Objects of these classes are included in the TriaLevel and TriaFaces classes.

Return a view on the indices of the objects that bound the index-th object stored by the current object. For example, if the current object stores cells, then this function returns the equivalent of an array containing the indices of the faces that bound the index-th cell.

| std::size_t internal::TriangulationImplementation::TriaObjects::memory_consumption | ( | ) | const |

| void internal::TriangulationImplementation::TriaObjects::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 using the BOOST serialization library.

Definition at line 65 of file tria_objects.h.
| std::vector<int> internal::TriangulationImplementation::TriaObjects::cells |
Vector of the objects belonging to this level. The index of the object equals the index in this container.
Definition at line 71 of file tria_objects.h.
| std::vector<int> internal::TriangulationImplementation::TriaObjects::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 100 of file tria_objects.h.
| std::vector<std::uint8_t> internal::TriangulationImplementation::TriaObjects::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 107 of file tria_objects.h.
| std::vector<bool> internal::TriangulationImplementation::TriaObjects::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 117 of file tria_objects.h.
| std::vector<bool> internal::TriangulationImplementation::TriaObjects::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 128 of file tria_objects.h.
| std::vector<BoundaryOrMaterialId> internal::TriangulationImplementation::TriaObjects::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 179 of file tria_objects.h.
| std::vector<types::manifold_id> internal::TriangulationImplementation::TriaObjects::manifold_id |
Store manifold ids. This field stores the manifold id of each object, which is a number between 0 and numbers::flat_manifold_id-1.
Definition at line 185 of file tria_objects.h.
| unsigned int internal::TriangulationImplementation::TriaObjects::next_free_single |
Counter for next_free_single_* functions
Definition at line 297 of file tria_objects.h.
| unsigned int internal::TriangulationImplementation::TriaObjects::next_free_pair |
Counter for next_free_pair_* functions
Definition at line 302 of file tria_objects.h.
| bool internal::TriangulationImplementation::TriaObjects::reverse_order_next_free_single |
Bool flag for next_free_single_* functions
Definition at line 307 of file tria_objects.h.
| std::vector<UserData> internal::TriangulationImplementation::TriaObjects::user_data |
Pointer which is not used by the library but may be accessed and set by the user to handle data local to a line/quad/etc.
Definition at line 360 of file tria_objects.h.
|
mutable |
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.
