Detailed Description

A class that selects vectors from a list of named vectors.

Since the number of vectors in an AnyData object may grow with every nesting of applications or loops, it is important to be able to select those, which are actually used in computing residuals etc. This class organizes the selection.

It is used for instance in IntegrationWorker to determine which values, derivatives or second derivatives are actually computed.

Member Function Documentation

◆ add()

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

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.

Definition at line 424 of file vector_selector.h.

◆ initialize()

void MeshWorker::VectorSelector::initialize ( const AnyData &  src)
inline

Does the same as the function above but it is possible to select a block of the global vector. Initialize the selection field with a data vector. While add() only enters the names of vectors, which will be used in the integration loop over cells and faces, this function links the names to actual vectos in a AnyData object.

Note
This function caches the index associated with a name. Therefore, it must be called every time after the AnyData object has changed.

Definition at line 450 of file vector_selector.h.

◆ empty()

bool MeshWorker::VectorSelector::empty ( ) const
inline

Check whether any vector is selected.

Definition at line 458 of file vector_selector.h.

bool MeshWorker::VectorSelector::has_values ( ) const
inline

Return true if values are selected for any vector.

Definition at line 466 of file vector_selector.h.

◆ has_gradients()

bool MeshWorker::VectorSelector::has_gradients ( ) const
inline

Return true if gradients are selected for any vector.

Definition at line 473 of file vector_selector.h.

◆ has_hessians()

bool MeshWorker::VectorSelector::has_hessians ( ) const
inline

Return true if hessians are selected for any vector.

◆ print() [1/2]

template<class StreamType , typename DATA >
void MeshWorker::VectorSelector::print ( StreamType &  s,
const AnyData &  v 
) const
inline

Print the contents of the selection to the stream.

Definition at line 539 of file vector_selector.h.

◆ print() [2/2]

template<class StreamType >
void MeshWorker::VectorSelector::print ( StreamType &  s) const
inline

Print the number of selections to the stream.

Definition at line 530 of file vector_selector.h.

◆ memory_consumption()
