class Dune::Fem::CachingQuadrature< GridPartImp, codim, QuadratureTraits >

quadrature class supporting base function caching

A CachingQuadrature is a conceptual extension to the ElementQuadrature. It provides an additional mapping from local quadrature point numbers on a subentity's reference element to global quadrature point numbers on the codim-0 reference element. Consider, for instance, a quadrature for one of the faces of a tetrahedron: It provides n local quadrature points, which can lie on one of the four faces, resulting in 4*n global quadrature points.

The information from the mapping can be used to cache a base function on those global quadrature points.

Note

If you don't want caching, you can use ElementQuadrature instead.

QuadratureTraits specifies the quadrature points used to build the quadrature.
