	English Returns:;; A boolean indicating whether or not there is an element with key equal to `k` in the table. 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. + + In the presence of concurrent insertion operations, the value returned may not accurately reflect the true state of the table right after execution.

	English Effects:;; If the container does not already contain an elements with a key equivalent to `k`, inserts the value `std::pair<key_type const, mapped_type>(k, mapped_type())`. Returns:;; A reference to `x.second` where `x` is the element already in the container, or the newly inserted element with a key equivalent to `k`. Throws:;; If an exception is thrown by an operation other than a call to `hasher` the function has no effect. Notes:;; Can invalidate iterators, but only if the insert causes the load factor to be greater to or equal to the maximum load factor. + + Pointers and references to elements are never invalidated. + + 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.
	Chinese (Simplified Han script) ↹ ↵ NBS … 「 」 『 』 ﹙-﹚ ‐ – — 效果：;; 如果容器中尚不存在键与 `k` 等价的元素，则插入值 `std::pair<key_type const,="" mapped_type="">(k, mapped_type())`。 返回：;; 指向 `x.second` 的引用，其中 `x` 是容器中已存在的元素，或者是键与 `k` 等价的新插入元素。 抛出：;; 如果除调用 `hasher` 之外的操作抛出异常，则该函数无效。 备注：;; 可能使迭代器失效，但仅当插入导致负载因子大于或等于最大负载因子时才会发生。 此外，指向元素的指针和引用永远不会失效。 另外，仅当 `Hash::is_transparent` 和 `Pred::is_transparent` 是有效的成员 typedef 时，`template<class k="">` 重载才会参与重载决议。库假定 `Hash` 可同时以 `K` 和 `Key` 类型调用，且 `Pred` 是透明的。这支持了异构查找，从而避免了实例化 `Key` 类型的开销。</class></key_type> 466/9900 · 990 Needs editing
