template<class GridPartImp , class IntegrationTraits >

GeometryType Dune::Fem::ElementPointListBase< GridPartImp, 0, IntegrationTraits >::elementGeometry ( ) const

inlineinherited

obtain GeometryType of the corresponding codim-0 the integration point list belongs to

An element integration point list can return the coordinates of integration points with resepct to the codim-0 reference element and the reference element corresponding to the subentity the quadrature actually lives on. This method returns the geometry of the codim-0 entity.

Note: Calling this method yields a virtual function call, so do not call this method unnecessarily.

Returns: GeometryType for this integration point list

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

obtain local coordinates of i-th integration point

This method returns a reference to the local coordinates of the i-th integration point for 0 <= i < nop(). Here, local coordinates means coordinates with respect to the reference element of the subentity.

Parameters

[in] i number of the integration point, 0 <= i < nop()

Returns: reference to i-th integration point

◆ order()

template<class GridPartImp , class IntegrationTraits >

int Dune::Fem::ElementPointListBase< GridPartImp, 0, IntegrationTraits >::order ( ) const

inlineinherited

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.

Note: Calling this method yields a virtual function call, so do not call this method unnecessarily.

Returns: the order of the integration point list

obtain weight of i-th integration point (if quadrature, else 1.0)

This method returns the weight of the i-th integration point for 0 <= i < nop() within the quadrature.

Note: The integration point can be obtained via the point() method.; The quadrature weights sum up to the volume of the reference element.
