Examples of org.opengis.referencing.cs.AxisDirection.absolute()

org.opengis.referencing.cs.AxisDirection.absolute()

Returns the "absolute" direction of this axis. This "absolute" operation is similar to the {@code Math.abs(int)}method in that "negative" directions like ( {@link #SOUTH}, {@link #WEST}, {@link #DOWN}, {@link #PAST}) are changed for their "positive" counterparts ( {@link #NORTH}, {@link #EAST}, {@link #UP}, {@link #FUTURE}). More specifically, the following conversion table is applied:

Direction	Absolute value
{@link #NORTH}	{@link #NORTH}
{@link #SOUTH}	{@link #NORTH}
{@link #EAST}	{@link #EAST}
{@link #WEST}	{@link #EAST}
{@link #UP}	{@link #UP}
{@link #DOWN}	{@link #UP}

Direction	Absolute value
{@link #DISPLAY_RIGHT}	{@link #DISPLAY_RIGHT}
{@link #DISPLAY_LEFT}	{@link #DISPLAY_RIGHT}
{@link #DISPLAY_UP}	{@link #DISPLAY_UP}
{@link #DISPLAY_DOWN}	{@link #DISPLAY_UP}
{@link #FUTURE}	{@link #FUTURE}
{@link #PAST}	{@link #FUTURE}

{@link #OTHER}

@return The direction from the above table.

            // Not the expected pattern.
            return null;
        }
        String group = m.group(1);
        final AxisDirection baseDirection = findDirection(BASE_DIRECTIONS, group);
        if (baseDirection == null || !AxisDirection.NORTH.equals(baseDirection.absolute())) {
            // We expected "North" or "South" direction.
            return null;
        }
        group = m.group(2);
        double meridian;

            boolean hasFound = false;
            final AxisDirection dstAxe = dstAxis[dstIndex];
            final AxisDirection search = dstAxe.absolute();
            for (int srcIndex=0; srcIndex<srcAxis.length; srcIndex++) {
                final AxisDirection srcAxe = srcAxis[srcIndex];
                if (search.equals(srcAxe.absolute())) {
                    if (hasFound) {
                        // TODO: Use the localized version of 'getName' in GeoAPI 2.1
                        throw new IllegalArgumentException(Errors.format(ErrorKeys.COLINEAR_AXIS_$2,
                                                           srcAxe.name(), dstAxe.name()));
                    }
