@UML(identifier="CS_AxisDirection", specification=ISO_19111) public final class AxisDirection extends CodeList<AxisDirection>
The direction of positive increments in the coordinate value for a coordinate system axis. This direction is exact in some cases, and is approximate in other cases.Some coordinate systems use non-standard orientations. For example, the first axis in South African grids usually points West, instead of East. This information is obviously relevant for algorithms converting South African grid coordinates into Lat/Long.

values
public static AxisDirection[] values()
Returns the list ofAxisDirection
s.- Returns:

family
public AxisDirection[] family()
Returns the list of enumerations of the same kind than this enum.- Specified by:
family
in classCodeList<AxisDirection>
- Returns:
- The codes of the same kind than this code.
-
opposite
public AxisDirection opposite()
Returns the opposite direction of this axis. The opposite direction of North is South, and the opposite direction of South is North. The same applies to East-West, Up-Down and Future-Past, etc. If this axis direction has no opposite, then this method returnsnull
.- Returns:
- The opposite direction, or
null
if none or unknown.
-
absolute
public AxisDirection absolute()
Returns the "absolute" direction of this axis. This "absolute" operation is similar to theMath.abs(int)
method in that "negative" directions like (SOUTH
,WEST
,DOWN
,PAST
) are changed for their "positive" counterparts (NORTH
,EAST
,UP
,FUTURE
). More specifically, the following conversion table is applied:
Direction Absolute value NORTH

valueOf
public static AxisDirection valueOf(String code)
Returns the axis direction that matches the given string, or returns a new one if none match it.- Parameters:
code
- The name of the code to fetch or to create.- Returns:
