Constructor Detail

DefaultPolarCS

public DefaultPolarCS(PolarCS 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 Geotools 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.

Since:
2.2

DefaultPolarCS

public DefaultPolarCS(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.

DefaultPolarCS

public DefaultPolarCS(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.
Method Detail

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.
