Store the indices of the degrees of freedom which are located on objects of dimension dim.
The DoFObjects classes store the global indices of the degrees of freedom for each cell on a certain level. The global index or number of a degree of freedom is the zero-based index of the according value in the solution vector and the row and column index in the global matrix or the multigrid matrix for this level. These indices refer to the unconstrained vectors and matrices, where we have not taken account of the constraints introduced by hanging nodes.
Since vertices are not associated with a particular level, the indices associated with vertices are not stored in the DoFObjects classes but rather in the DoFHandler::vertex_dofs array.
The DoFObjects classes are not used directly, but objects of theses classes are included in the DoFLevel and DoFFaces classes.

Set the global index of the local_index-th degree of freedom located on the object with number obj_index to the value given by the last argument. The dof_handler argument is used to access the finite element that is to be used to compute the location where this data is stored.
The third argument, fe_index, must equal zero. It is otherwise unused, but we retain the argument so that we can use the same interface for non-hp and hp finite element methods, in effect making it possible to share the DoFAccessor class hierarchy between hp and non-hp classes.

Return the value 1. The meaning of this function becomes clear by looking at what the corresponding functions in the classes internal::hp::DoFObjects

Similar to the function above. Assert that the given index is zero, and then return true.
