Detailed Description

template<class FunctionSpaceTraits>
class Dune::Fem::DiscreteFunctionSpaceInterface< FunctionSpaceTraits >

This is the interface for discrete function spaces. All methods declared here have to be implemented by the implementation class.

The discrete function space always depends on a given grid. For all diffrent element types of the grid the function space provides a set of base functions for the different element types. Because of the knowledge of on the one hand the grid an on the other hand the base functions sets, the discrete function space provides the size of the function space and a mapping from entity and local dof number to global dof number of the level of the entity.

Note
A DiscreteFunctionSpace is defined on a certain grid part.
An interface class:
