Detailed Description

template<typename T = unsigned int>
struct internal::TriangulationImplementation::Connectivity< T >

Class for storing the reduced connectivity table.

A full connectivity table contains all possible connectivities of entities of dimension d and entities of dimension d' with 0<=d,d'<=dim. However, in the library we only need the following types of connectivities:

dim-dimensional neighbors of dim-dimensional entities (connected via faces)
d-dimensional entity to it's (d-1)-dimension bounding entities
quad (2 - 3D), line (1 - 2d/3d) to vertices (0) to be able to process the user provided SubCellData during Triangulation::create_triangulation(). We call a table, which computes the corresponding entries of a full connectivity table a reduced table.

The entries of the reduced table are as follows for 1d-3d:

1D : | 0 1 2d: | 0 1 2 3d: | 0 1 2 3 —+--— —+----— —+-----— 0 | 0 | 0 | 1 | x n 1 | x 1 | x 2 | s x n 2 | s x 3 | x n

with markers highlighting the reason for the entry x:=bounding entities; n:= neighboring entities; s:=sub-cell data
