NAME

       domain_indirect - a named part of a finite element mesh

DESCRIPTION

       The  domain_indirect  class defines a container for a part of a finite element mesh.  This
       describes the connectivity of  edges  or  faces.   This  class  is  usefull  for  boundary
       condition setting.

IMPLEMENTATION NOTE

       The  domain class is splitted into two parts.  The first one is the domain_indirect class,
       that contains the main renumbering features: it acts as a  indirect  on  a  geo  class(see
       geo(2)).  The second one is the domain class, that simply contains two smart_pointers: one
       on a domain_indirect and the second on the geo where renumbering  is  acting.   Thus,  the
       domain class develops a complete geo-like interface, via the geo_abstract_rep pure virtual
       class derivation, and can be used by the space class (see space(2)).   The  split  between
       domain_indirect  and  domain  is  necessary,  because  the  geo  class  contains a list of
       domain_indirect.  It cannot contains a list of domain classes,  that  refers  to  the  geo
       class  itself: a loop in reference counting leads to a blocking situation in the automatic
       deallocation.
