	English	Chinese (Simplified Han script)	Actions
	Configuration macros	配置宏
	Bucket Count Constructor	桶数构造函数
	Iterator Range Constructor	迭代器范围构造函数
	```c++ unordered_multiset(const unordered_multiset& other); ```	```c++ unordered_multiset(const unordered_multiset& other); ```
	initializer_list Constructor with Bucket Count and Hasher and Allocator	带桶数、哈希函数和分配器的初始化列表构造函数
	```c++ unordered_multiset(std::initializer_list<value_type> il, size_type n, const hasher& hf, const allocator_type& a); ```	```c++ unordered_multiset(std::initializer_list<value_type> il, size_type n, const hasher& hf, const allocator_type& a); ```</value_type>
	Constructs an empty container with at least `n` buckets, using `hf` as the hash function, `a` as the allocator and a maximum load factor of 1.0 and inserts the elements from `il` into it.	构造一个至少包含 `n` 个桶的空容器，使用 `hf` 作为哈希函数，`a` 作为分配器，最大负载因子为 `1.0`，并将 `il` 中的元素插入其中。
	Destructor	析构函数
	```c++ ~unordered_multiset(); ```	```c++ ~unordered_multiset(); ```
	Note:;; The destructor is applied to every element, and all memory is deallocated	注意：析构函数会应用于每个元素，并且所有内存都会被释放。
	```c++ unordered_multiset& operator=(const unordered_multiset& other); ```	```c++ unordered_multiset& operator=(const unordered_multiset& other); ```
	The assignment operator. Copies the contained elements, hash function, predicate and maximum load factor but not the allocator.	赋值运算符。拷贝所包含的元素、哈希函数、谓词和最大负载因子，但不拷贝分配器。
	If `Alloc::propagate_on_container_copy_assignment` exists and `Alloc::propagate_on_container_copy_assignment::value` is `true`, the allocator is overwritten, if not the copied elements are created using the existing allocator.	如果 `Alloc::propagate_on_container_copy_assignment` 存在且 `Alloc::propagate_on_container_copy_assignment::value` 为 `true`，则分配器会被覆盖；否则，拷贝的元素将使用现有的分配器创建。
	```c++ unordered_multiset& operator=(unordered_multiset&& other) noexcept(boost::allocator_traits<Allocator>::is_always_equal::value && boost::is_nothrow_move_assignable_v<Hash> && boost::is_nothrow_move_assignable_v<Pred>); ``` The move assignment operator.	```c++unordered_multiset& operator=(unordered_multiset&& other) noexcept(boost::allocator_traits<allocator>::is_always_equal::value && boost::is_nothrow_move_assignable_v<hash> && boost::is_nothrow_move_assignable_v<pred>);```移动赋值运算符。</pred></hash></allocator>
	```c++ const_iterator cend() const noexcept; ```	```c++ const_iterator cend() const noexcept; ```
	Returns:;; A `const_iterator` which refers to the past-the-end value for the container.	返回：指向容器尾后值的 `const_iterator`。
	Size and Capacity	大小与容量
	Returns:;; `size()` of the largest possible container.	返回：可能的最大容器的 `size()`。
	Requires:;; `value_type` is https://en.cppreference.com/w/cpp/named_req/EmplaceConstructible[EmplaceConstructible^] into `X` from `args`. Returns:;; An iterator pointing to the inserted element. Throws:;; If an exception is thrown by an operation other than a call to `hasher` the function has no effect. Notes:;; Can invalidate iterators, but only if the insert causes the load factor to be greater to or equal to the maximum load factor. + + Pointers and references to elements are never invalidated.	要求：`value_type` 必须可以从 `args` 出发在 `X` 中进行 https://en.cppreference.com/w/cpp/named_req/EmplaceConstructible[可原位构造^]。返回：指向已插入元素的迭代器。抛出：如果除调用 `hasher` 之外的操作抛出异常，则该函数无效果。注意：可能使迭代器失效，但仅当插入导致负载因子大于或等于最大负载因子时才会发生。指向元素的指针和引用永远不会失效。
	emplace_hint	emplace_hint
	Move Insert	移动插入
	```c++ iterator insert(value_type&& obj); ```	```c++ iterator insert(value_type&& obj); ```
	Requires:;; `value_type` is https://en.cppreference.com/w/cpp/named_req/MoveInsertable[MoveInsertable^]. Returns:;; An iterator pointing to the inserted element. Throws:;; If an exception is thrown by an operation other than a call to `hasher` the function has no effect. Notes:;; Can invalidate iterators, but only if the insert causes the load factor to be greater to or equal to the maximum load factor. + + Pointers and references to elements are never invalidated.	要求：`value_type` 满足 https://en.cppreference.com/w/cpp/named_req/MoveInsertable[可移动插入^]。返回：指向已插入元素的迭代器。抛出：如果除调用 `hasher` 之外的操作抛出异常，则该函数无效果。注意：可能使迭代器失效，但仅当插入导致负载因子大于或等于最大负载因子时才会发生。指向元素的指针和引用永远不会失效。
	Copy Insert with Hint	带提示的复制插入
	```c++ iterator insert(const_iterator hint, const value_type& obj); ```	```c++ iterator insert(const_iterator hint, const value_type& obj); ```
	Requires:;; `value_type` is https://en.cppreference.com/w/cpp/named_req/CopyInsertable[CopyInsertable^]. Returns:;; An iterator pointing to the inserted element. Throws:;; If an exception is thrown by an operation other than a call to `hasher` the function has no effect. Notes:;; The standard is fairly vague on the meaning of the hint. But the only practical way to use it, and the only way that Boost.Unordered supports is to point to an existing element with the same key. + + Can invalidate iterators, but only if the insert causes the load factor to be greater to or equal to the maximum load factor. + + Pointers and references to elements are never invalidated.	要求：`value_type` 满足 https://en.cppreference.com/w/cpp/named_req/CopyInsertable[可拷贝插入^]。返回：指向已插入元素的迭代器。抛出：如果除调用 `hasher` 之外的操作抛出异常，则该函数无效果。注意：标准关于 `hint` 的含义表述相当模糊。但唯一实际的使用方式，也是 Boost.Unordered 支持的唯一方式，是将其指向一个具有相同键的已存在元素。可能使迭代器失效，但仅当插入导致负载因子大于或等于最大负载因子时才会发生。指向元素的指针和引用永远不会失效。
	Insert with Hint and `node_handle`	带提示和 `node_handle` 的插入
	```c++ iterator insert(const_iterator hint, node_type&& nh); ```	```c++ iterator insert(const_iterator hint, node_type&& nh); ```
	Returns:;; The iterator following `position` before the erasure. Throws:;; Only throws an exception if it is thrown by `hasher` or `key_equal`. Notes:;; In older versions this could be inefficient because it had to search through several buckets to find the position of the returned iterator. The data structure has been changed so that this is no longer the case, and the alternative erase methods have been deprecated.	返回：`position` 在被擦除之前的后一个迭代器。抛出：仅当 `hasher` 或 `key_equal` 抛出异常时才会抛出。注意：在旧版本中，此操作可能效率较低，因为它需要搜索多个桶以找到返回迭代器的位置。数据结构已经更改，不再是这种情况，并且备用的擦除方法已被弃用。
	```c++ size_type erase(const key_type& k); template<class K> size_type erase(K&& x); ```	```c++ size_type erase(const key_type& k); template<class k=""> size_type erase(K&& x); ```</class>
