Detailed Description

template<class BlockMatrix>
class BlockMatrixIterators::Accessor< BlockMatrix, true >

Block matrix accessor for constant matrices, implementing the stepping through a matrix.

Member Typedef Documentation

template<class BlockMatrix >
typedef const BlockMatrix BlockMatrixIterators::Accessor< BlockMatrix, true >::MatrixType

Thype of the matrix used in this accessor.

template<class BlockMatrix >
typedef BlockMatrix::value_type BlockMatrixIterators::Accessor< BlockMatrix, true >::value_type

Typedef the value type of the matrix we point into.

Reimplemented from BlockMatrixIterators::AccessorBase< BlockMatrix >.


Constructor & Destructor Documentation

template<class BlockMatrix >
BlockMatrixIterators::Accessor< BlockMatrix, true >::Accessor ( const BlockMatrix *  m,
const unsigned int  row,
const unsigned int  col 
)

Constructor. Since we use accessors only for read access, a const matrix pointer is sufficient.

Place the iterator at the beginning of the given row of the matrix, or create the end pointer if row equals the total number of rows in the matrix.

template<class BlockMatrix >
BlockMatrixIterators::Accessor< BlockMatrix, true >::Accessor ( const Accessor< BlockMatrix, false > &   ) 

Initalize const accessor from non const accessor.


Member Function Documentation

template<class BlockMatrix >
unsigned int BlockMatrixIterators::Accessor< BlockMatrix, true >::row (  )  const

Row number of the element represented by this object.

template<class BlockMatrix >
unsigned int BlockMatrixIterators::Accessor< BlockMatrix, true >::column (  )  const

Column number of the element represented by this object.

template<class BlockMatrix >
value_type BlockMatrixIterators::Accessor< BlockMatrix, true >::value (  )  const

Value of the entry at the current position.

template<class BlockMatrix >
void BlockMatrixIterators::Accessor< BlockMatrix, true >::advance (  )  [protected]

Move ahead one element.

template<class BlockMatrix >
bool BlockMatrixIterators::Accessor< BlockMatrix, true >::operator== ( const Accessor< BlockMatrix, true > &  a  )  const [protected]

Compare this accessor with another one for equality.


Friends And Related Function Documentation
