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_node_set_boost_unordered_enable_stats[enabled].
返回值：;; 截至目前，由该表执行的插入与查找操作的统计信息描述。
注意：;; 仅当**统计计算功能启用**时可用。

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_node_set_boost_unordered_enable_stats[enabled].
效果：;; 将该哈希表所维护的内部统计数据清零。
注意：;; 仅当xref:reference/stats.adoc#stats[statistics calculation]（统计计算功能）被xref:concurrent_node_set_boost_unordered_enable_stats[enabled]（启用状态）激活时，本函数才可使用。

Deduction Guides
推导指引
A deduction guide will not participate in overload resolution if any of the following are true:
如果以下任何一条件为真，则推导指引将不参与重载决议：
- 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 container 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。

Equality Comparisons
相等性比较
operator
operator
```c++ template<class Key, class Hash, class Pred, class Alloc> bool operator==(const concurrent_node_set<Key, Hash, Pred, Alloc>& x, const concurrent_node_set<Key, Hash, Pred, Alloc>& y); ```
```c++ template<class key,="" class="" hash,="" pred,="" alloc=""> bool operator==(const concurrent_node_set<key, hash,="" pred,="" alloc="">&amp; x, const concurrent_node_set<key, hash,="" pred,="" alloc="">&amp; 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).
返回值：;; 当且仅当 `x.size() == y.size()`，且对于 `x` 中的每个元素，`y` 中都存在一个拥有相同键、值相等（使用 `operator==` 比较值类型）的元素时，返回 `true`。

Concurrency:;; Blocking on `x` and `y`. Notes:;; Behavior is undefined if the two tables don't have equivalent equality predicates.
并发：;; 对 `x` 和 `y` 进行阻塞操作。
注意：;; 若两个哈希表的相等性断言不匹配，则行为未定义。

operator!
operator!
```c++ template<class Key, class Hash, class Pred, class Alloc> bool operator!=(const concurrent_node_set<Key, Hash, Pred, Alloc>& x, const concurrent_node_set<Key, Hash, Pred, Alloc>& y); ```
```c++ template<class key,="" class="" hash,="" pred,="" alloc=""> bool operator!=(const concurrent_node_set<key, hash,="" pred,="" alloc="">&amp; x, const concurrent_node_set<key, hash,="" pred,="" alloc="">&amp; 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).
返回值：;; 当 `x.size() == y.size()` 且对于 `x` 中的每个元素，`y` 中都存在一个拥有相同键、值相等（使用 `operator==` 比较值类型）的元素时，返回 `false`。
:1670
Concurrency:;; Blocking on `x` and `y`. Notes:;; Behavior is undefined if the two tables don't have equivalent equality predicates.
并发：;; 对 `x` 和 `y` 执行阻塞操作。
注意：;; 若两个哈希表不具备等价的相等性断言，则行为未定义。

```c++ template<class key,="" class="" hash,="" pred,="" alloc=""> void swap(concurrent_node_set<key, hash,="" pred,="" alloc="">&amp; x, concurrent_node_set<key, hash,="" pred,="" alloc="">&amp; y) noexcept(noexcept(x.swap(y))); ```</key,></key,></class>
