template<int dim, int spacedim = dim>
struct Triangulation< dim, spacedim >::DistortedCellList
A structure that is used as an exception object by the create_triangulation() function to indicate which cells among the coarse mesh cells are inverted or severely distorted (see the entry on distorted cells in the glossary).
Objects of this kind are thrown by the create_triangulation() and execute_coarsening_and_refinement() functions, and they can be caught in user code if this condition is to be ignored. Note, however, that such exceptions are only produced if the necessity for this check was indicated when calling the constructor of the Triangulation class.
A cell is called deformed if the determinant of the Jacobian of the mapping from reference cell to real cell is negative at least at one vertex. This computation is done using the GeometryInfo::jacobian_determinants_at_vertices function.

Destructor. Empty, but needed for the sake of exception specification, since the base class has this exception specification and the automatically generated destructor would have a different one due to member objects.
