Parameters:

crs - spatial reference system of the point

PointImpl

public PointImpl(double x,
                 double y,
                 CoordinateSystem crs)

constructor for initializing a point within a two-dimensional coordinate system

Parameters:

x - x-value of the point

y - y-value of the point

crs - spatial reference system of the point

PointImpl

public PointImpl(double x,
                 double y,
                 double z,
                 CoordinateSystem crs)

constructor for initializing a point within a three-dimensional coordinate system

Parameters:

y - y-value of the point

z - z-value of the point

crs - spatial reference system of the point

PointImpl

public PointImpl(Point gmo)

constructor

Parameters:

PointImpl

public PointImpl(Position gmo,
                 CoordinateSystem crs)

constructor

Parameters:

gmo - existing GM_Point

crs - spatial reference system of the point

Method Detail

equals

public boolean equals(Object other)

checks if this point is completly 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()

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

getCoordinateDimension

public int getCoordinateDimension()

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

clone

public Object clone()

returns a shallow copy of the geometry.

Overrides:

clone in class GeometryImpl

Returns:

a shallow copy of the geometry. this isn't realized at this level so a CloneNotSupportedException will be thrown.

getX

public double getX()

returns the x-value of this point

Specified by:

getX in interface Point

getY

public double getY()

returns the y-value of this point

Specified by:

getY in interface Point

getZ

public double getZ()

returns the y-value of this point

Specified by:

getZ in interface Point

getAsArray

public double[] getAsArray()

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.

Specified by:

getAsArray in interface Point

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

getPosition

public Position getPosition()

Description copied from interface: Point

returns the position of the point

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

Returns:

the String representation containing the crs, empty-field and the mut-field
