For each subdim-face of this simplex, maps vertices (0,1,...,subdim) of the underlying subdim-face of the triangulation to the corresponding vertices of this simplex, as described by faceMapping(). More... | |
Helper class for storing which subdim-faces of a dim-dimensional triangulation appear within each top-dimensional simplex.
This class is strongly related to FaceEmbedding<dim, subdim>. Whereas each FaceEmbedding object identifies some simplex in which a given subdim-face appears, each SimplexFaces object identifies all subdim-faces which appear within a given simplex.

Resets all face pointers to null.
The faces themselves are not destroyed, and the mapping permutations are not touched.

true
if and only if, for every i, subdim-face number i of this simplex has the same degree as its image in other under the relabelling p.
