Constructor & Destructor Documentation

DOFVector() [1/3]

DOFVector ( std::shared_ptr< GB > const &  basis, DataTransferTag  = {}  )

inline

(1) Constructor. Stores the shared_ptr of the basis and creates a new DataTransfer.

DOFVector() [2/3]

DOFVector ( GB_ &&  basis, DataTransferTag  tag = {}  )

inline

(2) Constructor. Forwards to (1) by wrapping reference into non-destroying shared_ptr, see Dune::wrap_or_move.

DOFVector() [3/3]

DOFVector ( GV const &  gridView, PBF const &  preBasisFactory, DataTransferTag  tag = {}  )

inline

(3) Constructor. Forwards to (1) by creating a new basis from a dune-functions pre-basis factory.

Member Function Documentation

updateImpl() [1/3]

void updateImpl ( event::adapt  e )

inlineoverrideprotected

Override of Observer update(event::adapt) method. Redirects to adapt method of the DataTransfer object.

updateImpl() [2/3]

void updateImpl ( event::postAdapt  )

inlineoverrideprotected

Override of Observer update(event::postAdapt) method. Redirects to postAdapt method of the DataTransfer object.

updateImpl() [3/3]

void updateImpl ( event::preAdapt  e )

inlineoverrideprotected
