CVSROOT: /cvs/ppl Module name: ppl Changes by: zaffanella@cs.unipr.it 2001-10-21 15:50:41

Modified files: src : ConSys.defs.hh GenSys.defs.hh Generator.defs.hh Generator.inlines.hh LinExpression.defs.hh LinExpression.inlines.hh Polyhedron.defs.hh

Log message: Systems of constraints and generators do not define polyhedra; rather, they may "correspond to" a given polyhedron (the one that would be built by applying the adequate constructor). A system of generator does not need to include a vertex, in general. The vertex is needed if the system of generators is meant to correspond to a non-empty polyhedron. The detailed description of class Generator changed to highlight that vertices, lines and rays are represented as a type plus a direction in the space.
