Detailed Description
template<typename ct, int dim>
class Dune::QuadratureRule< ct, dim >
class Dune::QuadratureRule< ct, dim >
Abstract base class for quadrature rules.
Contains a list of QuadraturePoint used to integrate numerically a function with a domain given by the a GeometryType.
Usage:
QuadratureRule<ct,dim> quadrature = Dune::QuadratureRules<ct,dim>::rule(...); // obtain a quadrature rule
double integral = 0.;
for(auto [position, weight] : quadrature) // iterate over quadrature points
integral += f(position) * weight; // accumulate weighted results
static const QuadratureRule & rule(const GeometryType &t, int p, QuadratureType::Enum qt=QuadratureType::GaussLegendre)
select the appropriate QuadratureRule for GeometryType t and order p

Member Typedef Documentation
◆ iterator
template<typename ct , int dim>
typedef std::vector<QuadraturePoint<ct,dim>>::const_iterator Dune::QuadratureRule< ct, dim >::iterator |
this container is always a const container, therefore iterator is the same as const_iterator

inline |
Default constructor.
Create an invalid empty quadrature rule. This must be initialized later by copying another quadraturerule before it can be used.
