index_set - a set of indexes (rheolef-6.7)


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 disarray<T> class, as disarray<index_set> (see disarray(2)).


class index_set : public std::set<std::size_t> {
// 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:
#ifdef _RHEOLEF_HAVE_MPI template <class Archive> void serialize (Archive& ar, const unsigned int version); #endif // _RHEOLEF_HAVE_MPI };
