Detailed Description

template<typename MatrixType>

◆ MGMatrixBlockVector()

template<typename MatrixType >
MGMatrixBlockVector< MatrixType >::MGMatrixBlockVector ( const bool  edge_matrices = false,
const bool  edge_flux_matrices = false

Member Function Documentation

◆ size()

template<typename MatrixType >
unsigned int MGMatrixBlockVector< MatrixType >::size ( ) const
inline

The number of blocks.

Definition at line 920 of file matrix_block.h.

◆ add()

template<typename MatrixType >
void MGMatrixBlockVector< MatrixType >::add ( size_type  row,
size_type  column,
const std::string &  name 
)
inline

Add a new matrix block at the position (row,column) in the block system. The third argument allows to give the matrix a name for later identification.

Definition at line 928 of file matrix_block.h.

◆ reinit_matrix()

template<typename MatrixType >
void MGMatrixBlockVector< MatrixType >::reinit_matrix ( const MGLevelObject< BlockSparsityPattern > &  sparsity)
inline

For matrices using a SparsityPattern, this function reinitializes each matrix in the vector with the correct pattern from the block system.

This function reinitializes the level matrices.

Definition at line 1032 of file matrix_block.h.

◆ reinit_edge()

template<typename MatrixType >
void MGMatrixBlockVector< MatrixType >::reinit_edge ( const MGLevelObject< BlockSparsityPattern > &  sparsity)
inline

For matrices using a SparsityPattern, this function reinitializes each matrix in the vector with the correct pattern from the block system.

This function reinitializes the matrices for degrees of freedom on the refinement edge.

Definition at line 1054 of file matrix_block.h.

◆ reinit_edge_flux()

template<typename MatrixType >
void MGMatrixBlockVector< MatrixType >::reinit_edge_flux ( const MGLevelObject< BlockSparsityPattern > &  sparsity)
inline

For matrices using a SparsityPattern, this function reinitializes each matrix in the vector with the correct pattern from the block system.

This function reinitializes the flux matrices over the refinement edge.

Definition at line 1080 of file matrix_block.h.

◆ clear()

template<typename MatrixType >
void MGMatrixBlockVector< MatrixType >::clear ( bool  really_clean = false)
inline

Clear the object.

Since often only clearing of the individual matrices is desired, but not removing the blocks themselves, there is an optional argument. If the argument is missing or false, all matrices will be empty, but the size of this object and the block positions will not change. If really_clean is true, then the object will contain no blocks at the end.

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 310 of file subscriptor.h.
