MutableFaceGraph Concept Reference
Concepts

## Definition

The concept `MutableFaceGraph` refines the concepts `FaceGraph` and `MutableHalfedgeGraph` and adds the requirement for operations to add faces and to modify face-halfedge relations.

Refines:

  `FaceGraph`

  `MutableHalfedgeGraph`

Has Models:

  `CGAL::Polyhedron_3`

  `CGAL::Surface_mesh`

Notations

`G`
  A type that is a model of `MutableFaceGraph`.
`g`
  An object of type `G`.
`h`
  A halfedge descriptor.
`f`
  A face descriptor.

Valid Expressions

Expression | returns | Description
--- | --- | ---
`add_face(g)` | `face_descriptor` | Adds a new face to the graph without initializing the connectivity.
`remove_face(f, g)` | `void` | Removes `f` from the graph.
`set_face(h, f, g)` | `void` | Sets the corresponding face of `h` to `f`.
`set_halfedge(f, h, g)` | `void` | Sets the corresponding halfedge of `f` to `h`.
