Detailed Description

template<typename SpaceType>
class Feel::TwoSpacesMap< SpaceType >

This class provides a correspondancy map between two spaces and particularly between a sequential space Xs defined on a submesh of the parallel space Xp.

For any dof in Xs the class provides the index which has the corresponding dof in parallel and the index of this dof in Xp.
