Key	English	Chinese (Simplified Han script)
	Equivalent to `a.rehash(ceil(n / a.max_load_factor()))`.	等价于 `a.rehash(ceil(n / a.max_load_factor()))`。
	Similar to `rehash`, this function can be used to grow or shrink the number of buckets in the table.	与 `rehash` 功能类似，该函数可用于增大或缩小容器的桶数量。
:1669	Invalidates pointers and references to elements, and changes the order of elements.	会使指向元素的指针和引用失效，并改变元素的存储顺序。
	Throws:;; The function has no effect if an exception is thrown, unless it is thrown by the table's hash function or comparison function. Concurrency:;; Blocking on `*this`.	异常：若抛出异常，函数无任何效果（由容器的哈希函数或比较函数抛出的异常除外）。并发：阻塞当前对象 `*this`。
:1675	---	---
	Statistics	统计信息
	get_stats	get_stats
	```c++ stats get_stats() const; ```	```c++ stats get_stats() const; ```
	Returns:;; A statistical description of the insertion and lookup operations performed by the table so far. Notes:;; Only available if xref:reference/stats.adoc#stats[statistics calculation] is xref:concurrent_flat_map_boost_unordered_enable_stats[enabled].	返回值：容器截至目前执行的插入与查找操作的统计描述信息。说明：仅当启用统计计算时，该函数才可用。
:1688	---	---
	reset_stats	reset_stats
	```c++ void reset_stats() noexcept; ```	```c++ void reset_stats() noexcept; ```
	Effects:;; Sets to zero the internal statistics kept by the table. Notes:;; Only available if xref:reference/stats.adoc#stats[statistics calculation] is xref:concurrent_flat_map_boost_unordered_enable_stats[enabled].	效果：将容器维护的内部统计数据归零。说明：仅当启用统计计算时，该函数才可用。

	Deduction Guides	推导指引
	A deduction guide will not participate in overload resolution if any of the following are true:	满足以下任一条件时，推导指引不参与重载决议：
	- It has an `InputIterator` template parameter and a type that does not qualify as an input iterator is deduced for that parameter. - It has an `Allocator` template parameter and a type that does not qualify as an allocator is deduced for that parameter. - It has a `Hash` template parameter and an integral type or a type that qualifies as an allocator is deduced for that parameter. - It has a `Pred` template parameter and a type that qualifies as an allocator is deduced for that parameter.	- 该推导指引包含 `InputIterator` 模板参数，且为此参数推导出的类型不符合输入迭代器的要求。 - 该推导指引包含 `Allocator` 模板参数，且为该参数推导出的类型不符合分配器要求。 - 该推导指引包含 `Hash` 模板参数，且为该参数推导出的类型为整型或符合分配器要求。 - 该推导指引包含 `Pred` 模板参数，且为该参数推导出的类型符合分配器要求。
	A `size_type` parameter type in a deduction guide refers to the `size_type` member type of the table type deduced by the deduction guide. Its default value coincides with the default value of the constructor selected.	推导指引中的 `size++_++type` 参数类型，指向由该推导指引所推导容器类型的 `size++_++type` 成员类型。其默认值与所选构造函数的默认值一致。
	__iter-value-type__	_iter-value-type_
	__iter-key-type__	__iter-key-type__
	__iter-mapped-type__	__iter-mapped-type__
	__iter-to-alloc-type__	__iter-to-alloc-type__
	Equality Comparisons	相等性比较
	operator	operator
	```c++ template<class Key, class T, class Hash, class Pred, class Alloc> bool operator==(const concurrent_flat_map<Key, T, Hash, Pred, Alloc>& x, const concurrent_flat_map<Key, T, Hash, Pred, Alloc>& y); ```	```c++ template<class key,="" class="" t,="" hash,="" pred,="" alloc=""> bool operator==(const concurrent_flat_map<key, t,="" hash,="" pred,="" alloc="">& x, const concurrent_flat_map<key, t,="" hash,="" pred,="" alloc="">& y); ```</key,></key,></class>
	Returns `true` if `x.size() == y.size()` and for every element in `x`, there is an element in `y` with the same key, with an equal value (using `operator==` to compare the value types).	若 `x.size() == y.size()`，且对于 `x` 中的每个元素，`y` 中均存在拥有相同键、值相等（使用 `operator==` 比较值类型）的元素，则返回 `true`。
:1758	Concurrency:;; Blocking on `x` and `y`. Notes:;; Behavior is undefined if the two tables don't have equivalent equality predicates.	并发：阻塞 `x` 和 `y`。说明：若两个容器的相等判断谓词不一致，行为未定义。
:1761	---	---
	operator!	operator!
	```c++ template<class Key, class T, class Hash, class Pred, class Alloc> bool operator!=(const concurrent_flat_map<Key, T, Hash, Pred, Alloc>& x, const concurrent_flat_map<Key, T, Hash, Pred, Alloc>& y); ```	```c++ template<class key,="" class="" t,="" hash,="" pred,="" alloc=""> bool operator!=(const concurrent_flat_map<key, t,="" hash,="" pred,="" alloc="">& x, const concurrent_flat_map<key, t,="" hash,="" pred,="" alloc="">& y); ```</key,></key,></class>
	Returns `false` if `x.size() == y.size()` and for every element in `x`, there is an element in `y` with the same key, with an equal value (using `operator==` to compare the value types).	若`x.size() == y.size()`，且`x`中每个元素在`y`中都存在键相同、值相等（使用`operator==`比较值类型）的元素，则返回`false`。

Args, class F1, class F2> bool emplace_and_cvisit(Args&&... args, F1&& f1, F2&& f2); ```	```c++ template<class... args,="" class="" f1,="" f2=""> bool emplace_and_visit(Args&&... args, F1&& f1, F2&& f2); template<class... args,="" class="" f1,="" f2=""> bool emplace_and_cvisit(Args&&... args, F1&& f1, F2&& f2); ```</class...></class...>
	Move insert_and_[c]visit	移动 insert_and_[c]visit
	Parallel erase_if	并行条件擦除
	rehash	重哈希
	Requires:;; `value_type` is https://en.cppreference.com/w/cpp/named_req/CopyInsertable[CopyInsertable^] Concurrency:;; Blocking on `*this`.	要求：`value_type` 需满足 https://en.cppreference.com/w/cpp/named_req/CopyInsertable[可复制插入^] 要求。并发：阻塞 `*this`。
	For each element `k` in the range [`first`, `last`), if there is an element `x` in the container with key equivalent to `k`, invokes `f` with a reference to `x`. Such reference is const iff `*this` is const.	对范围 [first, last) 中的每个键 k：如果容器中存在键与 k 等价的元素 x，则以 x 的引用调用函数 f。当且仅当当前容器 *this 为常量（const）时，该引用为常量引用。
	Although functionally equivalent to individually invoking xref:concurrent_flat_map_cvisit[`[c\]visit`] for each key, bulk visitation performs generally faster due to internal streamlining optimizations. It is advisable that `std::distance(first,last)` be at least xref:#concurrent_flat_map_constants[`bulk_visit_size`] to enjoy a performance gain: beyond this size, performance is not expected to increase further.	尽管功能上等价于对每个键单独调用 [c]visit，但批量访问因内部流线型优化，通常性能更高。建议 std::distance(first,last) 至少达到 bulk_visit_size 阈值时再使用，以获得性能提升；超过该大小后，性能不会进一步提升。
	[c]visit_all	[c]visit_all
	```c++ template<class F> bool visit_while(F f); template<class F> bool visit_while(F f) const; template<class F> bool cvisit_while(F f) const; ```	```c++ template<class f=""> bool visit_while(F f); template<class f=""> bool visit_while(F f) const; template<class f=""> bool cvisit_while(F f) const; ```</class></class></class>
	```c++ template<class K, class T, class H, class P, class A, class Predicate> typename concurrent_flat_map<K, T, H, P, A>::size_type erase_if(concurrent_flat_map<K, T, H, P, A>& c, Predicate pred); ```	```c++ template<class k,="" class="" t,="" h,="" p,="" a,="" predicate=""> typename concurrent_flat_map<k, t,="" h,="" p,="" a="">::size_type erase_if(concurrent_flat_map<k, t,="" h,="" p,="" a="">& c, Predicate pred); ```</k,></k,></class>
	Serialization	序列化
	``concurrent_flat_map``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.	`concurrent++_++flat++_++map` 可通过本组件库提供的 API，借助 link:../../../../../serialization/index.html[Boost.Serialization] 进行归档/检索。支持常规归档与 XML 归档两种格式。
	Saving an concurrent_flat_map to an archive	将concurrent++_++flat++_++map保存到归档
	Saves all the elements of a `concurrent_flat_map` `x` to an archive (XML archive) `ar`.	将 `concurrent++_++flat++_++map` 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). Concurrency:;; Blocking on `x`.	要求：`std::remove_const<key_type>::type` 和 `std::remove_const<mapped_type>::type` 必须是可序列化的（支持 XML 序列化），并且它们支持 Boost.Serialization 的 `save_construct_data` / `load_construct_data` 协议（https://en.cppreference.com/w/cpp/named_req/DefaultConstructible[可默认构造^] 类型自动支持该协议）。并发：阻塞 `x`。</mapped_type></key_type>
