Constructor Detail

CurveBoundaryImpl

public CurveBoundaryImpl(CoordinateSystem crs,
                         Position sp,
                         Position ep)

constructor of curve_boundary with CS_CoordinateSystem and startpoint and endpoint

Method Detail

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.

getStartPoint

public Position getStartPoint()

returns the StartPoint of the boundary

Specified by:

getStartPoint in interface CurveBoundary

getEndPoint

public Position getEndPoint()

returns the EndPoint of the boundary

Specified by:

getEndPoint in interface CurveBoundary

equals

public boolean equals(Object other)

checks if this curve is completly equal to the submitted geometry

Overrides:

equals in class GeometryImpl

Parameters:

other - object to compare to

Returns:

true if the objects are equal, else false

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.

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

calculateParam

protected void calculateParam()

calculates the envelope of the curve boundary

Specified by:

calculateParam in class GeometryImpl

toString

public String toString()

Overrides:

toString in class GeometryImpl

Returns:
