NAME

       pair_set - a set of (index,value) pair (rheolef-6.7)

SYNOPSYS

       A  class  for:  l  =  {(0,3.3),...(7,8.2)}  i.e. a wrapper for STL map<size_t,T> with some
       assignment operators, such as l1  +=  l2.   This  class  is  suitable  for  use  with  the
       disarray<T> class, as disarray<pair_set> (see disarray(2)).

TODO

       template <T,A> with A=std::allocator or heap_allocator

IMPLEMENTATION

       template<class T, class A = std::allocator<std::pair<std::size_t,T> > >
       class pair_set: public std::map<std::size_t, T, std::less<std::size_t>, A> {
       public:

                                                base;
         typedef typename base::iterator        iterator;
         typedef typename base::const_iterator  const_iterator;

       // allocators:

         pair_set (const A& alloc = A());
         pair_set (const pair_set<T,A>& x, const A& alloc = A());
         pair_set<T,A>& operator= (const pair_set<T,A>& x);
         void clear ();

       // basic algebra: semantic of a sparse vector

         pair_set<T,A>& operator+= (const pair_type&     x); // c := a union {x}
         template<class B>
         pair_set<T,A>& operator+= (const pair_set<T,B>& b); // c := a union b

       // boost mpi:

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