	Serialization	序列化
	``unordered_multimap``s can be archived/retrieved by means of link:../../../../../serialization/index.html[Boost.Serialization^] using the API provided by this library. Both regular and XML archives are supported.	`unordered_multimap` 可以通过本库提供的 API，借助 link:../../../../../serialization/index.html[Boost.Serialization^] 进行归档/恢复。支持常规归档和 XML 归档。
	Saving an unordered_multimap to an archive	将 unordered_multimap 保存到归档
	Saves all the elements of an `unordered_multimap` `x` to an archive (XML archive) `ar`.	将 `unordered_multimap` 容器 `x` 的所有元素保存到归档（XML 归档） `ar` 中。
	Requires:;; `std::remove_const<key_type>::type` and `std::remove_const<mapped_type>::type` are serializable (XML serializable), and they do support Boost.Serialization `save_construct_data`/`load_construct_data` protocol (automatically suported by https://en.cppreference.com/w/cpp/named_req/DefaultConstructible[DefaultConstructible^] types).	要求：`std::remove_const<key_type>::type` 和 `std::remove_const<mapped_type>::type` 必须是可序列化的（对于 XML 归档需支持 XML 序列化），并且它们必须支持 Boost.Serialization 的 `save_construct_data`/`load_construct_data` 协议（该协议由满足 https://en.cppreference.com/w/cpp/named_req/DefaultConstructible[可默认构造^] 的类型自动支持）。</mapped_type></key_type>

	Loading an unordered_multimap from an archive	从归档加载 unordered_multimap
	Deletes all preexisting elements of an `unordered_multimap` `x` and inserts from an archive (XML archive) `ar` restored copies of the elements of the original `unordered_multimap` `other` saved to the storage read by `ar`.	删除 `unordered_multimap` 容器 `x` 中所有已存在的元素，并从归档（XML 归档）`ar` 中插入从原始 `unordered_multimap` 容器 `other` 保存到 `ar` 所读取存储中的元素恢复出的副本。
	Requires:;; `value_type` is https://en.cppreference.com/w/cpp/named_req/EmplaceConstructible[EmplaceConstructible^] from `(std::remove_const<key_type>::type&&, std::remove_const<mapped_type>::type&&)`. `x.key_equal()` is functionally equivalent to `other.key_equal()`. Note:;; If the archive was saved using a release of Boost prior to Boost 1.84, the configuration macro `BOOST_UNORDERED_ENABLE_SERIALIZATION_COMPATIBILITY_V0` has to be globally defined for this operation to succeed; otherwise, an exception is thrown.	要求：`value_type` 必须可以从 `(std::remove_const<key_type>::type&&, std::remove_const<mapped_type>::type&&)` 进行 https://en.cppreference.com/w/cpp/named_req/EmplaceConstructible[可原位构造^]。`x.key_equal()` 在功能上必须等价于 `other.key_equal()`。注意：如果归档是使用 Boost 1.84 之前版本的 Boost 保存的，则必须全局定义配置宏 `BOOST_UNORDERED_ENABLE_SERIALIZATION_COMPATIBILITY_V0` 才能使此操作成功；否则，将抛出异常。</mapped_type></key_type>

	Saving an iterator/const_iterator to an archive	将迭代器/常量迭代器保存到归档
	Saves the positional information of an `iterator` (`const_iterator`) `it` to an archive (XML archive) `ar`. `it` can be and `end()` iterator.	将迭代器（或常量迭代器）`it` 的位置信息保存到归档（XML 归档）`ar` 中。`it` 可以是一个 `end()` 迭代器。
	Requires:;; The `unordered_multimap` `x` pointed to by `it` has been previously saved to `ar`, and no modifying operations have been issued on `x` between saving of `x` and saving of `it`.	要求：`it` 所指向的 `unordered_multimap` 容器 `x` 必须先被保存到 `ar` 中，并且在保存 `x` 和保存 `it` 之间，不能对 `x` 执行任何修改操作。
:1537	---	---
	Loading an iterator/const_iterator from an archive	从归档加载迭代器/常量迭代器
	Makes an `iterator` (`const_iterator`) `it` point to the restored position of the original `iterator` (`const_iterator`) saved to the storage read by an archive (XML archive) `ar`.	使迭代器（或常量迭代器）`it` 指向原始迭代器（或常量迭代器）被保存到归档（XML 归档）`ar` 所读取存储中的位置恢复后的位置。
	Requires:;; If `x` is the `unordered_multimap` `it` points to, no modifying operations have been issued on `x` between loading of `x` and loading of `it`.	要求：如果 `x` 是 `it` 所指向的 `unordered_multimap` 容器，则在加载 `x` 和加载 `it` 之间，不能对 `x` 执行任何修改操作。

	Synopsis	概要
	_Pred_	_Pred_
	Bucket Count Constructor	桶数构造函数
	Copy Constructor	复制构造函数
	Allocator Constructor	分配器构造函数
	```c++ unordered_multimap(const unordered_multimap& other, const Allocator& a); ```	```c++ unordered_multimap(const unordered_multimap& other, const Allocator& a); ```
	Initializer List Assignment	初始化列表赋值
	Returns:;; An iterator which refers to the past-the-end value for the container.	返回：指向容器尾后值的迭代器。
	Modifiers	修改器
	Inserts an object, constructed with the arguments `args`, in the container.	插入一个使用参数 `args` 构造的对象到容器中。
	Inserts an object, constructed with the arguments args, in the container.	插入一个使用参数 `args` 构造的对象到容器中。
	`position` is a suggestion to where the element should be inserted.	`position` 是关于元素插入位置的建议。
	```c++ unordered_multimap(unordered_multimap&& other); ```	```c++ unordered_multimap(unordered_multimap&& other); ```
	```c++ template<class Key, class T, class Hash, class Pred, class Alloc> bool operator!=(const unordered_multimap<Key, T, Hash, Pred, Alloc>& x, const unordered_multimap<Key, T, Hash, Pred, Alloc>& y); ```	```c++ template<class key,="" class="" t,="" hash,="" pred,="" alloc=""> bool operator!=(const unordered_multimap<key, t,="" hash,="" pred,="" alloc="">& x, const unordered_multimap<key, t,="" hash,="" pred,="" alloc="">& y); ```</key,></key,></class>
	Loading an unordered_multimap from an archive	从归档加载 unordered_multimap
	Return `false` if `x.size() == y.size()` and for every equivalent key group in `x`, there is a group in `y` for the same key, which is a permutation (using `operator==` to compare the value types).	若 `x.size() == y.size()` 且对于 `x` 中的每个等价键组，在 `y` 中均存在一个具有相同键的组，并且该组是 `x` 中对应组的置换（使用 `operator==` 比较值类型），则返回 `false`。
	Swap	交换
	Effects:;; `x.swap(y)` Throws:;; Doesn't throw an exception unless it is thrown by the copy constructor or copy assignment operator of `key_equal` or `hasher`. Notes:;; The exception specifications aren't quite the same as the C++11 standard, as the equality predicate and hash function are swapped using their copy constructors.	效果：`x.swap(y)` 抛出：除非 `key_equal` 或 `hasher` 的拷贝构造函数或拷贝赋值运算符抛出异常，否则不抛出任何异常。注意：异常规范与 C++11 标准不完全相同，因为相等谓词和哈希函数是使用其拷贝构造函数进行交换的。
	Returns:;; The number of erased elements. Notes:;; Equivalent to: + + ```c++ auto original_size = c.size(); for (auto i = c.begin(), last = c.end(); i != last; ) { if (pred(*i)) { i = c.erase(i); } else { ++i; } } return original_size - c.size(); ``` + Note that the references passed to `pred` are non-const.	返回：被擦除的元素数量。注意：等价于： ```c++auto original_size = c.size();for (auto i = c.begin(), last = c.end(); i != last; ) {if (pred(*i)) {i = c.erase(i);} else {++i;}}return original_size - c.size(); ``` 注意，传递给 `pred` 的引用是非常量的。
