enum internal::Triangulation::TriaObjects::UserDataType [protected] |
internal::Triangulation::TriaObjects< G >::TriaObjects | ( | ) | [inline] |
Constructor resetting some data.
void internal::Triangulation::TriaObjects< G >::reserve_space | ( | const unsigned int | new_objs_in_pairs, | |
const unsigned int | new_objs_single = 0 | |||
) |
Assert that enough space is allocated to accomodate new_objs_in_pairs
new objects, stored in pairs, plus new_obj_single
stored individually. This function does not only call vector::reserve()
, but does really append the needed elements.
In 2D e.g. refined lines have to be stored in pairs, whereas new lines in the interior of refined cells can be stored as single lines.
Reimplemented in internal::Triangulation::TriaObjectsQuad3D.
typename ::Triangulation<dim,spacedim>::raw_line_iterator internal::Triangulation::TriaObjects< G >::next_free_single_line | ( | const ::Triangulation< dim, spacedim > & | tria | ) | [inline] |

bool internal::Triangulation::TriaObjects< G >::face_orientation | ( | const unsigned int | cell, | |
const unsigned int | face | |||
) | const [inline] |
The orientation of the face number face
of the cell with number cell
. The return value is true
, if the normal vector points the usual way (GeometryInfo::unit_normal_orientation) and false
else.
The result is always true
in this class, but derived classes will reimplement this.

void internal::Triangulation::TriaObjects< G >::monitor_memory | ( | const unsigned int | true_dimension | ) | const |
Check the memory consistency of the different containers. Should only be called with the prepro flag DEBUG
set. The function should be called from the functions of the higher TriaLevel classes.

unsigned int internal::Triangulation::TriaObjects< G >::memory_consumption | ( | ) | const |
Determine an estimate for the memory consumption (in bytes) of this object.

std::vector<G> internal::Triangulation::TriaObjects< G >::cells |
Vector of the objects belonging to this level. The index of the object equals the index in this container.
std::vector<int> internal::Triangulation::TriaObjects< G >::children |
Index of the even children of an object. Since when objects are refined, all children are created at the same time, they are appended to the list at least in pairs after each other. We therefore only store the index of the even children, the uneven follow immediately afterwards.
If an object has no children, -1 is stored in this list. An object is called active if it has no children. The function TriaAccessorBase::has_children() tests for this.
std::vector<RefinementCase<G::dimension> > internal::Triangulation::TriaObjects< G >::refinement_cases |
Store the refinement case each of the cells is refined with. This vector might be replaced by vector<vector<bool> > (dim, vector<bool> (n_cells)) which is more memory efficient.
std::vector<bool> internal::Triangulation::TriaObjects< G >::used |
Vector storing whether an object is used in the cells
vector.
Since it is difficult to delete elements in a vector
, when an element is not needed any more (e.g. after derefinement), it is not deleted from the list, but rather the according used
flag is set to false
.
std::vector<bool> internal::Triangulation::TriaObjects< G >::user_flags |
Make available a field for user data, one bit per object. This field is usually used when an operation runs over all cells and needs information whether another cell (e.g. a neighbor) has already been processed.
You can clear all used flags using Triangulation::clear_user_flags().
Referenced by internal::Triangulation::TriaObjects< G >::clear_user_flags().
std::vector<unsigned char> internal::Triangulation::TriaObjects< G >::material_id |
Store boundary and material data. For example, in one dimension, this field stores the material id of a line, which is a number between 0 and 254. In more than one dimension, lines have no material id, but they may be at the boundary; then, we store the boundary indicator in this field, which denotes to which part of the boundary this line belongs and which boundary conditions hold on this part. The boundary indicator also is a number between zero and 254; the id 255 is reserved for lines in the interior and may be used to check whether a line is at the boundary or not, which otherwise is not possible if you don't know which cell it belongs to.

UserDataType internal::Triangulation::TriaObjects< G >::user_data_type [mutable, protected] |
In order to avoid confusion between user pointers and indices, this enum is set by the first function accessing either and subsequent access will not be allowed to change the type of data accessed.
