@Immutable
public class DefaultCartesianCS
extends DefaultAffineCS
implements CartesianCS

A 1-, 2-, or 3-dimensional coordinate system. Gives the position of points relative to orthogonal straight axes in the 2- and 3-dimensional cases. In the 1-dimensional case, it contains a single straight coordinate axis. In the multi-dimensional case, all axes shall have the same length unit of measure. A CartesianCS shall have one, two, or three axis.

Constructor Detail

DefaultCartesianCS

public DefaultCartesianCS(CartesianCS cs)

Constructs a new coordinate system with the same values than the specified one. This copy constructor provides a way to wrap an arbitrary implementation into a Geotk 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.

DefaultCartesianCS

public DefaultCartesianCS(String name,
                          CoordinateSystemAxis axis0,
                          CoordinateSystemAxis axis1)

Constructs a two-dimensional coordinate system from a name.

Parameters:

name - The coordinate system name.

axis0 - The first axis.

axis1 - The second axis.

DefaultCartesianCS

public DefaultCartesianCS(String name,
                          CoordinateSystemAxis axis0,
                          CoordinateSystemAxis axis1,
                          CoordinateSystemAxis axis2)

Constructs a three-dimensional coordinate system from a name.

Parameters:

name - The coordinate system name.

                          CoordinateSystemAxis axis1)

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

Parameters:

properties - Set of properties. Should contains at least "name".

axis0 - The first axis.

axis1 - The second axis.

axis2 - The third axis.

Method Detail

wrap

public static DefaultCartesianCS wrap(CartesianCS object)

Returns a Geotk 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 Geotk implementation, then the given object is returned unchanged. Otherwise a new Geotk implementation is created and initialized to the attribute values of the given object.

Parameters:

object - The object to wrap in a Geotk implementation, or null if none.

Returns:

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

distance

public Measure distance(double[] coord1,
                        double[] coord2)
                 throws UnsupportedOperationException,
                        MismatchedDimensionException

Computes the distance between two points.

Overrides:

distance in class AbstractCS

Parameters:

coord1 - Coordinates of the first point.

coord2 - Coordinates of the second point.

Returns:

The distance between coord1 and coord2.

Throws:

UnsupportedOperationException - if this coordinate system can't compute distances.

MismatchedDimensionException - if a coordinate doesn't have the expected dimension.

usingUnit

public DefaultCartesianCS usingUnit(Unit<?> unit)
                             throws IllegalArgumentException

Returns a new coordinate system with the same properties than the current one except for axis units.

Overrides:

usingUnit in class DefaultAffineCS

Parameters:

unit - The unit for the new axis.

Returns:

A coordinate system with axis using the specified units.

Throws:

IllegalArgumentException - If the specified unit is incompatible with the expected one.
