Constructor Detail

DefaultAffineCS

public DefaultAffineCS(AffineCS 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.

2.2

DefaultAffineCS

public DefaultAffineCS(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.

DefaultAffineCS

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

Constructs a three-dimensional coordinate system from a name.

Parameters:

name - The coordinate system name.

axis0 - The first axis.

axis1 - The second axis.

axis2 - The third axis.

DefaultAffineCS

public DefaultAffineCS(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.

Parameters:

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

axis0 - The first axis.

axis1 - The second axis.

DefaultAffineCS

public DefaultAffineCS(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 superclass 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 DefaultAffineCS wrap(AffineCS 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.

This method checks for the CartesianCS sub-interface. If that interface is found, then this method delegates to the corresponding wrap static method.

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.

3.18

isCompatibleDirection

protected boolean isCompatibleDirection(AxisDirection direction)

Returns true if the specified axis direction is allowed for this coordinate system. The default implementation accepts all directions except temporal ones (i.e. FUTURE and PAST).

Overrides:

isCompatibleDirection in class AbstractCS

Parameters:

direction - The direction to test for compatibility.

Returns:

true if the given direction is compatible with this coordinate system.

isCompatibleUnit

protected boolean isCompatibleUnit(AxisDirection direction,
                                   Unit<?> unit)

Returns true if the specified unit is compatible with metres. In addition, this method also accepts Unit.ONE, which is used for coordinates in a grid. This method is invoked at construction time for checking units compatibility.

Overrides:

isCompatibleUnit in class AbstractCS

Parameters:

direction - The direction of the axis having the given unit.

unit - The unit to test for compatibility.

Returns:

true if the given unit is compatible with this coordinate system.

Since:

2.2

usingUnit

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

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

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.
