constructor

Method Detail

getExteriorRing

public GM_Ring getExteriorRing()

gets the exterior ring

Specified by:

getExteriorRing in interface GM_SurfaceBoundary

getInteriorRings

public GM_Ring[] getInteriorRings()

gets the interior ring(s)

Specified by:

getInteriorRings in interface GM_SurfaceBoundary

getBoundary

public GM_Boundary getBoundary()

returns the boundary of the boundary

Specified by:

getBoundary in interface GM_Object

Overrides:

getBoundary in class GM_Object_Impl

equals

public boolean equals(java.lang.Object other)

checks if this curve is completly equal to the submitted geometry

Overrides:

equals in class GM_Object_Impl

Parameters:

other - object to compare to

Returns:

true if the objects are equal, else false

getDimension

public int getDimension()

The operation "dimension" shall return the inherent dimension of this GM_Object, 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 GM_Object

getCoordinateDimension

public int getCoordinateDimension()

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

Specified by:

getCoordinateDimension in interface GM_Object

clone

public java.lang.Object clone()

returns a copy of the geometry

Overrides:

clone in class GM_Object_Impl

intersects

public boolean intersects(GM_Object gmo)

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

Specified by:

intersects in interface GM_Object

Overrides:

intersects in class GM_Object_Impl

Parameters:

gmo - the GM_Object to intersect with

Returns:

true if the objects intersects, else false

contains

public boolean contains(GM_Object gmo)

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

At the moment the operation just works with point geometries

Specified by:

contains in interface GM_Object

Overrides:

contains in class GM_Object_Impl

Parameters:

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

Returns:

true if the given object is contained, else false

contains

public boolean contains(GM_Position position)

The Boolean valued operation "contains" shall return TRUE if this GM_Object contains a single point given by a coordinate.

dummy implementation

Specified by:

contains in interface GM_Object

Overrides:

contains in class GM_Object_Impl

Parameters:

position - GM_Position to test (whether is is contained)

Returns:

true if the given object is contained, else false

calculateEnvelope

private void calculateEnvelope()

calculates the envelope of the surface boundary

calculateCentroid

private void calculateCentroid()

calculates the centroid of the surface boundary

calculateParam

protected void calculateParam()

calculates the centroid and the envelope of the surface boundary

Specified by:

calculateParam in class GM_Object_Impl

toString

public java.lang.String toString()

Overrides:

toString in class GM_Object_Impl

Returns:

isCycle

public boolean isCycle()

A geometric object, which has no boundary is a cycle.

Specified by:

isCycle in interface GM_Boundary
