Detailed Description

template<int spacedim>
class TriaAccessor< 0, 1, spacedim >

This class is a specialization of TriaAccessor<structdim, dim, spacedim> for the case that structdim is zero and dim is one. This class represents vertices in a one-dimensional triangulation that is embedded in a space of dimensionality spacedim (for spacedim==dim==1 the triangulation represents a domain in \({\mathbb R}^\text{dim}\), for spacedim>dim==1 the triangulation is of a manifold embedded in a higher dimensional space).

The current specialization of the TriaAccessor<0,dim,spacedim> class for vertices of a one-dimensional triangulation exists since in the dim == 1 case vertices are also faces.

Constructor & Destructor Documentation

◆ TriaAccessor() [1/4]

template<int spacedim>
TriaAccessor< 0, 1, spacedim >::TriaAccessor ( const Triangulation< 1, spacedim > *  tria,
const VertexKind  vertex_kind,
const unsigned int  vertex_index 
)

Constructor.

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.

◆ TriaAccessor() [2/4]

template<int spacedim>
TriaAccessor< 0, 1, spacedim >::TriaAccessor ( const Triangulation< 1, spacedim > *  tria = nullptr,
const int  = 0,
const int  = 0,
const AccessorData = nullptr 
)

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.

◆ TriaAccessor() [3/4]

template<int spacedim>
template<int structdim2, int dim2, int spacedim2>
TriaAccessor< 0, 1, spacedim >::TriaAccessor ( const TriaAccessor< structdim2, dim2, spacedim2 > &  )

Constructor. Should never be called and thus produces an error.

◆ TriaAccessor() [4/4]

template<int spacedim>
template<int structdim2, int dim2, int spacedim2>
TriaAccessor< 0, 1, spacedim >::TriaAccessor ( const InvalidAccessor< structdim2, dim2, spacedim2 > &  )

Constructor. Should never be called and thus produces an error.

Member Function Documentation

◆ copy_from() [1/2]

template<int spacedim>
void TriaAccessor< 0, 1, spacedim >::copy_from ( const TriaAccessor< 0, 1, spacedim > &  )

Copy operator. Since this is only called from iterators, do not return anything, since the iterator will return itself.

◆ copy_from() [2/2]

template<int spacedim>
void TriaAccessor< 0, 1, spacedim >::copy_from ( const TriaAccessorBase< 0, 1, spacedim > &  )

Copy operator. We need this function to support generic programming, but it just throws an exception because it cannot do the required operations.

◆ state()

template<int spacedim>
static IteratorState::IteratorStates TriaAccessor< 0, 1, spacedim >::state ( )
static

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()

template<int spacedim>
static int TriaAccessor< 0, 1, spacedim >::level ( )
static

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

◆ index()

template<int spacedim>
int TriaAccessor< 0, 1, spacedim >::index ( ) const

Index of this object. Returns the global index of the vertex this object points to.

◆ get_triangulation()

template<int spacedim>
const Triangulation<1, spacedim>& TriaAccessor< 0, 1, spacedim >::get_triangulation ( ) const

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

◆ operator++()

template<int spacedim>
void TriaAccessor< 0, 1, spacedim >::operator++ ( ) const

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

◆ operator--()

template<int spacedim>
void TriaAccessor< 0, 1, spacedim >::operator-- ( ) const

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

◆ operator==()

template<int spacedim>
bool TriaAccessor< 0, 1, spacedim >::operator== ( const TriaAccessor< 0, 1, spacedim > &  ) const

Compare for equality.

◆ operator!=()

template<int spacedim>
bool TriaAccessor< 0, 1, spacedim >::operator!= ( const TriaAccessor< 0, 1, spacedim > &  ) const

Compare for inequality.

◆ operator<()

template<int spacedim>
bool TriaAccessor< 0, 1, spacedim >::operator< ( const TriaAccessor< 0, 1, spacedim > &  other) const

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.

◆ vertex_index()

template<int spacedim>
unsigned int TriaAccessor< 0, 1, spacedim >::vertex_index ( const unsigned int  i = 0) const

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.

Note
Despite the name, the index returned here is only global in the sense that it is specific to a particular Triangulation object or, in the case the triangulation is actually of type parallel::distributed::Triangulation, specific to that part of the distributed triangulation stored on the current processor.

◆ vertex()

template<int spacedim>
Point<spacedim>& TriaAccessor< 0, 1, spacedim >::vertex ( const unsigned int  i = 0) const

Return a reference to the ith vertex. If i is zero, this returns a reference to the current point to which this object refers. Otherwise, it throws an exception.

◆ center()

template<int spacedim>
Point<spacedim> TriaAccessor< 0, 1, spacedim >::center ( ) const

Return the center of this object, which of course coincides with the location of the vertex this object refers to.

◆ line()

template<int spacedim>
static typename ::internal::TriangulationImplementation:: Iterators<1, spacedim>::line_iterator TriaAccessor< 0, 1, spacedim >::line ( const unsigned int  )
static

Pointer to the ith line bounding this object. Will point to an invalid object.

◆ line_index()

template<int spacedim>
static unsigned int TriaAccessor< 0, 1, spacedim >::line_index ( const unsigned int  i)
static

Line index of the ith line bounding this object.

Implemented only for structdim>1, otherwise an exception generated.

◆ quad()

template<int spacedim>
static typename ::internal::TriangulationImplementation:: Iterators<1, spacedim>::quad_iterator TriaAccessor< 0, 1, spacedim >::quad ( const unsigned int  i)
static

Pointer to the ith quad bounding this object.

◆ quad_index()

template<int spacedim>
static unsigned int TriaAccessor< 0, 1, spacedim >::quad_index ( const unsigned int  i)
static

Quad index of the ith quad bounding this object.

Implemented only for structdim>2, otherwise an exception generated.

◆ at_boundary()

template<int spacedim>
bool TriaAccessor< 0, 1, spacedim >::at_boundary ( ) const

Return whether this point is at the boundary of the one-dimensional triangulation we deal with here.

◆ boundary_id()

template<int spacedim>
types::boundary_id TriaAccessor< 0, 1, spacedim >::boundary_id ( ) const

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.

◆ get_manifold()

template<int spacedim>
const Manifold<1, spacedim>& TriaAccessor< 0, 1, spacedim >::get_manifold ( ) const

Return a constant reference to the manifold object used for this object.

◆ manifold_id()

template<int spacedim>
types::manifold_id TriaAccessor< 0, 1, spacedim >::manifold_id ( ) const

Return the manifold indicator of this object.

◆ set_user_flag()

template<int spacedim>
void TriaAccessor< 0, 1, spacedim >::set_user_flag

Set the user flag. See GlossUserFlags for more information.

◆ recursively_clear_user_flag()

template<int spacedim>
void TriaAccessor< 0, 1, spacedim >::recursively_clear_user_flag

Clear the user flag for this and all descendants. See GlossUserFlags for more information.

Definition at line 1850 of file tria_accessor.cc.

◆ clear_user_data()

template<int spacedim>
void TriaAccessor< 0, 1, spacedim >::clear_user_data

Reset the user data to zero, independent if pointer or index. See GlossUserData for more information.

Definition at line 1863 of file tria_accessor.cc.

◆ set_user_pointer()

template<int spacedim>
void TriaAccessor< 0, 1, spacedim >::set_user_pointer ( void *  p) const

Set the user pointer to p.

Note
User pointers and user indices are mutually exclusive. Therefore, you can only use one of them, unless you call Triangulation::clear_user_data() in between.

See GlossUserData for more information.

Definition at line 1873 of file tria_accessor.cc.

◆ clear_user_pointer()

template<int spacedim>
void TriaAccessor< 0, 1, spacedim >::clear_user_pointer

Reset the user pointer to a nullptr pointer. See GlossUserData for more information.

Definition at line 1883 of file tria_accessor.cc.

◆ user_pointer()

template<int spacedim>
void * TriaAccessor< 0, 1, spacedim >::user_pointer

Access the value of the user pointer. It is in the responsibility of the user to make sure that the pointer points to something useful. You should use the new style cast operator to maintain a minimum of type safety, e.g.

Note
User pointers and user indices are mutually exclusive. Therefore, you can only use one of them, unless you call Triangulation::clear_user_data() in between. A a=static_cast<A>(cell->user_pointer());.

See GlossUserData for more information.

Definition at line 1893 of file tria_accessor.cc.

◆ recursively_set_user_pointer()

template<int spacedim>
void TriaAccessor< 0, 1, spacedim >::recursively_set_user_pointer ( void *  p) const

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.

Note
User pointers and user indices are mutually exclusive. Therefore, you can only use one of them, unless you call Triangulation::clear_user_data() in between.

See GlossUserData for more information.

Definition at line 1904 of file tria_accessor.cc.

◆ recursively_clear_user_pointer()

template<int spacedim>
void TriaAccessor< 0, 1, spacedim >::recursively_clear_user_pointer

Clear the user pointer of this object and all of its descendants. The same holds as said for the recursively_set_user_pointer() function. See GlossUserData for more information.

Definition at line 1917 of file tria_accessor.cc.

◆ set_user_index()

template<int spacedim>
void TriaAccessor< 0, 1, spacedim >::set_user_index ( const unsigned int  p) const

Set the user index to p.

Note
User pointers and user indices are mutually exclusive. Therefore, you can only use one of them, unless you call Triangulation::clear_user_data() in between. See GlossUserData for more information.

Definition at line 1930 of file tria_accessor.cc.

◆ clear_user_index()

template<int spacedim>
void TriaAccessor< 0, 1, spacedim >::clear_user_index

Reset the user index to 0. See GlossUserData for more information.

Definition at line 1940 of file tria_accessor.cc.

◆ user_index()

template<int spacedim>
unsigned int TriaAccessor< 0, 1, spacedim >::user_index

Access the value of the user index.

Note
User pointers and user indices are mutually exclusive. Therefore, you can only use one of them, unless you call Triangulation::clear_user_data() in between.

See GlossUserData for more information.

Definition at line 1950 of file tria_accessor.cc.

◆ recursively_set_user_index()

template<int spacedim>
void TriaAccessor< 0, 1, spacedim >::recursively_set_user_index ( const unsigned int  p) const

Set the user index of this object and all its children.

Note that the user index is not inherited under mesh refinement, so after mesh refinement there might be cells or faces that don't have the expected user indices. 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 index of all finer levels of the triangulation.

Note
User pointers and user indices are mutually exclusive. Therefore, you can only use one of them, unless you call Triangulation::clear_user_data() in between.

template<int spacedim>
void TriaAccessor< 0, 1, spacedim >::set_boundary_id ( const types::boundary_id  ) const

Warning
You should never set the boundary indicator of an interior face (a face not at the boundary of the domain), or set the boundary indicator of an exterior face to numbers::internal_face_boundary_id (this value is reserved for another purpose). Algorithms may not work or produce very confusing results if boundary cells have a boundary indicator of numbers::internal_face_boundary_id or if interior cells have boundary indicators other than numbers::internal_face_boundary_id. Unfortunately, the current object has no means of finding out whether it really is at the boundary of the domain and so cannot determine whether the value you are trying to set makes sense under the current circumstances.

◆ set_manifold_id()

template<int spacedim>
void TriaAccessor< 0, 1, spacedim >::set_manifold_id ( const types::manifold_id  )

template<int spacedim>
void TriaAccessor< 0, 1, spacedim >::set_all_boundary_ids ( const types::boundary_id  ) const

Set the boundary indicator of this object and all of its lower- dimensional sub-objects. Since this object only represents a single vertex, there are no lower-dimensional object and this function is equivalent to calling set_boundary_id() with the same argument.
