FaceEmbeddingBase () | |
Default constructor. More... | |
FaceEmbeddingBase (Simplex< dim > *simplex, int face) | |
Creates a new object containing the given data. More... | |

Simplex< dim > * | simplex () const |
Returns the top-dimensional simplex in which the underlying subdim-face of the triangulation is contained. More... | |
int | face () const |
Returns the corresponding face number of simplex(). More... | |
Perm< dim+1 > | vertices () const |

A default implementation for detailed output. More... | |
std::string | str () const |
Returns a short text representation of this object. More... | |
std::string | utf8 () const |

std::string | detail () const |
Returns a detailed text representation of this object. More... | |
Helper class that provides core functionality for describing how a subdim-face of a dim-dimensional triangulation appears within each top-dimensional simplex.
Each such appearance is described by a FaceEmbedding<dim, subdim> object, which uses this as a base class. End users should not need to refer to FaceEmbeddingBase directly.
See the FaceEmbedding template class notes for further information.
dim | the dimension of the underlying triangulation. This must be between 2 and 15 inclusive. |
subdim | the dimension of the faces of the underlying triangulation. This must be between 0 and dim-1 inclusive. |
|
inherited |
Returns a detailed text representation of this object.
This text may span many lines, and should provide the user with all the information they could want. It should be human-readable, should not contain extremely long lines (which cause problems for users reading the output in a terminal), and should end with a final newline. There are no restrictions on the underlying character set.
|
inherited |
Returns a short text representation of this object.
This text should be human-readable, should fit on a single line, and should not end with a newline. Where possible, it should use plain ASCII characters.
__str__()
.
|
inherited |
Returns a short text representation of this object using unicode characters.
Like str(), this text should be human-readable, should fit on a single line, and should not end with a newline. In addition, it may use unicode characters to make the output more pleasant to read. This string will be encoded in UTF-8.

inlineinherited |
A default implementation for detailed output.
This routine simply calls T::writeTextShort() and appends a final newline.
out | the output stream to which to write. |
