A Vector of blocks with different blocksizes.
This class started as a copy of VariableBlockVector, which used to be used for the internal memory managerment of the 'Matrix' class. However, that mechanism stopped working when I started using the RandomAccessIteratorFacade in VariableBlockVector (308dd85483108f8baaa4051251e2c75e2a9aed32, to make VariableBlockVector pass a number of tightened interface compliance tests), and I couldn't quite figure out how to fix that. However, using VariableBlockVector in Matrix internally was a hack anyway, so I simply took the working version of VariableBlockVector and copied it here under the new name of DenseMatrixBase. This is still hacky, but one step closer to an elegant solution.
typedef A Dune::MatrixImp::DenseMatrixBase< B, A >::allocator_type |
export the allocator type
typedef BlockVector<B,A> Dune::MatrixImp::DenseMatrixBase< B, A >::block_type |
Same as value_type, here for historical reasons.
using Dune::MatrixImp::DenseMatrixBase< B, A >::const_iterator = ConstIterator |
Export the const iterator type using std naming rules.
typedef const window_type Dune::MatrixImp::DenseMatrixBase< B, A >::const_reference |
using Dune::MatrixImp::DenseMatrixBase< B, A >::field_type = typename Imp::BlockTraits<B>::field_type |
export the type representing the field
using Dune::MatrixImp::DenseMatrixBase< B, A >::iterator = Iterator |
Export the iterator type using std naming rules.
typedef window_type Dune::MatrixImp::DenseMatrixBase< B, A >::reference |
typedef A::size_type Dune::MatrixImp::DenseMatrixBase< B, A >::size_type |
The size type for the index access.
typedef BlockVector<B,A> Dune::MatrixImp::DenseMatrixBase< B, A >::value_type |
Type of the elements of the outer vector, i.e., dynamic vectors of B.
Note that this is not the type referred to by the iterators and random access operators, which return proxy objects.
