template<int dim, int subdim>
class regina::detail::SimplexFaces< dim, subdim >
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.
◆ clear()
template<int dim, int subdim>
Resets all face pointers to null.
The faces themselves are not destroyed, and the mapping permutations are not touched.
◆ sameDegrees()
template<int dim, int subdim>
Tests whether the subdim-face degrees of this and the given simplex are identical, under the given relabelling.
- Parameters
-
other | the simplex to compare against this. |
p | a mapping from the vertices of this simplex to the vertices of other. |
- Returns
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.
◆ face_
template<int dim, int subdim>
The faces of the underlying triangulation that form the individual subdim-faces of this simplex.
◆ mapping_
template<int dim, int subdim>
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().
