0028 //! Root class to define a boundary which will form part of a
0029 //! contour around a gap requiring filling.
0030 //! Any new type of constrained boundary must inherit this class.
0031 //! The GeomFill package provides two classes to define constrained boundaries:
0032 //! -   GeomFill_SimpleBound to define an unattached boundary
0033 //! -   GeomFill_BoundWithSurf to define a boundary attached to a surface.
0034 //! These objects are used to define the boundaries for a
0035 //! GeomFill_ConstrainedFilling framework.
