Detailed Description

template<int dimension, unsigned int topologyId>
struct Dune::PDELab::BasicTypeFromDimensionAndTopologyId< dimension, topologyId >

Utility TMP for determining the BasicType of a geometry from its dimension and topology id.

BasicTypeFromDimensionAndTopologyId invokes GenericGeometry-internal machinery to identify the GeometryType::BasicType that belongs to the given combination of dimension and topologyId.

This information is often useful when writing generic frontends for FiniteElementMaps that are specialized on dimension and BasicType.

Template Parameters

dimension	The dimension of the geometry.
topologyId	The topologyId of the geometry.
