Detailed Description

template<class IMS, class... SPB>
class Dune::Functions::CompositePreBasis< IMS, SPB >

A pre-basis for composite bases.

This pre-basis represents a composition of several given pre-bases. Its node type is a CompositeBasisNodes for the given subnodes.

Template Parameters

IMS	An IndexMergingStrategy used to merge the global indices of the child pre-bases
SPB	The child pre-bases

Dune::Functions::CompositePreBasis< IMS, SPB >::CompositePreBasis ( SFArgs &&...  sfArgs )

inline

Constructor for given child pre-basis objects.

The child pre-basis will be stored as copies

template<class IMS , class... SPB>

template<class GV , std::enable_if_t< std::conjunction_v< std::bool_constant<(children > 1)>, std::is_same< GV, GridView >, std::is_constructible< SPB, GridView >... > , int >

Dune::Functions::CompositePreBasis< IMS, SPB >::CompositePreBasis ( const GV &  gv )

inline

Constructor for given GridView.

This constructor is only available if all child pre-bases are constructible from the grid view.
