Detailed Description

template<typename GV, template< int > class LayoutClass = Impl::MCMGFailLayout>
class Dune::MultipleCodimMultipleGeomTypeMapper< GV, LayoutClass >

Implementation class for a multiple codim and multiple geometry type mapper.

In this implementation of a mapper the entity set used as domain for the map consists of the entities of a subset of codimensions in the given index set. The index set may contain entities of several geometry types. This version is usually not used directly but is used to implement versions for leafwise and levelwise entity sets.

The geometry types to be included in the mapper are selected using a layout functional (MCMGLayout) that is passed to the constructor.

Template Parameters

GV A Dune GridView type.

LayoutClass

(deprecated) A helper class template with a method contains(), that returns true for all geometry types that are in the domain of the map. The class should be of the following shape

template<int dimgrid>
struct LayoutClass {
bool contains (Dune::GeometryType gt) const {
   // Return true if gt is in the domain of the map
}
};

The MultipleCodimMultipleGeomTypeMapper will always substitute the dimension of the grid for the template parameter dimgrid.

Member Typedef Documentation

◆ size_type

template<typename GV , template< int > class LayoutClass = Impl::MCMGFailLayout>

using Dune::MultipleCodimMultipleGeomTypeMapper< GV, LayoutClass >::size_type = decltype(std::declval<typename GV::IndexSet>().size(0))

Number type used for the overall size (the return value of the 'size' method)

The type used here is set to be the corresponding type used by the GridView's index set.

◆ MultipleCodimMultipleGeomTypeMapper() [1/2]

template<typename GV , template< int > class LayoutClass = Impl::MCMGFailLayout>

Dune::MultipleCodimMultipleGeomTypeMapper< GV, LayoutClass >::MultipleCodimMultipleGeomTypeMapper	(	const GV &	gridView,
		const LayoutClass< GV::dimension >	layout = `{}`
	)

inline

Construct mapper from grid and one of its index sets.

Parameters

gridView	A Dune GridView object.
layout	A layout object.

Deprecated:: Use the constructor taking a MCMGLayout instead.

Deprecated:: "Use the constructor taking a `MCMGLayout` functional instead"

template<typename GV , template< int > class LayoutClass = Impl::MCMGFailLayout>

Dune::MultipleCodimMultipleGeomTypeMapper< GV, LayoutClass >::MultipleCodimMultipleGeomTypeMapper	(	const GV &	gridView,
		const MCMGLayout &	layout
	)

inline

construct mapper from grid and layout description

The layout parameter is a functional describing entities of which geometry types are included in the mapper. For commonly used cases, convenience functions are provided. See the MCMGLayout type documentation for details.

Parameters

gridView	grid view whose entities should be included in the mapper
layout	functional describing how many dof to store on each entity (fixed per geometry type)

template<typename GV , template< int > class LayoutClass = Impl::MCMGFailLayout>

template<class EntityType >

IntegralRange< Index > Dune::MultipleCodimMultipleGeomTypeMapper< GV, LayoutClass >::indices ( const EntityType & e ) const

inline

Returns a pair with the starting point in the dof vector and the number of degrees of freedom if the entity is contained in the index set otherwise {0,0} is returned.

Parameters

e	Reference to entity
result	integer reference to the start of the block

Returns: pair with first entry equal to index for that entity and the second entry the number of degrees of freedom (zero if entity is not in entity set of the mapper)
