Detailed Description

template<int dim, int fe_degree, int n_q_points_1d, int n_components, typename Number>
struct SelectEvaluator< dim, fe_degree, n_q_points_1d, n_components, Number >

This class chooses an appropriate evaluation strategy based on the template parameters and the shape_info variable which contains runtime parameters. In case the template parameters fe_degree and n_q_points_1d contain valid information (i.e. fe_degree>-1 and n_q_points_1d>0), we simply pass these values to the respective template specializations. Otherwise, we perform a runtime matching of the runtime parameters to find the correct specialization. This matching currently supports \(0\leq fe\_degree \leq 9\) and \(degree+1\leq n\_q\_points\_1d\leq fe\_degree+2\).

Member Function Documentation

evaluate()

template<int dim, int fe_degree, int n_q_points_1d, int n_components, typename Number>

static void SelectEvaluator< dim, fe_degree, n_q_points_1d, n_components, Number >::evaluate ( const internal::MatrixFreeFunctions::ShapeInfo< Number > &  shape_info, Number *  values_dofs_actual, Number *  values_quad, Number *  gradients_quad, Number *  hessians_quad, Number *  scratch_data, const bool  evaluate_values, const bool  evaluate_gradients, const bool  evaluate_hessians  )

static

Chooses an appropriate evaluation strategy for the evaluate function, i.e. this calls internal::FEEvaluationImpl::evaluate(), internal::FEEvaluationImplCollocation::evaluate() or internal::FEEvaluationImplTransformToCollocation::evaluate() with appropriate template parameters.

integrate()

template<int dim, int fe_degree, int n_q_points_1d, int n_components, typename Number>

static void SelectEvaluator< dim, fe_degree, n_q_points_1d, n_components, Number >::integrate ( const internal::MatrixFreeFunctions::ShapeInfo< Number > &  shape_info, Number *  values_dofs_actual, Number *  values_quad, Number *  gradients_quad, Number *  scratch_data, const bool  integrate_values, const bool  integrate_gradients  )

static

Chooses an appropriate evaluation strategy for the integrate function, i.e. this calls internal::FEEvaluationImpl::integrate(), internal::FEEvaluationImplCollocation::integrate() or internal::FEEvaluationImplTransformToCollocation::integrate() with appropriate template parameters.
