Detailed Description

template<class GridImp, class MapperType, class DofArrayType>
class Dune::Fem::ManagedDofStorageImplementation< GridImp, MapperType, DofArrayType >

A ManagedDofStorage holds the memory for one DiscreteFunction and the corresponding DofArrayMemory. ManagedDofStorageImplementation implements the basic features such as resize and dof compression. If a DiscreteFunction is signed in by a function space, then such a MemObject is created by the DofManager. The MemObject also knows the DofMapper from the function space which the discrete function belongs to. Here we dont know the exact type of the dof mapper therefore the methods newSize and calcInsertPoints of the mappers have to be virtual. This isnt a problem because this methods should only be called during memory reorganizing which is only once per timestep.
