public class DefaultCartesianCS
extends DefaultAffineCS
implements CartesianCS

A 2- or 3-dimensional Cartesian coordinate system made of straight orthogonal axes. All axes shall have the same linear unit of measure.

Permitted associations

Projected	“Easting” or “Westing”, “Northing” or “Southing”

Immutability and thread safety

This class is immutable and thus thread-safe if the property values (not necessarily the map itself) and the Coordinate­System­Axis instances given to the constructor are also immutable. Unless otherwise noted in the javadoc, this condition holds if all components were created using only SIS factories and static constants.

Since:

0.4

Constructor Details

DefaultCartesianCS

public DefaultCartesianCS(Map<String,?> properties,
 CoordinateSystemAxis axis0,
 CoordinateSystemAxis axis1)

Constructs a two-dimensional coordinate system from a set of properties. The properties map is given unchanged to the super-class constructor. The following table is a reminder of main (not all) properties:

Recognized properties (non exhaustive list)

Property name	Value type	Returned by
"name"	ReferenceIdentifier or String	AbstractIdentifiedObject.getName()
"alias"	GenericName or Char­Sequence (optionally as array)	AbstractIdentifiedObject.getAlias()
"identifiers"	ReferenceIdentifier (optionally as array)	AbstractIdentifiedObject.getIdentifiers()
"remarks"	InternationalString or String	AbstractIdentifiedObject.getRemarks()

Parameters:

properties - the properties to be given to the identified object.

axis0 - the first axis (e.g. “Easting”).

axis1 - the second axis (e.g. “Northing”).

• Geodetic­Object­Factory.create­Cartesian­CS(Map, Coordinate­System­Axis, Coordinate­System­Axis)

DefaultCartesianCS

public DefaultCartesianCS(Map<String,?> properties,
 CoordinateSystemAxis axis0,
 CoordinateSystemAxis axis1,
 CoordinateSystemAxis axis2)

Constructs a three-dimensional coordinate system from a set of properties. The properties map is given unchanged to the super-class constructor.

Parameters:

properties - the properties to be given to the identified object.

axis0 - the first axis (e.g. “Geocentric X”).

axis1 - the second axis (e.g. “Geocentric Y”).

axis2 - the third axis (e.g. “Geocentric Z”).

• Geodetic­Object­Factory.create­Cartesian­CS(Map, Coordinate­System­Axis, Coordinate­System­Axis, Coordinate­System­Axis)

DefaultCartesianCS

protected DefaultCartesianCS(CartesianCS cs)

Creates a new coordinate system with the same values than the specified one. This copy constructor provides a way to convert an arbitrary implementation into a SIS one or a user-defined one (as a subclass), usually in order to leverage some implementation-specific API.

This constructor performs a shallow copy, i.e. the properties are not cloned.

Parameters:

cs - the coordinate system to copy.

See Also:

• cast­Or­Copy(Cartesian­CS)

Method Details

castOrCopy

public static DefaultCartesianCS castOrCopy(CartesianCS object)

Returns a SIS coordinate system implementation with the same values than the given arbitrary implementation. If the given object is null, then this method returns null. Otherwise if the given object is already a SIS implementation, then the given object is returned unchanged. Otherwise a new SIS implementation is created and initialized to the attribute values of the given object.

Parameters:

object - the object to get as a SIS implementation, or null if none.

Returns:

a SIS implementation containing the values of the given object (may be the given object itself), or null if the argument was null.

getInterface

public Class<? extends CartesianCS> getInterface()

Returns the GeoAPI interface implemented by this class. The SIS implementation returns Cartesian­CS.class.

Note for implementers

Subclasses usually do not need to override this method since GeoAPI does not define Cartesian­CS sub-interface. Overriding possibility is left mostly for implementers who wish to extend GeoAPI with their own set of interfaces.

Overrides:

get­Interface in class Default­Affine­CS

Returns:

Cartesian­CS.class or a user-defined sub-interface.

forConvention

public DefaultCartesianCS forConvention(AxesConvention convention)

Returns a coordinate system equivalent to this one but with axes rearranged according the given convention. If this coordinate system is already compatible with the given convention, then this method returns this.

Overrides:

for­Convention in class Default­Affine­CS

Parameters:

convention - the axes convention for which a coordinate system is desired.

Returns:

a coordinate system compatible with the given convention (may be this).
