)

checks if this curve is completly equal to the submitted geometry

Overrides:

equals in class GeometryImpl

Parameters:

other - object to compare to

Returns:

true if the objects are equal, else false

getDimension

public int getDimension()

The operation "dimension" shall return the inherent dimension of this Geometry, which shall be less than or equal to the coordinate dimension. The dimension of a collection of geometric objects shall be the largest dimension of any of its pieces. Points are 0-dimensional, curves are 1-dimensional, surfaces are 2-dimensional, and solids are 3-dimensional.

Specified by:

getDimension in interface Geometry

getCoordinateDimension

public int getCoordinateDimension()

The operation "coordinateDimension" shall return the dimension of the coordinates that define this Geometry, which must be the same as the coordinate dimension of the coordinate reference system for this Geometry.

Specified by:

getCoordinateDimension in interface Geometry

clone

public Object clone()

returns a copy of the geometry

Overrides:

clone in class GeometryImpl

Returns:

a shallow copy of the geometry. this isn't realized at this level so a CloneNotSupportedException will be thrown.

intersects

public boolean intersects(Geometry gmo)

The Boolean valued operation "intersects" shall return TRUE if this Geometry intersects another Geometry. Within a Complex, the Primitives do not intersect one another. In general, topologically structured data uses shared geometric objects to capture intersection information.

Specified by:

intersects in interface Geometry

Overrides:

intersects in class GeometryImpl

Parameters:

gmo - the Geometry to intersect with

Returns:

true if the objects intersects, else false

contains

public boolean contains(Geometry gmo)

The Boolean valued operation "contains" shall return TRUE if this Geometry contains another Geometry.

At the moment the operation just works with point geometries

Specified by:

contains in interface Geometry

Overrides:

contains in class GeometryImpl

Parameters:

gmo - the Geometry to test (whether is is contained)

Returns:

true if the given object is contained, else false

contains

public boolean contains(Position position)

The Boolean valued operation "contains" shall return TRUE if this Geometry contains a single point given by a coordinate.

dummy implementation

Specified by:

contains in interface Geometry

Overrides:

contains in class GeometryImpl

Parameters:

position - Position to test (whether is is contained)

Returns:

true if the given object is contained, else false

calculateParam

protected void calculateParam()

calculates the centroid and the envelope of the surface boundary

Specified by:

calculateParam in class GeometryImpl

toString

public String toString()

Overrides:

toString in class GeometryImpl

Returns:
