Detailed Description

template<int dim, int spacedim = dim, typename number = double>
class MeshWorker::LocalIntegrator< dim, spacedim, number >

A local integrator object, which can be used to simplify the call of loop(). Instead of providing the three local integration functions separately, we bundle them as virtual functions in this class.

Additionally, since we cannot have a virtual null function, we provide flags, which allow us to indicate, whether we want to integrate on boundary and interior faces. These flags are true by default, but can be modified by applications to speed up the loop.

If a function is not overloaded in a derived class, but its usage flag is true, the function will cause an exception ExcPureFunction.

◆ LocalIntegrator() [2/2]

template<int dim, int spacedim, typename number >
MeshWorker::LocalIntegrator< dim, spacedim, number >::LocalIntegrator ( bool  use_cell,
bool  use_boundary,
bool  use_face 
)

The constructor setting integration flags to specified values.

Definition at line 69 of file mesh_worker.cc.

◆ ~LocalIntegrator()

template<int dim, int spacedim = dim, typename number = double>
virtual MeshWorker::LocalIntegrator< dim, spacedim, number >::~LocalIntegrator ( )
overridevirtualdefault

The empty virtual destructor.

Member Function Documentation

◆ cell()

template<int dim, int spacedim, typename number >
void MeshWorker::LocalIntegrator< dim, spacedim, number >::cell ( DoFInfo< dim, spacedim, number > &  dinfo,
IntegrationInfo< dim, spacedim > &  info 
) const
virtual

Virtual function for integrating on cells. Throws exception PureFunctionCalled if not overloaded by a derived class.

Definition at line 81 of file mesh_worker.cc.

◆ boundary()

template<int dim, int spacedim, typename number >
void MeshWorker::LocalIntegrator< dim, spacedim, number >::boundary ( DoFInfo< dim, spacedim, number > &  dinfo,
IntegrationInfo< dim, spacedim > &  info 
) const
virtual

Virtual function for integrating on boundary faces. Throws exception PureFunctionCalled if not overloaded by a derived class.

Definition at line 91 of file mesh_worker.cc.

◆ face()

template<int dim, int spacedim, typename number >
void MeshWorker::LocalIntegrator< dim, spacedim, number >::face ( DoFInfo< dim, spacedim, number > &  dinfo1,
DoFInfo< dim, spacedim, number > &  dinfo2,
IntegrationInfo< dim, spacedim > &  info1,
IntegrationInfo< dim, spacedim > &  info2 
) const
virtual

Virtual function for integrating on interior faces. Throws exception PureFunctionCalled if not overloaded by a derived class.

Definition at line 101 of file mesh_worker.cc.

◆ 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 136 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 156 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 204 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.

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.

Member Data Documentation

◆ use_cell

template<int dim, int spacedim = dim, typename number = double>
bool MeshWorker::LocalIntegrator< dim, spacedim, number >::use_cell

The flag indicating whether the cell integrator cell() is to be used in the loop. Defaults to true.

Definition at line 103 of file local_integrator.h.

◆ use_boundary

template<int dim, int spacedim = dim, typename number = double>
bool MeshWorker::LocalIntegrator< dim, spacedim, number >::use_boundary

The flag indicating whether the boundary integrator boundary() is to be used in the loop. Defaults to true.

Definition at line 109 of file local_integrator.h.

◆ use_face

template<int dim, int spacedim = dim, typename number = double>
bool MeshWorker::LocalIntegrator< dim, spacedim, number >::use_face

The flag indicating whether the interior face integrator face() is to be used in the loop. Defaults to true.

Definition at line 115 of file local_integrator.h.

◆ input_vector_names

template<int dim, int spacedim = dim, typename number = double>
std::vector<std::string> MeshWorker::LocalIntegrator< dim, spacedim, number >::input_vector_names

The names of the input vectors. If this vector is nonempty, it can be used by application programs to automatically select and verify the input vectors used for integration.

Note
This variable is currently not used by the library, but it is provided to help develop application programs.

Definition at line 125 of file local_integrator.h.

◆ output_names

template<int dim, int spacedim = dim, typename number = double>
std::vector<std::string> MeshWorker::LocalIntegrator< dim, spacedim, number >::output_names

The names of the results produced. If this vector is nonempty, it can be used by application programs to automatically assign names to output values and/or verify the names of vectors.

Note
This variable is currently not used by the library, but it is provided to help develop application programs.
