NAME

       index_set - a set of indexes (rheolef-6.1)

SYNOPSYS

       A  class  for:  l = {1,3,...9} i.e. a wrapper for STL set<size_t> with some assignment operators, such as l1 += l2.  This class is suitable
       for use with the array<T> class, as array<index_set> (see array(2)).

IMPLEMENTATION

       class index_set : public std::set<std::size_t> {
       public:

       // typedefs:

	 typedef std::set<std::size_t>	  base;
	 typedef std::size_t		  value_type;
	 typedef std::size_t		  size_type;

       // allocators:

	 index_set ();
	 index_set (const index_set& x);
	 index_set& operator= (const index_set& x);
	 template <int N>
	 index_set& operator= (size_type x[N]);
	 void clear ();

       // basic algebra:

	 void	    insert     (size_type dis_i);    // a := a union {dis_i}
	 index_set& operator+= (size_type dis_i);    // idem
	 index_set& operator+= (const index_set& b); // a := a union b

	 // a := a union b
	 void inplace_union	   (const index_set& b);
	 void inplace_intersection (const index_set& b);

	 // c := a union b
	 friend void set_union	      (const index_set& a, const index_set& b, index_set& c);
	 friend void set_intersection (const index_set& a, const index_set& b, index_set& c);

       // io:

	 friend std::istream& operator>> (std::istream& is, index_set& x);
	 friend std::ostream& operator<< (std::ostream& os, const index_set& x);

       // boost mpi:

	 template <class Archive>
	 void serialize (Archive& ar, const unsigned int version);
       };
