General template for information belonging to the geometrical objects of a triangulation, i.e. lines, quads, hexahedra... Apart from the vector of objects additional information is included, namely vectors indicating the children, the used-status, user-flags, material-ids..
Objects of these classes are included in the TriaLevel and TriaFaces classes.

| void internal::TriangulationImplementation::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 accommodate 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.

| ::TriaRawIterator<::TriaAccessor<G::dimension, dim, spacedim> > internal::TriangulationImplementation::TriaObjects< G >::next_free_single_object | ( | const ::Triangulation< dim, spacedim > & | tria | ) |
Return an iterator to the next free slot for a single object. This function is only used by Triangulation::execute_refinement() in 3D.
| ::TriaRawIterator<::TriaAccessor<G::dimension, dim, spacedim> > internal::TriangulationImplementation::TriaObjects< G >::next_free_pair_object | ( | const ::Triangulation< dim, spacedim > & | tria | ) |
Return an iterator to the next free slot for a pair of objects. This function is only used by Triangulation::execute_refinement() in 3D.
| typename ::Triangulation<dim, spacedim>::raw_hex_iterator internal::TriangulationImplementation::TriaObjects< G >::next_free_hex | ( | const ::Triangulation< dim, spacedim > & | tria, |
| const unsigned int | level | ||
| ) |
Return an iterator to the next free slot for a pair of hexes. Only implemented for G=Hexahedron.
| void internal::TriangulationImplementation::TriaObjects< G >::clear | ( | ) |
Clear all the data contained in this object.
Definition at line 394 of file tria_objects.cc.
|
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::TriangulationImplementation::TriaObjects< G >::monitor_memory | ( | const unsigned int | true_dimension | ) | const |
Check the memory consistency of the different containers. Should only be called with the preprocessor flag DEBUG set. The function should be called from the functions of the higher TriaLevel classes.
| std::size_t internal::TriangulationImplementation::TriaObjects< G >::memory_consumption | ( | ) | const |
Determine an estimate for the memory consumption (in bytes) of this object.
Definition at line 428 of file tria_objects.cc.
| void internal::TriangulationImplementation::TriaObjects< G >::serialize | ( | Archive & | ar, |
| const unsigned int | version | ||

Read or write the data of this object to or from a stream for the purpose of serialization
Definition at line 729 of file tria_objects.h.
| std::vector<G> internal::TriangulationImplementation::TriaObjects< G >::cells |
Vector of the objects belonging to this level. The index of the object equals the index in this container.
Definition at line 78 of file tria_objects.h.
| std::vector<int> internal::TriangulationImplementation::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.
Definition at line 91 of file tria_objects.h.
| std::vector<RefinementCase<G::dimension> > internal::TriangulationImplementation::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.
Definition at line 98 of file tria_objects.h.
| std::vector<bool> internal::TriangulationImplementation::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.
Definition at line 108 of file tria_objects.h.
| std::vector<bool> internal::TriangulationImplementation::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().
Definition at line 119 of file tria_objects.h.
| std::vector<BoundaryOrMaterialId> internal::TriangulationImplementation::TriaObjects< G >::boundary_or_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 numbers::invalid_material_id-1. 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 numbers::internal_face_boundary_id-1; the id numbers::internal_face_boundary_id 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.
Definition at line 169 of file tria_objects.h.
| std::vector<types::manifold_id> internal::TriangulationImplementation::TriaObjects< G >::manifold_id |
Store manifold ids. This field stores the manifold id of each object, which is a number between 0 and numbers::invalid_manifold_id-1.

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.
