A multiset is a kind of associative container that supports equivalent keys //! (possibly contains multiple copies of the same key value) and provides for //! fast retrieval of the keys themselves. Class multiset supports bidirectional iterators. //! //! A multiset satisfies all of the requirements of a container and of a reversible //! container, and of an associative container). multiset also provides most operations //! described for duplicate keys. //! //! \tparam Key is the type to be inserted in the set, which is also the key_type //! \tparam Compare is the comparison functor used to order keys //! \tparam Allocator is the allocator to be used to allocate memory for this container //! \tparam Options is an packed option type generated using using boost::container::tree_assoc_options. template <class Key, class Compare = std::less<Key>, class Allocator = new_allocator<Key>, class Options = tree_assoc_defaults > #else template <class Key, class Compare, class Allocator, class Options> #endif class multiset /// @cond : public container_detail::tree <Key,container_detail::identity<Key>, Compare, Allocator, Options> /// @endcond { #ifndef BOOST_CONTAINER_DOXYGEN_INVOKED private: BOOST_COPYABLE_AND_MOVABLE(multiset) typedef container_detail::tree <Key,container_detail::identity<Key>, Compare, Allocator, Options> base_t; #endif //#ifndef BOOST_CONTAINER_DOXYGEN_INVOKED public: ////////////////////////////////////////////// // // types // ////////////////////////////////////////////// typedef Key key_type; typedef Key value_type; typedef Compare key_compare; typedef Compare value_compare; typedef ::boost::container::allocator_traits<Allocator> allocator_traits_type; typedef typename ::boost::container::allocator_traits<Allocator>::pointer pointer; typedef typename ::boost::container::allocator_traits<Allocator>::const_pointer const_pointer; typedef typename ::boost::container::allocator_traits<Allocator>::reference reference; typedef typename ::boost::container::allocator_traits<Allocator>::const_reference const_reference; typedef typename ::boost::container::allocator_traits<Allocator>::size_type size_type; typedef typename ::boost::container::allocator_traits<Allocator>::difference_type difference_type; typedef Allocator allocator_type; typedef typename BOOST_CONTAINER_IMPDEF(base_t::stored_allocator_type) stored_allocator_type; typedef typename BOOST_CONTAINER_IMPDEF(base_t::iterator) iterator; typedef typename BOOST_CONTAINER_IMPDEF(base_t::const_iterator) const_iterator; typedef typename BOOST_CONTAINER_IMPDEF(base_t::reverse_iterator) reverse_iterator; typedef typename BOOST_CONTAINER_IMPDEF(base_t::const_reverse_iterator) const_reverse_iterator; typedef typename BOOST_CONTAINER_IMPDEF(base_t::node_type) node_type; ////////////////////////////////////////////// // // construct/copy/destroy // ////////////////////////////////////////////// //! @copydoc ::boost::container::set::set() multiset() BOOST_NOEXCEPT_IF(container_detail::is_nothrow_default_constructible<Allocator>::value && container_detail::is_nothrow_default_constructible<Compare>::value) : base_t() {} //! @copydoc ::boost::container::set::set(const Compare&, const allocator_type&) explicit multiset(const Compare& comp, const allocator_type& a = allocator_type()) : base_t(comp, a) {} //! @copydoc ::boost::container::set::set(const allocator_type&) explicit multiset(const allocator_type& a) : base_t(a) {} //! @copydoc ::boost::container::set::set(InputIterator, InputIterator, const Compare& comp, const allocator_type&) template <class InputIterator> multiset(InputIterator first, InputIterator last, const Compare& comp = Compare(), const allocator_type& a = allocator_type()) : base_t(false, first, last, comp, a) {} //! @copydoc ::boost::container::set::set(InputIterator, InputIterator, const allocator_type&) template <class InputIterator> multiset(InputIterator first, InputIterator last, const allocator_type& a) : base_t(false, first, last, key_compare(), a) {} //! <b>Effects</b>: Constructs an empty multiset using the specified comparison object and //! allocator, and inserts elements from the ordered range [first ,last ).
