Detailed Description

template<class FieldImp, int dim, unsigned int maxPolOrder>
class Dune::Fem::LagrangePointListInterface< FieldImp, dim, maxPolOrder >

Set of lagrange points.

Interface class for a set of lagrange points. An instance of the lagrange points can be obtained from the lagrange function space. The set can be wrapped in a quadrature.

Member Function Documentation

◆ addIntegrationPoint()

template<typename FieldImp , int dim>
void Dune::Fem::IntegrationPointListImp< FieldImp, dim >::addIntegrationPoint ( const CoordinateType point)
inlineprotectedinherited

Adds an integration point to the list.

This method allows derived classes to add integration points to the list. This mehtod should only be used within the constructor of the derived class.

References Dune::Fem::IntegrationPointListImp< FieldImp, dim >::point().

◆ geometryType()

template<class FieldImp , int dim, unsigned int maxPolOrder>
GeometryType Dune::Fem::LagrangePointListInterface< FieldImp, dim, maxPolOrder >::geometryType ( ) const
inlinevirtual

obtain GeometryType for this integration point list

Integration point lists are specified in local coordinates, i.e., coordinates with respect to the reference element. Hence, each integration point list is only valid for one type of geometry, i.e., for one reference element. The type can be retrieved via this method.

Returns
GeometryType for this integration point list

Implements Dune::Fem::IntegrationPointListImp< FieldImp, dim >.

◆ id()

template<typename FieldImp , int dim>
size_t Dune::Fem::IntegrationPointListImp< FieldImp, dim >::id ( ) const
inlineinherited

obtain the identifier of the integration point list

The identifier of an integration point list must be globally unique. Even integration point lists for different dimensions must have different identifiers.

Note
Quadratures are considered distinct if they differ in one of the following points: geometry type, order, dimension or implementation.
Returns
globally unique identifier of the integration point list

◆ maxDofs()

template<class FieldImp , int dim, unsigned int maxPolOrder>
unsigned int Dune::Fem::LagrangePointListInterface< FieldImp, dim, maxPolOrder >::maxDofs ( unsigned int  codim) const
inline

obtain the maximal number of DoFs in one entity of a codimension

Parameters
[in]codimcodimension, the information is desired for
Returns
maximal number of DoFs for one entity in the codimension

◆ nop()

template<typename FieldImp , int dim>
size_t Dune::Fem::IntegrationPointListImp< FieldImp, dim >::nop ( ) const
inlineinherited

obtain the number of integration points

Returns
number of integration points within this list

Referenced by Dune::Fem::IntegrationPointListImp< FieldImp, dim >::point().

◆ numDofs() [1/2]

template<class FieldImp , int dim, unsigned int maxPolOrder>
unsigned int Dune::Fem::LagrangePointListInterface< FieldImp, dim, maxPolOrder >::numDofs ( unsigned int  codim) const
inline

obtain the total number of DoFs in a codimension

Parameters
[in]codimcodimension the information is desired for
Returns
the number of DoFs associated with the codimension

◆ numDofs() [2/2]

template<class FieldImp , int dim, unsigned int maxPolOrder>
unsigned int Dune::Fem::LagrangePointListInterface< FieldImp, dim, maxPolOrder >::numDofs ( unsigned int  codim,
unsigned int  subEntity 
) const
inline

obtain the number of DoFs on one entity

Parameters
[in]codimcodimension of the entity
[in]subEntitynumber of the subentity (of the given codimension)
Returns
the number of DoFs associated with the specified entity

◆ order()

template<class FieldImp , int dim, unsigned int maxPolOrder>
int Dune::Fem::LagrangePointListInterface< FieldImp, dim, maxPolOrder >::order ( ) const
inlinevirtual

obtain order of the integration point list

The order of a quadrature is the maximal polynomial degree that is guaranteed to be integrated exactly by the quadrature.

In case of an integration point list, the definition of this value is left to the implementor.

Returns
the order of the integration point list

Implements Dune::Fem::IntegrationPointListImp< FieldImp, dim >.

◆ point()

template<typename FieldImp , int dim>
const CoordinateType & Dune::Fem::IntegrationPointListImp< FieldImp, dim >::point ( size_t  i) const
inlineinherited

obtain coordinates of i-th integration point

This method returns a reference to the coordinates of the i-th integration point for 0 <= i < nop(). The integration point is given in local coordinates, i.e., coordinates with respect to the reference element.

Parameters
[in]inumber of the integration point, 0 <= i < nop()
Returns
reference to i-th integration point
