Constructor Detail

GM_CurveBoundary_Impl

public GM_CurveBoundary_Impl(CS_CoordinateSystem crs,
                             GM_Position sp,
                             GM_Position ep)
                      throws GM_Exception

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 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 shallow copy of the geometry

Overrides:

clone in class GM_Object_Impl

getStartPoint

public GM_Position getStartPoint()

returns the StartPoint of the boundary

Specified by:

getStartPoint in interface GM_CurveBoundary

getEndPoint

public GM_Position getEndPoint()

returns the EndPoint of the boundary

Specified by:

getEndPoint in interface GM_CurveBoundary

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

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

intersectsMultiPrimitive

private boolean intersectsMultiPrimitive(GM_MultiPrimitive mprim)
                                  throws java.lang.Exception

the operations returns true if the submitted multi primitive intersects with the curve segment

Throws:

java.lang.Exception

calculateEnvelope

private void calculateEnvelope()

calculates the envelope of the curve boundary

calculateParam

protected void calculateParam()

calculates the envelope of the curve 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
