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.
