                    CoordinateSystem crs)

constructor

Parameters:

position - existing position

crs - spatial reference system of the point

Method Detail

equals

public boolean equals(Object other)

checks if this point is completely equal to the submitted geometry

Overrides:

equals in class GeometryImpl

Parameters:

other - the Geometry to test for equality

Returns:

true if the objects are equal, else false

getDimension

public int getDimension()

Description copied from interface: Geometry

The operation "dimension" shall return the inherent dimension of this Geometry, which shall be less than or equal to the coordinate dimension. The dimension of a collection of geometric objects shall be the largest dimension of any of its pieces. Points are 0-dimensional, curves are 1-dimensional, surfaces are 2-dimensional, and solids are 3-dimensional.

Specified by:

getDimension in interface Geometry

Returns:

0

getCoordinateDimension

public int getCoordinateDimension()

Description copied from interface: Geometry

The operation "coordinateDimension" shall return the dimension of the coordinates that define this Geometry, which must be the same as the coordinate dimension of the coordinate reference system for this Geometry.

Specified by:

getCoordinateDimension in interface Geometry

Returns:

the number of ordinates contained in this point.

clone

public Object clone()

Overrides:

clone in class GeometryImpl

getX

public double getX()

Specified by:

getX in interface Point

Returns:

the x-value of the point

getY

public double getY()

Specified by:

getY in interface Point

Returns:

the y-value of the point

getZ

public double getZ()

Specified by:

getZ in interface Point

Returns:

the z-value of the point of Double.NaN if the dimension != 3

getAsArray

public double[] getAsArray()

Specified by:

getAsArray in interface Point

Returns:

the x- and y-value of the point as a two dimensional array the first field contains the x- the second field the y-value.

translate

public void translate(double[] d)

translate the point by the submitted values. the dz- value will be ignored.

Specified by:

translate in interface Geometry

Overrides:

translate in class GeometryImpl

Parameters:

d - vector to translate the geometry with

getPosition

public Position getPosition()

Specified by:

getPosition in interface Point

Returns:

position

intersects

public boolean intersects(Geometry gmo)

The Boolean valued operation "intersects" shall return TRUE if this Geometry intersects another Geometry. Within a Complex, the Primitives do not intersect one another. In general, topologically structured data uses shared geometric objects to capture intersection information.

dummy implementation

Specified by:

intersects in interface Geometry

Overrides:

intersects in class GeometryImpl

Parameters:

gmo - the Geometry to intersect with

Returns:

true if the objects intersects, else false

contains

public boolean contains(Geometry gmo)

The Boolean valued operation "contains" shall return TRUE if this Geometry contains another Geometry.

Specified by:

contains in interface Geometry

Overrides:

contains in class GeometryImpl

Parameters:

gmo - the Geometry to test (whether is is contained)

Returns:

true if the given object is contained, else false

calculateParam

protected void calculateParam()

recalculates internal parameters

Specified by:

calculateParam in class GeometryImpl

toString

public String toString()

Overrides:

toString in class GeometryImpl
