Field Detail

CRS

public static final VerticalCRS<Height> CRS

Holds the coordinate reference system for all instances of this class.

Method Detail

valueOf

public static Height valueOf(double value,
                             Unit<Length> unit)

Returns the vertical position corresponding to the specified coordinates.

Parameters:

value - the height above the WGS84 ellipsoid stated in the specified unit.

unit - the length unit in which the height is stated.

Returns:

the corresponding vertical position.

getCoordinateReferenceSystem

public VerticalCRS<?> getCoordinateReferenceSystem()

Description copied from class: Coordinates

Returns the reference system for this coordinates.

Specified by:

getCoordinateReferenceSystem in interface org.opengis.spatialschema.geometry.DirectPosition

Specified by:

getCoordinateReferenceSystem in class Coordinates<VerticalCRS<?>>

Returns:

the associated coordinate reference system.

getDimension

public int getDimension()

Description copied from class: Coordinates

OpenGIS® - The length of coordinate sequence (the number of entries). This is determined by the coordinate reference system.

Specified by:

getDimension in interface org.opengis.spatialschema.geometry.DirectPosition

Specified by:

getDimension in class Coordinates<VerticalCRS<?>>

Returns:

the dimensionality of this position.

getOrdinate

public double getOrdinate(int dimension)
                   throws IndexOutOfBoundsException

Description copied from class: Coordinates

OpenGIS® - Returns the ordinate at the specified dimension.

Specified by:

getOrdinate in interface org.opengis.spatialschema.geometry.DirectPosition

Specified by:

getOrdinate in class Coordinates<VerticalCRS<?>>

Parameters:

dimension - The dimension in the range 0 to dimension-1.

Returns:

The coordinate at the specified dimension.

Throws:

IndexOutOfBoundsException - if the specified dimension is out of bounds.

doubleValue

public final double doubleValue(Unit<Length> unit)

Description copied from interface: Measurable

Returns the value of this measurable stated in the specified unit as a double. If the measurable has too great a magnitude to be represented as a double, it will be converted to Double.NEGATIVE_INFINITY or Double.POSITIVE_INFINITY as appropriate.

Specified by:

doubleValue in interface Measurable<Length>

Parameters:

unit - the unit in which this measurable value is stated.

Returns:

the numeric value after conversion to type double.

longValue

public final long longValue(Unit<Length> unit)

Description copied from interface: Measurable

Returns the estimated integral value of this measurable stated in the specified unit as a long.

Note: This method differs from the Number.longValue() in the sense that the closest integer value is returned and an ArithmeticException is raised instead of a bit truncation in case of overflow (safety critical).

Specified by:

longValue in interface Measurable<Length>

Parameters:

unit - the unit in which the measurable value is stated.

Returns:

the numeric value after conversion to type long.

compareTo

public int compareTo(Measurable<Length> arg0)

Specified by:

compareTo in interface Comparable<Measurable<Length>>

copy

public Height copy()

Description copied from class: Coordinates

Returns a copy of these coordinates allocated by the calling thread (possibly on the stack).

Specified by:

copy in interface javolution.lang.ValueType

Specified by:

copy in class Coordinates<VerticalCRS<?>>

Returns:

an identical and independant copy of these coordinates .
