Detailed Description

template<typename GV>
class Dune::Functions::LeafPreBasisMapperMixin< GV >

A generic MixIn class for PreBasis with flat indices computed from a mapper.

This abstracts all index computations that can be implemented using a MultipleCodimMultipleGeomTypeMapper with appropriate MCMGLayout. In order to use this, you need to derive from this class and pass the layout in the constructor. Then the mixin takes care for all the index and size computation and the derived class only needs to add the node creation.

Be careful: This does not do any reordering of indices if multiple basis functions are associated to the same subentity.

Template Parameters
GVThe grid view the basis is defined on.
