Member Function Documentation

◆ initialize()

template<int dim, int spacedim = dim, typename Number = double>
void MeshWorker::VectorDataBase< dim, spacedim, Number >::initialize ( const AnyData & )

Initialize with a AnyData object and cache the indices in the VectorSelector base class.

Note
Make sure the VectorSelector base class was filled with reasonable data before calling this function.

◆ fill()

virtual void MeshWorker::VectorDataBase< dim, spacedim, Number >::fill ( std::vector< std::vector< std::vector< Number > > > & values,

The only function added to VectorSelector is an abstract virtual function implemented in the derived class template and called by IntegrationInfo.

Depending on the selections made in our base class, this fills the first three arguments with the local data of the finite element functions. It is usually called either for the whole FESystem, or for each base element separately.

Parameters
valuesis the vector filled with the values of the finite element function in the quadrature points.
gradientsis the vector filled with the derivatives of the finite element function in the quadrature points.
hessiansis the vector filled with the second derivatives of the finite element function in the quadrature points.
feis the FEValuesBase object which is used to compute the function values. Its UpdateFlags must have been set appropriately.
indexis the local index vector. If fe refers to base elements of the system, this vector should be sorted by block and the arguments start and size below specify the subset of indices used.
componentis the first index in values, gradients and hessians entered in this function.
n_compis the number of components to be filled.
startis the first index of this block in indices, or zero if no base elements are used.
sizeis the number of dofs per cell of the current element or base element.

Reimplemented in MeshWorker::VectorData< VectorType, dim, spacedim >, and MeshWorker::VectorData< VectorType, dim, dim >.

◆ mg_fill()

template<int dim, int spacedim = dim, typename Number = double>
virtual void MeshWorker::VectorDataBase< dim, spacedim, Number >::mg_fill ( std::vector< std::vector< std::vector< Number > > > & values,
std::vector< std::vector< std::vector< Tensor< 1, spacedim, Number > > > > & gradients,
std::vector< std::vector< std::vector< Tensor< 2, spacedim, Number > > > > & hessians,
const FEValuesBase< dim, spacedim > & fe,
const unsigned int level,
const std::vector< types::global_dof_index > & index,
const unsigned int component,
const unsigned int n_comp,
const unsigned int start,
const unsigned int size ) const
virtual

Fill the local data vector from level vectors. Performs exactly what the other fill() does, but uses the cell level to access a single level out of a hierarchy of level vectors, instead of a global data vector on the active cells.

Reimplemented in MeshWorker::VectorData< VectorType, dim, spacedim >, and MeshWorker::VectorData< VectorType, dim, dim >.

◆ add()

void MeshWorker::VectorSelector::add ( const std::string & name,
const bool values = true,
const bool gradients = false,
const bool hessians = false )
inlineinherited

Add a vector to the selection of finite element functions. The arguments are the name of the vector and indicators, which information is to be extracted from the vector. The name refers to an entry in a AnyData object, which will be identified by initialize(). The three bool parameters indicate, whether values, gradients and Hessians of the finite element function are to be computed on each cell or face.

◆ memory_consumption()

std::size_t MeshWorker::VectorSelector::memory_consumption ( ) const
inlineinherited

The memory used by this object.

Definition at line 547 of file vector_selector.h.

◆ subscribe()

void Subscriptor::subscribe ( std::atomic< bool > *const validity,
const std::string & identifier = "" ) const
inherited

Subscribes a user of the object by storing the pointer validity. The subscriber may be identified by text supplied as identifier.

Definition at line 135 of file subscriptor.cc.

◆ unsubscribe()

void Subscriptor::unsubscribe ( std::atomic< bool > *const validity,
const std::string & identifier = "" ) const
inherited

Unsubscribes a user from the object.

Note
The identifier and the validity pointer must be the same as the one supplied to subscribe().

Definition at line 155 of file subscriptor.cc.

◆ n_subscriptions()

unsigned int Subscriptor::n_subscriptions ( ) const
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.

Definition at line 300 of file subscriptor.h.

◆ list_subscribers() [1/2]

template<typename StreamType >
void Subscriptor::list_subscribers ( StreamType & stream) const
inlineinherited

List the subscribers to the input stream.

Definition at line 317 of file subscriptor.h.

◆ list_subscribers() [2/2]

void Subscriptor::list_subscribers ( ) const
inherited

List the subscribers to deallog.

Definition at line 203 of file subscriptor.cc.

◆ serialize()

template<class Archive >
void Subscriptor::serialize ( Archive & ar,
const unsigned int version )
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.

◆ check_no_subscribers()

void Subscriptor::check_no_subscribers ( ) const
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.

Note
Since this function is just a consistency check it does nothing in release mode.
If this function is called when there is an uncaught exception then, rather than aborting, this function prints an error message to the standard error stream and returns.

Definition at line 52 of file subscriptor.cc.

Definition at line 180 of file vector_selector.h.

◆ counter

std::atomic<unsigned int> Subscriptor::counter
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.

◆ counter_map

std::map<std::string, unsigned int> Subscriptor::counter_map
mutableprivateinherited

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

Definition at line 224 of file subscriptor.h.

◆ validity_pointers

std::vector<std::atomic<bool> *> Subscriptor::validity_pointers
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.

◆ object_info

const std::type_info* Subscriptor::object_info
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.

◆ mutex

std::mutex Subscriptor::mutex
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().
