Detailed Description

template<typename MatrixType>
class MatrixBlockVector< MatrixType >

A vector of MatrixBlock, which is implemented using shared pointers, in order to allow for copying and rearranging. Each matrix block can be identified by name.

Member Typedef Documentation

◆ size_type

template<typename MatrixType >
using MatrixBlockVector< MatrixType >::size_type = types::global_dof_index

Declare type for container size.

Definition at line 360 of file matrix_block.h.

◆ value_type

template<typename MatrixType >
using MatrixBlockVector< MatrixType >::value_type = MatrixBlock<MatrixType>

The type of object stored.

Definition at line 365 of file matrix_block.h.

◆ ptr_type

template<typename MatrixType >
using MatrixBlockVector< MatrixType >::ptr_type = std::shared_ptr<value_type>

The pointer type used for storing the objects. We use a shard pointer, such that they get deleted automatically when not used anymore.

Definition at line 371 of file matrix_block.h.

Member Function Documentation

◆ add()

template<typename MatrixType >
void MatrixBlockVector< 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.

Definition at line 849 of file matrix_block.h.

◆ reinit()

template<typename MatrixType >
void MatrixBlockVector< MatrixType >::reinit ( const BlockSparsityPattern sparsity)
inline

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

Definition at line 860 of file matrix_block.h.

◆ clear()

template<typename MatrixType >
void MatrixBlockVector< 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.

Definition at line 871 of file matrix_block.h.

◆ memory_consumption()

template<typename MatrixType >
std::size_t MatrixBlockVector< MatrixType >::memory_consumption ( ) const

The memory used by this object.

◆ block() [1/2]

template<typename MatrixType >
const MatrixBlock< MatrixType > & MatrixBlockVector< MatrixType >::block ( size_type  i) const
inline

Access a constant reference to the block at position i.

Definition at line 888 of file matrix_block.h.

◆ block() [2/2]

template<typename MatrixType >
MatrixBlock< MatrixType > & MatrixBlockVector< MatrixType >::block ( size_type  i)
inline

Access a reference to the block at position i.

Definition at line 896 of file matrix_block.h.

◆ matrix()

template<typename MatrixType >
MatrixType & MatrixBlockVector< MatrixType >::matrix ( size_type  i)
inline

Access the matrix at position i for read and write access.

Definition at line 904 of file matrix_block.h.

◆ name()

template<typename MatrixType >
const std::string & AnyData::name
inline

import functions from private base class

Definition at line 311 of file any_data.h.

◆ size()

template<typename MatrixType >
unsigned int AnyData::size
inline

Number of stored data objects.

Definition at line 223 of file any_data.h.
