## Definition

template<typename Traits, typename Fb>
class CGAL::Constrained_triangulation_face_base_2< Traits, Fb >

The class `Constrained_triangulation_face_base_2` is the default model for the concept `ConstrainedTriangulationFaceBase_2` to be used as base face class of constrained triangulations.

Is model of
  `ConstrainedTriangulationFaceBase_2`

Template Parameters

  Traits | must be a geometric traits.
  Fb | must be a model of the concept `TriangulationFaceBase_2`. Its default is `Triangulation_face_base_2<Traits>`

The class `Constrained_triangulation_face_base_2` derives from `Fb` and adds three Boolean to deal with information about constrained edges.

The member functions `cw(int i)`, `ccw(int i)` and `reorient` are overloaded to update information about constrained edges.
