Interface OrientableCurve

All Superinterfaces:

Geometry, OrientablePrimitive, Primitive, TransfiniteSet

All Known Subinterfaces:

CompositeCurve, Curve, Ring

public interface OrientableCurve

extends OrientablePrimitive

A curve and an orientation inherited from OrientablePrimitive. If the orientation is positive, then the OrientableCurve is a curve. If the orientation is negative, then the OrientableCurve is related to another curve with a parameterization that reverses the sense of the curve traversal.

Method Detail

getBoundary

CurveBoundary getBoundary()

Returns an ordered pair of points, which are the start point and end point of the curve. If the curve is closed, then the boundary shall be empty.

Specified by:

getBoundary in interface Primitive

Returns:

The sets of positions on the boundary.

UML identifier (operation): boundary

getComposite

CompositeCurve getComposite()

Returns the owner of this orientable curve, or null if none.

Returns:

The owner of this orientable curve, or null if none.
