Field Summary

static int	AO_BACK Axis is pointing BACK ( == -FRONT) e.g. the Axis through the intersection of the opposite of the Greenwich meridian and equator.
static int	AO_DOWN Axis is pointing DOWN ( == -UP)
static int	AO_EAST Axis is pointing EAST( == -WEST) the intersection of the equator with longitude 90°E.
static int	AO_FRONT Axis is pointing FRONT( == -BACK), e.g. the Axis through the intersection of the Greenwich meridian and equator.
static int	AO_NORTH Axis is pointing NORTH ( == -SOUTH) e.g Polar axis positive northwards.
static int	AO_OTHER Axis is pointing in an OTHER direction, which is not specified.
static int	AO_PERPENDICULAR Axis is pointing PERPENDICULAR to the earth's surface, which is used for a vertical axis.
static int	AO_SOUTH Axis is pointing SOUTH ( == -NORTH )
static int	AO_UP Axis is pointing UP ( == -DOWN ),
static int	AO_WEST Axis is pointing WEST( == -EAST)

Constructor Summary

Axis(IUnit units, String axisName, int orientation)

Axis(IUnit units, String axisName, String orientation)
Parses the given orientation and creates a valid orientation of it's non-case-sensitive version.

Axis(String name, int orientation)
An Axis with unit set to metre.

Axis(String name, String orientation)
Parses the given orientation and creates a valid orientation of it's non-case-sensitive version.

Method Summary

boolean	equals(Object otherAxis)
int	getOrientation()
String	getOrientationAsString()
IUnit	getUnits()
int	hashCode() Implementation as proposed by Joshua Block in Effective Java (Addison-Wesley 2001), which supplies an even distribution and is relatively fast.
String	toString()

Constructor Detail

Axis

public Axis(IUnit units,
            String axisName,
            int orientation)

Parameters:

units - of this axis

axisName - of this axis (e.g. longitude...)

orientation - of the positive scale direction, one of Axis.AO*. If an unknown value is supplied AO_OTHER is assumed.

Axis

public Axis(IUnit units,
            String axisName,
            String orientation)

Parses the given orientation and creates a valid orientation of it's non-case-sensitive version. If no conversion was found, AO_OTHER will be used.

Parameters:

units - of the axis.

axisName - of the axis.

orientation - of the axis as a string for example north

Axis

public Axis(String name,
            int orientation)

An Axis with unit set to metre.

Parameters:

name - of this axis (e.g. longitude...)

orientation - of the positive scale direction, one of Axis.AO*. If an unknown value is supplied AO_OTHER is assumed.

Axis

public Axis(String name,
            String orientation)

Parses the given orientation and creates a valid orientation of it's non-case-sensitive version. If no conversion was found, AO_OTHER will be used. This axis will have metres as it's unit.

Parameters:

name - of the axis

orientation - of the axis as a string for example north

Method Detail

getOrientation

public final int getOrientation()

Specified by:

getOrientation in interface IAxis

Returns:

the orientation.

getUnits

public final IUnit getUnits()

Specified by:

getUnits in interface IAxis

Returns:

the units.

toString

public String toString()

Overrides:

toString in class CRSIdentifiable

equals

public boolean equals(Object otherAxis)

Overrides:

equals in class CRSIdentifiable

hashCode

public int hashCode()

Implementation as proposed by Joshua Block in Effective Java (Addison-Wesley 2001), which supplies an even distribution and is relatively fast. It is created from field f as follows:

• boolean -- code = (f ? 0 : 1)
• byte, char, short, int -- code = (int)f
• long -- code = (int)(f ^ (f >>>32))
• float -- code = Float.floatToIntBits(f);
• double -- long l = Double.doubleToLongBits(f); code = (int)(l ^ (l >>> 32))
• all Objects, (where equals( ) calls equals( ) for this field) -- code = f.hashCode( )
• Array -- Apply above rules to each element

Combining the hash code(s) computed above: result = 37 * result + code;

Overrides:

hashCode in class CRSIdentifiable

Returns:

(int) ( result >>> 32 ) ^ (int) result;

See Also:

Object.hashCode()

getOrientationAsString

public String getOrientationAsString()

Specified by:

getOrientationAsString in interface IAxis

Returns:

an 'English' representation for the Axis Orientation, or Unknown if the given direction is not known.
