Detailed Description

template<class G, class IndexSet, class Vector>
class Dune::PersistentContainerVector< G, IndexSet, Vector >

vector-based implementation of the PersistentContainer

Some grid implementations, like YaspGrid, can provide consecutive, zero-based, persistent indices for the entire grid hierarchy. This implementation of a PersistentContainer uses such an index set and a std::vector-like container to store user data in an efficient and persistent manner.

Note

The persistent index set is actually allowed to be non-consecutive, i.e., some indices might not be assigned to an entity. As the result of the size method on the index set is used to allocate storage for the vector, it must be larger than the largest used index.

It is sufficient if the index set provides indices to the codimension the persistent container is created for. Neither the method types() nor the method contains() need to be implemented.

The persistent container is currently restricted to index sets containing a single geometry type.

Todo:

Actually, we use a mapper rather than an index set. This would automatically resolve two problems:

• support multiple geometry types,
• the requirement to store a reference to the index set .

Template Parameters

G	type of grid
IndexSet	type of persistent index set
Vector	type of vector to store the data in
