The coordinate reference system used in direct position coordinates.

Constructor Detail

Geometry

public Geometry(org.opengis.referencing.crs.CoordinateReferenceSystem crs)

Constructs a geometry with the specified coordinate reference system.

Parameters:

crs - The coordinate reference system used in direct position coordinates.

Method Detail

getCoordinateReferenceSystem

public org.opengis.referencing.crs.CoordinateReferenceSystem getCoordinateReferenceSystem()

Returns the coordinate reference system used in direct position coordinates.

Specified by:

getCoordinateReferenceSystem in interface org.opengis.spatialschema.geometry.Geometry

Returns:

The coordinate reference system used in direct position coordinates.

getCoordinateDimension()

getCoordinateDimension

public int getCoordinateDimension()

Returns the dimension of the coordinates that define this , which must be the same as the coordinate dimension of the coordinate reference system for this .

Specified by:

getCoordinateDimension in interface org.opengis.spatialschema.geometry.Geometry

Returns:

The coordinate dimension.

transform

public org.opengis.spatialschema.geometry.Geometry transform(org.opengis.referencing.crs.CoordinateReferenceSystem newCRS)
                                                      throws org.opengis.referencing.operation.TransformException

Returns a new that is the coordinate transformation of this into the passed coordinate reference system within the accuracy of the transformation.

Specified by:

transform in interface org.opengis.spatialschema.geometry.Geometry

Parameters:

newCRS - The new coordinate reference system.

Returns:

The transformed .

Throws:

org.opengis.referencing.operation.TransformException - if the transformation failed.

clone

public java.lang.Object clone()
                       throws java.lang.CloneNotSupportedException

Returns a clone of this geometry with deep copy semantic. Any change on this object will have no impact on the returned clone, and conversely. For big geometries, implementations are encouraged to share as much internal data as possible (as opposed to performing a real copy of the data), while preserving the deep copy semantic.

The default implementation throws CloneNotSupportedException. If subclasses implements Cloneable, then they should overrides this method.

Specified by:

clone in interface org.opengis.spatialschema.geometry.Geometry

Throws:

java.lang.CloneNotSupportedException - if this object do not support clone. This exception is never throws if this object implements Cloneable.
