IBTK::FEMappingCache< dim, spacedim > Class Template Reference

Class storing multiple IBTK::FEMapping objects. We assume that quadrature rules are uniquely determined by the element type, quadrature type, and approximation order. There are several places in IBTK where we make this assumption, e.g., we will use data from two quadrature rules assumed to be equal (by this metric) to initialize different libMesh objects. More...

Detailed Description

template<int dim, int spacedim = dim>
class IBTK::FEMappingCache< dim, spacedim >

This class essentially provides a wrapper around std::map to manage IBTK::FEMapping (and classes inheriting from it) objects.

Member Typedef Documentation

key_type

template<int dim, int spacedim = dim>

using IBTK::FEMappingCache< dim, spacedim >::key_type = quadrature_key_type

Key type. Completely describes (excepting p-refinement) a libMesh quadrature rule.

value_type

template<int dim, int spacedim = dim>

using IBTK::FEMappingCache< dim, spacedim >::value_type = FEMapping<dim, spacedim>

Type of values stored by this class that are accessible through operator[].
