Detailed Description
class Dune::Fem::IntegrationPointList< FieldImp, dim, IntegrationTraits, isQuadrature >
actual interface class for integration point lists
IntegrationPointList is a proxy for the actual implementations of the integration point lists. During construction, the IntegrationPointList object is configured with an appropriate implementation object from the QuadratureProvider (monostate pattern).
The design goal is minimization of construction time. The actual implementation can be created once and reused whenever it is needed. Moreover, this layout insulates the user from all initialization and storage stuff.
- Note
- The difference between integration point lists and quadratures is that quadratures have weights.

Member Function Documentation
◆ geometryType()
|
inline |
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.
- Note
- Calling this method yields a virtual function call, so do not call this method unnecessarily.
- Returns
- GeometryType for this integration point list
References Dune::Fem::IntegrationPointList< FieldImp, dim, IntegrationTraits, isQuadrature >::ipList().
◆ id()
|
inline |
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
References Dune::Fem::IntegrationPointList< FieldImp, dim, IntegrationTraits, isQuadrature >::ipList().
◆ ipList()
|
inline |
obtain a reference the actual implementation
- Returns
- a reference to the implementation of this integration point list

◆ nop()
|
inline |
obtain the number of integration points
- Returns
- number of integration points within this list

◆ order()
|
inline |
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
References Dune::Fem::IntegrationPointList< FieldImp, dim, IntegrationTraits, isQuadrature >::ipList().
◆ point()
|
inline |
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] i number of the integration point, 0 <= i < nop()
- Returns
- reference to i-th integration point
References Dune::Fem::IntegrationPointList< FieldImp, dim, IntegrationTraits, isQuadrature >::ipList().
◆ weight()
|
inline |
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.
- Parameters
-
[in] i number of the integration point, 0 <= i < nop()
- Returns
- weight of the i-th integration point
