	`boost::unordered_multimap` — An unordered associative container that associates keys with another value. The same key can be stored multiple times.	`boost::unordered_multimap` — 一个无序关联容器，将键与对应值相关联。同一个键可以多次存储。

	`Key` must be https://en.cppreference.com/w/cpp/named_req/Erasable[Erasable^] from the container (i.e. `allocator_traits` can destroy it).	`Key` 必须可以从容器中 https://en.cppreference.com/w/cpp/named_req/Erasable[Erasable^]（即 `allocator_traits` 能够销毁它）。

	_Hash_	_Hash_
	A unary function object type that acts a hash function for a `Key`. It takes a single argument of type `Key` and returns a value of type `std::size_t`.	一个一元函数对象类型，用作 `Key` 的哈希函数。它接受一个 `Key` 类型的参数，并返回一个 `std::size_t` 类型的值。
	_Pred_	_Pred_
	A binary function object that implements an equivalence relation on values of type `Key`. A binary function object that induces an equivalence relation on values of type `Key`. It takes two arguments of type `Key` and returns a value of type bool.	一个二元函数对象，用于在 `Key` 类型的值上实现等价关系。它接受两个 `Key` 类型的参数，并返回一个 `bool` 类型的值。
	_Allocator_	_Allocator_
	An allocator whose value type is the same as the container's value type.	一个分配器，其值类型与容器的值类型相同。
	Allocators using https://en.cppreference.com/w/cpp/named_req/Allocator#Fancy_pointers[fancy pointers] are supported.	支持使用 https://en.cppreference.com/w/cpp/named_req/Allocator#Fancy_pointers[异形指针] 的分配器。
	The elements are organized into buckets. Keys with the same hash code are stored in the same bucket.	元素被组织到桶中。具有相同哈希码的键存储在同一桶中。
	The number of buckets can be automatically increased by a call to insert, or as the result of calling rehash.	桶的数量可以通过调用 insert 自动增加，或者作为调用 rehash 的结果。

	Globally define this macro to support loading of ``unordered_multimap``s saved to a Boost.Serialization archive with a version of Boost prior to Boost 1.84.	全局定义此宏以支持加载由 Boost 1.84 之前版本的 Boost 保存到 Boost.Serialization 归档中的 `unordered_multimap`。
	Typedefs	类型定义
	An iterator whose value type is `value_type`.	一种迭代器，其值类型为 `value_type` 。
:294	The iterator category is at least a forward iterator.	迭代器类别至少为前向迭代器。
	Convertible to `const_iterator`.	可转换为 `const_iterator` 。

	A constant iterator whose value type is `value_type`.	一个常量迭代器，其值类型为 `value_type` 。
:307	The iterator category is at least a forward iterator.	迭代器类别至少为前向迭代器。
