Specialization of the general DoFAccessor class template for the case of zero-dimensional objects (a vertex) that are the face of a one-dimensional cell in spacedim space dimensions. Since vertices function differently than general faces, this class does a few things differently than the general template, but the interface should look the same.

DoFAccessor< 0, 1, spacedim, level_dof_access >::DoFAccessor | ( | ) |
Default constructor. Provides an accessor that can't be used.
DoFAccessor< 0, 1, spacedim, level_dof_access >::DoFAccessor | ( | const Triangulation< 1, spacedim > * | tria, |
const typename TriaAccessor< 0, 1, spacedim >::VertexKind | vertex_kind, | ||
const unsigned int | vertex_index, | ||
const DoFHandler< 1, spacedim > * | dof_handler ) |
Constructor to be used if the object here refers to a vertex of a one-dimensional triangulation, i.e. a face of the triangulation.
Since there is no mapping from vertices to cells, an accessor object for a point has no way to figure out whether it is at the boundary of the domain or not. Consequently, the second argument must be passed by the object that generates this accessor – e.g. a 1d cell that can figure out whether its left or right vertex are at the boundary.
The third argument is the global index of the vertex we point to.
The fourth argument is a pointer to the DoFHandler object.
This iterator can only be called for one-dimensional triangulations.
DoFAccessor< 0, 1, spacedim, level_dof_access >::DoFAccessor | ( | const Triangulation< 1, spacedim > * | , |
const int | = 0, | ||
const int | = 0, | ||
const DoFHandler< 1, spacedim > * | dof_handler = 0 ) |
Constructor. This constructor exists in order to maintain interface compatibility with the other accessor classes. However, it doesn't do anything useful here and so may not actually be called except to default-construct iterator objects.
DoFAccessor< 0, 1, spacedim, level_dof_access >::DoFAccessor | ( | const InvalidAccessor< structdim2, dim2, spacedim2 > & | ) |
Conversion constructor. This constructor exists to make certain constructs simpler to write in dimension independent code. For example, it allows assigning a face iterator to a line iterator, an operation that is useful in 2d but doesn't make any sense in 3d. The constructor here exists for the purpose of making the code conform to C++ but it will unconditionally abort; in other words, assigning a face iterator to a line iterator is better put into an if-statement that checks that the dimension is two, and assign to a quad iterator in 3d (an operator that, without this constructor would be illegal if we happen to compile for 2d).
DoFAccessor< 0, 1, spacedim, level_dof_access >::DoFAccessor | ( | const DoFAccessor< structdim2, dim2, spacedim2, level_dof_access2 > & | ) |
Another conversion operator between objects that don't make sense, just like the previous one.

Copy constructor.

Destructor.

delete |
Copy operator. These operators are usually used in a context like iterator a,b; *a=*b;
. Presumably, the intent here is to copy the object pointed to by b
to the object pointed to by a
. However, the result of dereferencing an iterator is not an object but an accessor; consequently, this operation is not useful for iterators on DoF handler objects. Consequently, this operator is declared as deleted and can not be used.
|
defaultnoexcept |
Move assignment operator.
const DoFHandler< 1, spacedim > & DoFAccessor< 0, 1, spacedim, level_dof_access >::get_dof_handler | ( | ) | const |
Return a handle on the DoFHandler object which we are using.
void DoFAccessor< 0, 1, spacedim, level_dof_access >::copy_from | ( | const DoFAccessor< 0, 1, spacedim, level_dof_access2 > & | a | ) |
Implement the copy operator needed for the iterator classes.
void DoFAccessor< 0, 1, spacedim, level_dof_access >::copy_from | ( | const TriaAccessorBase< 0, 1, spacedim > & | da | ) |
Copy operator used by the iterator class. Keeps the previously set dof handler, but sets the object coordinates of the TriaAccessor.
TriaIterator< DoFAccessor< 0, 1, spacedim, level_dof_access > > DoFAccessor< 0, 1, spacedim, level_dof_access >::child | ( | const unsigned int | c | ) | const |
Return an invalid iterator of a type that represents pointing to a child of the current object. The object is invalid because points (as represented by the current class) do not have children.
typename::internal::DoFHandlerImplementation::Iterators< 1, spacedim, level_dof_access >::line_iterator DoFAccessor< 0, 1, spacedim, level_dof_access >::line | ( | const unsigned int | i | ) | const |
Pointer to the ith
line bounding this object.
Since meshes with dimension 1 do not have quads this method just throws an exception.
typename::internal::DoFHandlerImplementation::Iterators< 1, spacedim, level_dof_access >::quad_iterator DoFAccessor< 0, 1, spacedim, level_dof_access >::quad | ( | const unsigned int | i | ) | const |
Pointer to the ith
quad bounding this object.

void DoFAccessor< 0, 1, spacedim, level_dof_access >::get_dof_indices | ( | std::vector< types::global_dof_index > & | dof_indices, |
const types::fe_index | fe_index = numbers::invalid_fe_index ) const |
Return the global indices of the degrees of freedom located on this object in the standard ordering defined by the finite element. This function is only available on active objects (see this glossary entry).
The present vertex must belong to an active cell (and not artificial in a parallel distributed computation).
The vector has to have the right size before being passed to this function.
The last argument denotes the finite element index. For the standard DoFHandler class, this value must be equal to its default value since that class only supports the same finite element on all cells anyway.
However, when the relevant DoFHandler has hp-capabilities, different finite element objects may be used on different cells. On faces between two cells, as well as vertices, there may therefore be two sets of degrees of freedom, one for each of the finite elements used on the adjacent cells. In order to specify which set of degrees of freedom to work on, the last argument is used to disambiguate. Finally, if this function is called for a cell object, there can only be a single set of degrees of freedom, and fe_index has to match the result of active_fe_index().
For cells, there is only a single possible finite element index (namely the one for that cell, returned by cell->active_fe_index
. Consequently, the derived DoFCellAccessor class has an overloaded version of this function that calls the present function with cell->active_fe_index
as last argument.
void DoFAccessor< 0, 1, spacedim, level_dof_access >::get_mg_dof_indices | ( | const int | level, |
std::vector< types::global_dof_index > & | dof_indices, | ||
const types::fe_index | fe_index = numbers::invalid_fe_index ) const |
Return the global multilevel indices of the degrees of freedom that live on the current object with respect to the given level within the multigrid hierarchy. The indices refer to the local numbering for the level this line lives on.
types::global_dof_index DoFAccessor< 0, 1, spacedim, level_dof_access >::vertex_dof_index | ( | const unsigned int | vertex, |
const unsigned int | i, | ||
const types::fe_index | fe_index = numbers::invalid_fe_index ) const |
Global DoF index of the i degree associated with the vertexth
vertex of the present cell.

unsigned int DoFAccessor< 0, 1, spacedim, level_dof_access >::n_active_fe_indices | ( | ) | const |
Return the number of finite elements that are active on a given object.
Since vertices do not store the information necessary for this to be calculated, this method just raises an exception and only exists to enable dimension-independent programming.

Return the n-th

Copy operator. Since this is only called from iterators, do not return anything, since the iterator will return itself.
|
staticinherited |
Return the state of the iterator. Since an iterator to points can not be incremented or decremented, its state remains constant, and in particular equal to IteratorState::valid.

Level of this object. Vertices have no level, so this function always returns zero.

Return a reference to the triangulation which the object pointed to by this class belongs to.

This operator advances the iterator to the next element. For points, this operation is not defined, so you can't iterate over point iterators.

Comparison operator for accessors. This operator is used when comparing iterators into objects of a triangulation, for example when putting them into a std::map
.
This operator simply compares the global index of the vertex the current object points to.
|
inherited |
Return the global index of i-th vertex of the current object. If i is zero, this returns the index of the current point to which this object refers. Otherwise, it throws an exception.
Note that the returned value is only the index of the geometrical vertex. It has nothing to do with possible degrees of freedom associated with it. For this, see the DoFAccessor::vertex_dof_index
functions.

|
inherited |
Return the boundary indicator of this object. The convention for one dimensional triangulations is that left end vertices (of each line segment from which the triangulation may be constructed) have boundary indicator zero, and right end vertices have boundary indicator one, unless explicitly set differently.
If the return value is the special value numbers::internal_face_boundary_id, then this object is in the interior of the domain.

Set the user pointer of this object and all its children to the given value. This is useful for example if all cells of a certain subdomain, or all faces of a certain part of the boundary should have user pointers pointing to objects describing this part of the domain or boundary.
Note that the user pointer is not inherited under mesh refinement, so after mesh refinement there might be cells or faces that don't have user pointers pointing to the describing object. In this case, simply loop over all the elements of the coarsest level that has this information, and use this function to recursively set the user pointer of all finer levels of the triangulation.
