This class acts as a collection of finite element objects used in the DoFHandler.
It implements the concepts stated in the hpCollections module described in the doxygen documentation.
In addition to offering access to the elements of the collection, this class provides access to the maximal number of degrees of freedom per vertex, line, etc, to allow allocation of as much memory as is necessary in the worst case when using the finite elements associated with the cells of a triangulation.
This class has not yet been implemented for the use in the codimension one case (spacedim != dim
).

hp::FECollection< dim, spacedim >::FECollection  (  ) 
Default constructor. Leads to an empty collection that can later be filled using push_back(). Establishes a hierarchy of finite elements corresponding to their index in the collection.
Definition at line 31 of file fe_collection.cc.

explicit 
Conversion constructor. This constructor creates a FECollection from a single finite element. More finite element objects can be added with push_back(), if desired, though it would probably be clearer to add all mappings the same way.
Definition at line 39 of file fe_collection.cc.

explicit 
Constructor. This constructor creates a FECollection from one or more finite element objects passed to the constructor. For this call to be valid, all arguments need to be of types derived from class FiniteElement<dim,spacedim>.
Definition at line 880 of file fe_collection.h.
hp::FECollection< dim, spacedim >::FECollection  (  const std::vector< const FiniteElement< dim, spacedim > * > &  fes  ) 
Constructor. Same as above but for any number of elements. Pointers to the elements are passed in a vector to this constructor. As above, the finite element objects pointed to by the argument are not actually used other than to create copies internally. Consequently, you can delete these pointers immediately again after calling this constructor.

void hp::FECollection< dim, spacedim >::push_back  (  const FiniteElement< dim, spacedim > &  new_fe  ) 
Add a finite element. This function generates a copy of the given element, i.e. you can do things like push_back(FE_Q<dim>(1));
. The internal copy is later destroyed by this object upon destruction of the entire collection.
When a new element is added, it needs to have the same number of vector components as all other elements already in the collection.
Definition at line 64 of file fe_collection.cc.

inline 
Return the number of vector components of the finite elements in this collection. This number must be the same for all elements in the collection.
This function calls FiniteElement::n_components. See the glossary for more information.
Definition at line 900 of file fe_collection.h.
unsigned int hp::FECollection< dim, spacedim >::n_blocks  (  )  const 
Return the number of vector blocks of the finite elements in this collection. While this class ensures that all elements stored in it have the same number of vector components, there is no such guarantees for the number of blocks each element is made up of (an element may have fewer blocks than vector components; see the glossary for more information). For example, you may have an FECollection object that stores one copy of an FESystem with dim
FE_Q objects and one copy of an FE_RaviartThomas element. Both have dim
vector components but while the former has dim
blocks the latter has only one. Consequently, this function will throw an assertion if the number of blocks is not the same for all elements. If they are the same, this function returns the result of FiniteElement::n_blocks().
Definition at line 847 of file fe_collection.cc.
unsigned int hp::FECollection< dim, spacedim >::max_degree  (  )  const 
Return the maximum of values returned by FiniteElement::get_degree() over all elements of this collection.
Definition at line 947 of file fe_collection.h.
unsigned int hp::FECollection< dim, spacedim >::max_dofs_per_vertex  (  )  const 
Return the maximal number of degrees of freedom per vertex over all elements of this collection.
Definition at line 962 of file fe_collection.h.
unsigned int hp::FECollection< dim, spacedim >::max_dofs_per_line  (  )  const 
Return the maximal number of degrees of freedom per line over all elements of this collection.
Definition at line 977 of file fe_collection.h.
unsigned int hp::FECollection< dim, spacedim >::max_dofs_per_quad  (  )  const 
Return the maximal number of degrees of freedom per quad over all elements of this collection.
Definition at line 992 of file fe_collection.h.
unsigned int hp::FECollection< dim, spacedim >::max_dofs_per_hex  (  )  const 
Return the maximal number of degrees of freedom per hex over all elements of this collection.
Definition at line 1007 of file fe_collection.h.
unsigned int hp::FECollection< dim, spacedim >::max_dofs_per_face  (  )  const 
Return the maximal number of degrees of freedom per face over all elements of this collection.
Definition at line 1022 of file fe_collection.h.
unsigned int hp::FECollection< dim, spacedim >::max_dofs_per_cell  (  )  const 
Return the maximal number of degrees of freedom per cell over all elements of this collection.
Definition at line 1037 of file fe_collection.h.
const MappingCollection< dim, spacedim > & hp::FECollection< dim, spacedim >::get_reference_cell_default_linear_mapping  (  )  const 
Return a mapping collection that consists of the default linear mappings matching the reference cells for each hp index. More details may be found in the documentation for ReferenceCell::get_default_linear_mapping().
Definition at line 82 of file fe_collection.cc.
bool hp::FECollection< dim, spacedim >::hp_constraints_are_implemented  (  )  const 
Return whether all elements in this collection implement the hanging node constraints in the new way, which has to be used to make elements "hpcompatible". If this is not the case, the function returns false, which implies, that at least one element in the FECollection does not support the new face interface constraints. On the other hand, if this method does return true, this does not imply that the hpmethod will work!
This behavior is related to the fact, that FiniteElement classes, which provide the new style hanging node constraints might still not provide them for all possible cases. If FE_Q and FE_RaviartThomas elements are included in the FECollection and both properly implement the get_face_interpolation_matrix method, this method will return true. But the get_face_interpolation_matrix might still fail to find an interpolation matrix between these two elements.
Definition at line 1051 of file fe_collection.h.
std::vector< std::map< unsigned int, unsigned int > > hp::FECollection< dim, spacedim >::hp_vertex_dof_identities  (  const std::set< unsigned int > &  fes  )  const 
This function combines the functionality of the FiniteElement::hp_vertex_dof_identities() into multiway comparisons. Given a set of elements (whose indices are provided as argument), this function determines identities between degrees of freedom of these elements at a vertex.
The function returns a vector of such identities, where each element of the vector is a set of pairs (fe_index,dof_index)
that identifies the fe_index
(an element of the fes
argument to this function) of an element and the dof_index
indicates the howmanyth degree of freedom of that element on a vertex participates in this identity. Now, every fe_index
can appear only once in these sets (for each identity, only one degree of freedom of a finite element can be involved – otherwise we would have identities between different DoFs of the same element, which would make the element not unisolvent), and as a consequence the function does not actually return a set of (fe_index,dof_index)
pairs for each identity, but instead a std::map
from fe_index
to dof_index
, which is conceptually of course equivalent to a std::set
of pairs, but in practice is easier to query.

std::vector< std::map< unsigned int, unsigned int > > hp::FECollection< dim, spacedim >::hp_line_dof_identities  (  const std::set< unsigned int > &  fes  )  const

std::set< unsigned int > hp::FECollection< dim, spacedim >::find_common_fes  (  const std::set< unsigned int > &  fes, 
const unsigned int  codim = 0 

)  const 
Return the indices of finite elements in this FECollection that dominate all elements associated with the provided set of indices fes
.
You may find information about the domination behavior of finite elements in their respective class documentation or in the implementation of their inherited member function FiniteElement::compare_for_domination(). Consider that a finite element may or may not dominate itself (e.g. FE_Nothing elements).
For example, if a FECollection consists of {FE_Q(1),FE_Q(2),FE_Q(3),FE_Q(4)}
elements and we are looking for the finite elements that dominate the middle elements of this collection (i.e., fes
is {1,2}
), then the answer is {FE_Q(1),FE_Q(2)
and therefore this function will return their indices in the FECollection, namely {0,1}
.
The codim
parameter describes the codimension of the investigated subspace and specifies that it is subject to this comparison. See FiniteElement::compare_for_domination() for more information.

std::set< unsigned int > hp::FECollection< dim, spacedim >::find_enclosing_fes  (  const std::set< unsigned int > &  fes,

unsigned int hp::FECollection< dim, spacedim >::find_dominating_fe  (  const std::set< unsigned int > &  fes, 
const unsigned int  codim = 0 

)  const 
Return the index of a finite element from the provided set of indices fes
that dominates all other elements of this very set.
You may find information about the domination behavior of finite elements in their respective class documentation or in the implementation of their inherited member function FiniteElement::compare_for_domination(). Consider that a finite element may or may not dominate itself (e.g. FE_Nothing elements).
If this set consists of exactly one element, we consider it to be the dominating one and return its corresponding index. Further, if the function is not able to find a finite element at all, it returns numbers::invalid_fe_index.
For example, if a FECollection consists of {FE_Q(1),FE_Q(2),FE_Q(3),FE_Q(4)}
elements and we are looking for the dominating finite element among the middle elements of this collection (i.e., fes
is {1,2}
), then the answer is FE_Q(2) and therefore this function will return its index in the FECollection, namely 1
.
It is of course possible that there is more than one element that dominates all selected elements. For example, if the collection consists of {FE_Q(1),FE_Q(1),FE_Q(2),FE_Q(2)}
and fes
covers all indices, then one could return zero or one. In that case, the function returns either 0
or 1
since there is no tiebreaker between the two.

Definition at line 589 of file fe_collection.cc.
std::vector< unsigned int > hp::FECollection< dim, spacedim >::get_hierarchy_sequence  (  const unsigned int  fe_index = 0  )  const 
Returns a sequence of FE indices that corresponds to the registered hierarchy in ascending order, i.e., FE indices are sorted from lowest to highest level.
Multiple sequences of FE indices are possible with a single custom hierarchy that can be registered with set_hierarchy(). This function will return the sequence that contains the userprovided index fe_index
which could be located anywhere inside the sequence. The default hierarchy set via set_default_hierarchy(), which corresponds to FE indices in ascending order, consists of only one sequence.
This function can be used, for example, to verify that your provided hierarchy covers all elements in the desired order.
Only one sequence of FE indices exists if the size of the returned container equals the number of elements of this object, i.e., FECollection::size().

Function returning the index of the finite element following the given fe_index

will be returned. If fe_index
already corresponds to the last index, the last index will be returned. A custom hierarchy can be supplied via the member function set_hierarchy().

will be returned. If fe_index
already corresponds to the first index, the first index will be returned. A custom hierarchy can be supplied via the member function set_hierarchy().

inlineinherited 
Return the present number of subscriptions to this object. This allows to use this class for reference counted lifetime determination where the last one to unsubscribe also deletes the object.

inlineinherited 
Read or write the data of this object to or from a stream for the purpose of serialization using the BOOST serialization library.
This function does not actually serialize any of the member variables of this class. The reason is that what this class stores is only who subscribes to this object, but who does so at the time of storing the contents of this object does not necessarily have anything to do with who subscribes to the object when it is restored. Consequently, we do not want to overwrite the subscribers at the time of restoring, and then there is no reason to write the subscribers out in the first place.
Definition at line 309 of file subscriptor.h.

privatenoexceptinherited 
Check that there are no objects subscribing to this object. If this check passes then it is safe to destroy the current object. It this check fails then this function will either abort or print an error message to deallog (by using the AssertNothrow mechanism), but will not throw an exception.

privateinherited 
The real container, which stores pointers to the different objects.
Definition at line 236 of file collection.h.

mutableprivateinherited 
Store the number of objects which subscribed to this object. Initially, this number is zero, and upon destruction it shall be zero again (i.e. all objects which subscribed should have unsubscribed again).
The creator (and owner) of an object is counted in the map below if HE manages to supply identification.
We use the mutable
keyword in order to allow subscription to constant objects also.
This counter may be read from and written to concurrently in multithreaded code: hence we use the std::atomic
class template.
Definition at line 218 of file subscriptor.h.

mutableprivateinherited 
In this map, we count subscriptions for each different identification string supplied to subscribe().

mutableprivateinherited 
In this vector, we store pointers to the validity bool in the SmartPointer objects that subscribe to this class.
Definition at line 240 of file subscriptor.h.

mutableprivateinherited 
Pointer to the typeinfo object of this object, from which we can later deduce the class name. Since this information on the derived class is neither available in the destructor, nor in the constructor, we obtain it in between and store it here.
Definition at line 248 of file subscriptor.h.

staticprivateinherited 
A mutex used to ensure data consistency when accessing the mutable
members of this class. This lock is used in the subscribe() and unsubscribe() functions, as well as in list_subscribers()
