Key	English	Chinese (Simplified Han script)
	Extracts the element with key equivalent to `k`, if it exists.	若存在键与 `k` 等价的元素，则提取该元素。
	Returns:;; A `node_type` object holding the extracted element, or empty if no element was extracted. Throws:;; Only throws an exception if it is thrown by `hasher` or `key_equal`. Notes:;; The `template<class K>` overload only participates in overload resolution if `Hash::is_transparent` and `Pred::is_transparent` are valid member typedefs. The library assumes that `Hash` is callable with both `K` and `Key` and that `Pred` is transparent. This enables heterogeneous lookup which avoids the cost of instantiating an instance of the `Key` type.	返回值：;; 一个存储被提取元素的 `node_type` 对象；若未提取任何元素，则为空。抛出异常：;; 仅当 `hasher` 或 `key_equal` 抛出异常时才会抛出。注意：;; 仅当 `Hash::is_transparent` 和 `Pred::is_transparent` 是有效的成员类型别名时，`template<class k="">` 重载版本才参与重载决议。库假定 `Hash` 可同时接受 `K` 类型与 `Key` 类型作为参数，且 `Pred` 是透明的。这支持异构查找，从而避免实例化 `Key` 类型对象带来的性能开销。</class>

	Extracts the element `x` with key equivalent to `k`, if it exists and `f(x)` is `true`.	若存在键与 `k` 等价的元素 `x`，且 `f(x)` 返回 `true`，则提取该元素。
	Returns:;; A `node_type` object holding the extracted element, or empty if no element was extracted. Throws:;; Only throws an exception if it is thrown by `hasher` or `key_equal` or `f`.

	clear	清空
	```c++ void clear() noexcept; ```	```c++ void clear() noexcept; ```
	Erases all elements in the table.	清空表中的所有元素。
	Postconditions:;; `size() == 0`, `max_load() >= max_load_factor() * bucket_count()` Concurrency:;; Blocking on `*this`.	后置条件：;; `size() == 0`，且 `max_load() >= max_load_factor() * bucket_count()` 并发特性：;; 阻塞当前容器 `*this`。
:1619	---	---
	merge	合并
	```c++ template<class H2, class P2> size_type merge(concurrent_node_map<Key, T, H2, P2, Allocator>& source); template<class H2, class P2> size_type merge(concurrent_node_map<Key, T, H2, P2, Allocator>&& source); ```	```c++ template<class h2,="" class="" p2=""> size_type merge(concurrent_node_map<key, t,="" h2,="" p2,="" allocator="">& source); template<class h2,="" class="" p2=""> size_type merge(concurrent_node_map<key, t,="" h2,="" p2,="" allocator="">&& source); ```</key,></class></key,></class>
	Move-inserts all the elements from `source` whose key is not already present in `*this`, and erases them from `source`.	将源容器 `source` 中所有*键不存在于当前容器 `this` 中的元素移动插入**到当前容器，并从 `source` 中删除这些元素。
	Returns:;; The number of elements inserted. Concurrency:;; Blocking on `*this` and `source`.	返回值：;; 插入的元素数量。并发特性：;; 阻塞当前容器 `*this` 与源容器 `source`。

	Observers	观察器
	get_allocator	get++_++allocator
	``` allocator_type get_allocator() const noexcept; ```	``` allocator_type get_allocator() const noexcept; ```

	hash_function	哈希函数
	``` hasher hash_function() const; ```	``` hasher hash_function() const; ```

	English	Chinese (Simplified Han script)	Actions
	```c++ template<class F> size_type erase_if(const key_type& k, F f); template<class K, class F> size_type erase_if(const K& k, F f); ```	```c++ template<class f=""> size_type erase_if(const key_type& k, F f); template<class k,="" class="" f=""> size_type erase_if(const K& k, F f); ```</class></class>
	Erases the element `x` with key equivalent to `k` if it exists and `f(x)` is `true`.	若存在键与 `k` 等价的元素 `x`，且 `f(x)` 返回 `true`，则删除该元素。
	Successively invokes `f` with non-const references to each of the elements in the table, and erases those for which `f` returns `true`.	依次以非常量引用为参数，对表中的每个元素调用 `f`，并删除所有 `f` 返回 `true` 的元素。
	Returns:;; The number of elements erased. Throws:;; Only throws an exception if it is thrown by `f`.	返回值：;; 删除的元素总数。抛出异常：;; 仅当 `f` 抛出异常时才会抛出。
	Parallel erase_if	并行条件擦除
	```c++ template<class ExecutionPolicy, class F> void erase_if(ExecutionPolicy&& policy, F f); ```	```c++ template<class executionpolicy,="" class="" f=""> void erase_if(ExecutionPolicy&& policy, F f); ```</class>
	Invokes `f` with non-const references to each of the elements in the table, and erases those for which `f` returns `true`. Execution is parallelized according to the semantics of the execution policy specified.	根据指定执行策略的语义并行执行操作：依次以非常量引用为参数对表中的每个元素调用 `f`，并删除所有 `f` 返回 `true` 的元素。
	```c++ void swap(concurrent_node_map& other) noexcept(boost::allocator_traits<Allocator>::is_always_equal::value \|\| boost::allocator_traits<Allocator>::propagate_on_container_swap::value); ```	```c++ void swap(concurrent_node_map& other) noexcept(boost::allocator_traits<allocator>::is_always_equal::value \|\| boost::allocator_traits<allocator>::propagate_on_container_swap::value); ```</allocator></allocator>
	Swaps the contents of the table with the parameter.	将当前表与参数表的内容进行交换。
	If `Allocator::propagate_on_container_swap` is declared and `Allocator::propagate_on_container_swap::value` is `true` then the tables' allocators are swapped. Otherwise, swapping with unequal allocators results in undefined behavior.	若声明了 `Allocator::propagate_on_container_swap` 且其值为 `true`，则交换两个表的分配器；否则，使用不相等的分配器进行交换会导致未定义行为。
	Throws:;; Nothing unless `key_equal` or `hasher` throw on swapping. Concurrency:;; Blocking on `*this` and `other`.	抛出异常：;; 除非 `key_equal` 或 `hasher` 在交换时抛出异常，否则不抛出任何异常。并发特性：;; 阻塞当前容器 `*this` 与目标容器 `other`。
