Detailed Description

An iterator over a system of generators.

A const_iterator is used to provide read-only access to each generator contained in an object of Generator_System.

Example

The following code prints the system of generators of the polyhedron ph:

  const Generator_System& gs = ph.generators();
  for (Generator_System::const_iterator i = gs.begin(),
         gs_end = gs.end(); i != gs_end; ++i)
    cout << *i << endl;

The same effect can be obtained more concisely by using more features of the STL:

  const Generator_System& gs = ph.generators();
  copy(gs.begin(), gs.end(), ostream_iterator<Generator>(cout, "\n"));
