Key English Chinese (Simplified Han script) Actions
```c++ float max_load_factor() const noexcept; ```
```c++ float max_load_factor() const noexcept; ```
Returns:;; Returns the table's maximum load factor.
返回值：容器的最大负载因子。
:1615

---
Set max_load_factor
设置最大负载因子
```c++ void max_load_factor(float z); ```
```c++ void max_load_factor(float z); ```
Effects:;; Does nothing, as the user is not allowed to change this parameter. Kept for compatibility with `boost::unordered_map`.
效果：无任何操作，用户不允许修改此参数。保留该函数是为了与 `boost::unordered_map` 保持兼容。
:1625

max_load
max_load（最大负载）
```c++ size_type max_load() const noexcept; ```
```c++ size_type max_load() const noexcept; ```
Returns:;; The maximum number of elements the table can hold without rehashing, assuming that no further elements will be erased. Note:;; After construction, rehash or clearance, the table's maximum load is at least `max_load_factor() * bucket_count()`. This number may decrease on erasure under high-load conditions. + + In the presence of concurrent insertion operations, the value returned may not accurately reflect the true state of the table right after execution.
返回值：容器在不进行重哈希的前提下可容纳的最大元素数量（假定不会再擦除任何元素）。
说明：容器在构造、重哈希或清空后，其最大负载量至少为 `max_load_factor() * bucket_count()`。在高负载条件下执行擦除操作时，该数值可能会降低。
若存在并发插入操作，返回值可能无法精确反映容器执行后的真实状态。

rehash
重哈希
```c++ void rehash(size_type n); ```
```c++ void rehash(size_type n); ```
Changes if necessary the size of the bucket array so that there are at least `n` buckets, and so that the load factor is less than or equal to the maximum load factor. When applicable, this will either grow or shrink the `bucket_count()` associated with the table.
效果：必要时调整桶数组的大小，使桶数量至少为 `n`，且负载因子小于等于最大负载因子。
适用场景下，该操作会**增大或缩小**容器的桶数量 `bucket_count()`。
When `size() == 0`, `rehash(0)` will deallocate the underlying buckets array.
当容器大小 `size() == 0` 时，调用 `rehash(0)` 会**释放底层的桶数组内存**。

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`。
reserve
保留
```c++ void reserve(size_type n); ```
```c++ void reserve(size_type n); ```
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。

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。

reset_stats
reset_stats
```c++ void reset_stats() noexcept; ```
```c++ void reset_stats() noexcept; ```
