CVSROOT: /cvs/ppl Module name: ppl Changes by: zaffanella@cs.unipr.it 2008-08-20 12:45:51 Modified files: src : BD_Shape.defs.hh BD_Shape.templates.hh Box.defs.hh Box.templates.hh Grid.defs.hh Grid_public.cc Octagonal_Shape.defs.hh Octagonal_Shape.templates.hh Pointset_Powerset.defs.hh Pointset_Powerset.templates.hh Polyhedron.defs.hh Polyhedron_public.cc Log message: The method intersection_preserving_enlarge_assign() now returns a boolean: if false is returned the intersection is empty. Using the new return value, improved the implementation for Pointset_Powerset by dropping those disjuncts that have empty intersection with all of the disjunct of the context. Corrected a bug in the Polyhedron method regarding the correct handling of equality constraints.
