Implementation class for a multiple codim and multiple geometry type mapper.
In this implementation of a mapper the entity set used as domain for the map consists of the entities of a subset of codimensions in the given index set. The index set may contain entities of several geometry types. This version is usually not used directly but is used to implement versions for leafwise and levelwise entity sets.
The geometry types to be included in the mapper are selected using a layout functional (MCMGLayout) that is passed to the constructor.
GV | A Dune GridView type. |
LayoutClass | (deprecated) A helper class template with a method contains(), that returns true for all geometry types that are in the domain of the map. The class should be of the following shape template<int dimgrid> struct LayoutClass { // Return true if gt is in the domain of the map } }; |
typedef GV Dune::MultipleCodimMultipleGeomTypeMapper< GV, LayoutClass >::GridView |
Underlying GridView.
typedef GV::IndexSet::IndexType Dune::MultipleCodimMultipleGeomTypeMapper< GV, LayoutClass >::Index |
Number type used for indices.
using Dune::MultipleCodimMultipleGeomTypeMapper< GV, LayoutClass >::size_type = decltype(std::declval<typename GV::IndexSet>().size(0)) |
Number type used for the overall size (the return value of the 'size' method)
The type used here is set to be the corresponding type used by the GridView's index set.

construct mapper from grid and layout description
The layout
parameter is a functional describing entities of which geometry types are included in the mapper. For commonly used cases, convenience functions are provided. See the MCMGLayout type documentation for details.
gridView | grid view whose entities should be included in the mapper |
layout | functional describing how many dof to store on each entity (fixed per geometry type) |
|

[in] | e | Reference to entity |
[out] | result | Filled with array index if entity is contained |
|

Returns true if the subentity is contained in the index set and at the same time the array index is returned.

inline |
Return total number of entities in the entity set managed by the mapper.
This number can be used to allocate a vector of data elements associated with the entities of the set. In the parallel case this number is per process (i.e. it may be different in different processes).
|
inline |
return number of entries for a given geometry type
|
inlineinherited |
Map subentity i of codim cc of a codim 0 entity to array index.
e | Reference to codim 0 entity. |
i | Number of codim cc subentity of e, where cc is the template parameter of the function. |
codim | codimension of subentity of e |
|
inline |
Map subentity of codim 0 entity to starting index in array for dof block.
e | Reference to codim 0 entity. |
i | Number of subentity of e |
codim | Codimension of the subentity |
