Detailed Description

template<int dim, int spacedim = dim>
class MeshWorker::InfoObjects::DoFInfo< dim, spacedim >

Very basic info class only containing information on geometry and degrees of freedom of a mesh entity.

The information in this class is usually used by one of the Assembler classes. This information is also needed in mesh based matrices (often referred to as matrix free methods).

This class operates in two different modes, corresponding to the data models discussed in the Assembler namespace documentation.

The choice of the local data model is triggered by the vector #BlockInfo::local_renumbering, which in turn is usually filled by #BlockInfo::initialize_local(). If this function has been called, or if this vector has been changed from zero-length, then local dof indices stored in this class will automatically be renumbered to reflect the local block structure.

The BlockInfo object is stored here as a pointer. Therefore, if the local block structure changes, for instance because of the mesh refinement, the DoFInfo class will automatically use this new structure.
