public class PreparedGeometryCollection
extends AbstractGeometryCollection

A base class for PreparedGeometry subclasses. Contains default implementations for methods, which simply delegate to the equivalent Geometry methods. This class may be used as a "no-op" class for Geometry types which do not have a corresponding PreparedGeometry implementation.

Method Detail

getBoundingBox

public BoundingBox getBoundingBox()

Description copied from class: AbstractGeometry

Gets an BoundingBoxDoubleGf containing the minimum and maximum x and y values in this Geometry. If the geometry is empty, an empty BoundingBoxDoubleGf is returned.

The returned object is a copy of the one maintained internally, to avoid aliasing issues. For best performance, clients which access this boundingBox frequently should cache the return value.

Specified by:

getBoundingBox in interface Geometry

Overrides:

getBoundingBox in class AbstractGeometry

Returns:

the boundingBox of this Geometry.

getGeometries

public <V extends Geometry> List<V> getGeometries()

Specified by:

getGeometries in interface Geometry

Overrides:

getGeometries in class AbstractGeometry

getGeometry

public <V extends Geometry> V getGeometry(int partIndex)

Description copied from class: AbstractGeometry

Returns an element Geometry from a GeometryCollection (or this, if the geometry is not a collection).

Specified by:

getGeometry in interface Geometry

Overrides:

getGeometry in class AbstractGeometry

Parameters:

partIndex - the index of the geometry element

Returns:

the n'th geometry contained in this geometry

getGeometryCount

public int getGeometryCount()

Description copied from class: AbstractGeometry

Returns the number of Geometrys in a GeometryCollection (or 1, if the geometry is not a collection).

Specified by:

getGeometryCount in interface Geometry

Overrides:

getGeometryCount in class AbstractGeometry

Returns:

the number of geometries contained in this geometry

getGeometryFactory

public GeometryFactory getGeometryFactory()

Description copied from interface: Geometry

Gets the geometryFactory which contains the context in which this geometry was created.

Specified by:

getGeometryFactory in interface Geometry

Overrides:

getGeometryFactory in class AbstractGeometry

Returns:

the geometryFactory for this geometry

getRepresentativePoints

public List<Point> getRepresentativePoints()

Gets the list of representative points for this geometry. One vertex is included for every component of the geometry (i.e. including one for every ring of polygonal geometries). Do not modify the returned list!

Returns:

a List of Coordinate

moveVertex

public <V extends Geometry> V moveVertex(Point newPoint,
                                int... vertexId)

Specified by:

moveVertex in interface Geometry

Overrides:

moveVertex in class AbstractGeometryCollection

prepare

public Geometry prepare()
