Detailed Description

template<int n_matrices = 1, int n_vectors = n_matrices, int n_dof_indices = n_matrices>
struct MeshWorker::CopyData< n_matrices, n_vectors, n_dof_indices >

Helper copy data struct.

This class is a good default drop in CopyData object for the WorkStream::run() and MeshWorker::mesh_loop() functions.

It arrays of (local) full matrices, vectors, and local degrees of freedom index vectors, with size determined by the corresponding template argument.

In particular, you can specify the following template arguments

• Template Parameters

  n_matrices

  Size of the array of matrices

• Template Parameters

  n_vectors

  size of the array of vectors

• Template Parameters

  n_dof_indices

  size of the array of local dof indices

Constructor & Destructor Documentation

CopyData() [1/3]

template<int n_matrices = 1, int n_vectors = n_matrices, int n_dof_indices = n_matrices>

MeshWorker::CopyData< n_matrices, n_vectors, n_dof_indices >::CopyData

(

const unsigned int

size

)

Initialize everything with the same size. This is usually the number of local degrees of freedom.

CopyData() [2/3]

template<int n_matrices = 1, int n_vectors = n_matrices, int n_dof_indices = n_matrices>

MeshWorker::CopyData< n_matrices, n_vectors, n_dof_indices >::CopyData	(	const std::array< std::array< unsigned int, 2 >, n_matrices > &	matrix_sizes,
		const std::array< unsigned int, n_vectors > &	vector_sizes,
		const std::array< unsigned int, n_dof_indices > &	dof_indices_sizes
	)

For every object, specify the size they should have.

CopyData() [3/3]

template<int n_matrices = 1, int n_vectors = n_matrices, int n_dof_indices = n_matrices>

MeshWorker::CopyData< n_matrices, n_vectors, n_dof_indices >::CopyData ( const CopyData< n_matrices, n_vectors, n_dof_indices > &  other )

default

Deep copy constructor.

Member Function Documentation

operator=()

(

const double &

number

)

Allow resetting of all elements of the struct to zero, by simply calling (*this) = 0;

Notice that the only allowed number here is really 0. Calling this function with any other number will trigger an assertion.

The elements of the arrays of local degrees of freedom indices are all set to numbers::invalid_dof_index.
