30//! The abstract class BoundedCurve describes the
31//! common behavior of bounded curves in 2D space. A
32//! bounded curve is limited by two finite values of the
33//! parameter, termed respectively "first parameter" and
34//! "last parameter". The "first parameter" gives the "start
35//! point" of the bounded curve, and the "last parameter"
36//! gives the "end point" of the bounded curve.
37//! The length of a bounded curve is finite.
38//! The Geom2d package provides three concrete
39//! classes of bounded curves:
40//! - two frequently used mathematical formulations of complex curves:
41//! - Geom2d_BezierCurve,
42//! - Geom2d_BSplineCurve, and
43//! - Geom2d_TrimmedCurve to trim a curve, i.e. to
44//! only take part of the curve limited by two values of
45//! the parameter of the basis curve.
