Detailed Description

template<typename number = double, typename BlockVectorType = BlockVector<number>>
class BlockMatrixArray< number, BlockVectorType >::Entry

Internal data structure.

For each entry of a BlockMatrixArray, its position, matrix, prefix and optional transposition must be stored. This structure encapsulates all of them.

Constructor & Destructor Documentation

Entry() [1/2]

template<typename number = double, typename BlockVectorType = BlockVector<number>>

template<typename MatrixType >

BlockMatrixArray< number, BlockVectorType >::Entry::Entry	(	const MatrixType &	matrix,
		size_type	row,
		size_type	col,
		number	prefix,
		bool	transpose
	)

Constructor initializing all data fields. A PointerMatrix object is generated for matrix.

Entry() [2/2]

template<typename number , typename BlockVectorType >

BlockMatrixArray< number, BlockVectorType >::Entry::Entry

(

const Entry &

e

)

Copy constructor invalidating the old object. Since it is only used for entering temporary objects into a vector, this is ok.

For a deep copy, we would need a reproduction operator in PointerMatixBase.

~Entry()

template<typename number , typename BlockVectorType >

BlockMatrixArray< number, BlockVectorType >::Entry::~Entry

(

)

Destructor, where we delete the PointerMatrix created by the constructor.

Member Function Documentation

operator=()

template<typename number = double, typename BlockVectorType = BlockVector<number>>

Entry& BlockMatrixArray< number, BlockVectorType >::Entry::operator= ( const Entry &  )

delete

Assignment operator.

Note

Since the copy constructor is destructive (see its documentation) and only exists for convenience there is no reasonable way to implement this, so it is explicitly deleted.
