IBTK::QuadratureCache Class Reference

Class storing multiple libMesh quadrature 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 FEMap objects. More...

Detailed Description

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

Member Typedef Documentation

key_type

using IBTK::QuadratureCache::key_type = quadrature_key_type

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

value_type

using IBTK::QuadratureCache::value_type = libMesh::QBase

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

Constructor & Destructor Documentation

QuadratureCache()

IBTK::QuadratureCache::QuadratureCache ( unsigned int  dim )

inline

Constructor. Sets up a cache of Quadrature objects.

Parameters

dim	The topological dimension of the relevant libMesh::Mesh: see libMesh::MeshBase::mesh_dimension() for more information.

Member Function Documentation

operator[]()

QuadratureCache::value_type & IBTK::QuadratureCache::operator[] ( const key_type &  quad_key )

inline

Return a reference to a Quadrature object that matches the specified quadrature rule type and order.

Parameters

quad_key

a tuple of enums that completely describes a libMesh quadrature rule.

clear()

void IBTK::QuadratureCache::clear ( )

inline

Clear the cache.
