Detailed Description

template<class GridView>
class Dune::Functions::SubEntityDOFs< GridView >

Range of DOFs associated to sub-entity.

This provides a range of DOFs associated to a given sub-entity by its LocalKeys. In order to use this, it has to be bound to a bound LocalView and a sub-entity. The latter is either encoded by its local index and codimension wrt the element the LocalView is bound to, or by an intersection having this element as inside.

After beeing bound this class can be used as range of local indices of those DOFs that are associated to the sub-entity or sub-sub-entities of this sub-entity. Furthermore it allows to ask if a given local index is contained in this range.

Notice that the class itself does only depend on the GridView because it needs to allocate some dimension-dependent containers for caching the information computed during bind.

Template Parameters

GridView

The GridView LocalViews should act on

SubEntityDOFs & Dune::Functions::SubEntityDOFs< GridView >::bind ( const LocalView &  localView, const Intersection &  intersection  )

inline

Bind SubEntityDOFs object to LocalView and sub-entity.

Notice that this method will pre-compute and cache the contained local indices as well as a look-up table for checking if a local index is contained. The sub-entity is encoded as intersection having localView.element() as inside. This is equivalent to bind(localView, intersection.indexInInside(),1), In order to be able to bind and use the range in a single expression this returns *this for convenience.

Parameters

localView	A bound LocalView to bind to
intersection	An Intersection encoding the sub-entity to bind to

Returns

*this for convenience

template<class LocalView >

SubEntityDOFs & Dune::Functions::SubEntityDOFs< GridView >::bind ( const LocalView &  localView, std::size_t  subEntityIndex, std::size_t  subEntityCodim  )

inline

Bind SubEntityDOFs object to LocalView and sub-entity.

Notice that this method will pre-compute and cache the contained local indices as well as a look-up table for checking if a local index is contained. The sub-entity is encoded as (index,codim) with respect to the element the LocalView is bound to. In order to be able to bind and use the range in a single expression this returns *this for convenience.

Parameters

localView	A bound LocalView to bind to
subEntityIndex	Index of sub-entity in localView.element()
subEntityCodim	Codimension of sub-entity in localView.element()

Returns

*this for convenience
