getBoundary

public Pair<Point,Point> getBoundary()

Description copied from interface: Curve

The boundary of a curve is the set of points at either end of the curve. If the curve is a cycle, the two ends are identical, and the curve (if topologically closed) is considered to not have a boundary.

Specified by:

getBoundary in interface Curve

Returns:

boundary of a curve. If a curve does not have a boundary because it is closed an empty List shall be retruned

getCurveSegments

Returns the segments that constitute this curve.

Specified by:

getCurveSegments in interface Curve

Returns:

the segments that constitute this curve

getStartPoint

getLength

public Measure getLength(Unit requestedUnit)

Specified by:

getLength in interface Curve

Returns:

length of the curve

isClosed

public boolean isClosed()

Description copied from interface: Curve

Returns whether the curve forms a closed loop.

Specified by:

isClosed in interface Curve

Returns:

true, if the curve forms a closed loop, false otherwise

getCoordinateDimension

public int getCoordinateDimension()

Description copied from interface: Geometry

Returns the coordinate dimension, i.e. the dimension of the space that the geometry is embedded in.
