bool Dune::PDELab::MatrixExchangeDataHandle< GFS, M >::contains ( int  dim, int  codim  ) const

inline

returns true if data for this codim should be communicated

fixedSize()

template<class GFS , class M >

bool Dune::PDELab::MatrixExchangeDataHandle< GFS, M >::fixedSize ( int  dim, int  codim  ) const

inline

returns true if size per entity of given dim and codim is a constant

template<class EntityType >

size_t Dune::PDELab::MatrixExchangeDataHandle< GFS, M >::size ( EntityType &  e ) const

inline
