Dune::RefinementImp::Traits< topologyId, CoordType, coerceToId, dimension, Dummy > Struct Template Reference

Detailed Description

template<unsigned topologyId, class CoordType, unsigned coerceToId, int dimension, class Dummy = void>
struct Dune::RefinementImp::Traits< topologyId, CoordType, coerceToId, dimension, Dummy >

Mapping from geometryType, CoordType and coerceTo to a particular Refinement implementation.

Template Parameters

topologyId	The topology id of the element to refine
CoordType	The C++ type of the coordinates
coerceToId	The topologyId of the subelements
dimension	The dimension of the refinement.
Dummy	Dummy parameter which can be used for SFINAE, should always be void.

Each Refinement implementation has to define one or more specialisations of this struct to declare what it implements. Template class Refinement uses this struct to know which implementation it should inherit from. Since non-type template arguments of specializations may not involve template parameters, it is often impossible to specify the specialization for all cases directly. As the workaround, the template parameter Dummy can be used for SFINAE with enable_if.

Each specialisation should contain a single member typedef Imp, e.g.:

template<class CoordType>
struct Traits<sphereTopologyId, CoordType, Impl::CubeToplogy<2>::id, 2>
{
  typedef SquaringTheCircle::Refinement Imp;
};
