Insert Iterator Range
迭代器范围插入
```c++ template<class InputIterator> size_type insert(InputIterator first, InputIterator last); ```
```c++ template<class inputiterator=""> size_type insert(InputIterator first, InputIterator last); ```</class>
:1001
Equivalent to [listing,subs="+macros,+quotes"]
等价于 [listing,subs="+macros,+quotes"]
:1008
Returns:;; The number of elements inserted.
返回值：;; 成功插入的元素数量。

Insert Initializer List
初始化列表插入
```c++ size_type insert(std::initializer_list<value_type> il); ```
```c++ size_type insert(std::initializer_list<value_type> il); ```</value_type>
:1017
Equivalent to [listing,subs="+macros,+quotes"]

Insert Node
节点插入
```c++ insert_return_type insert(node_type&& nh); ```
```c++ insert_return_type insert(node_type&amp;&amp; nh); ```
If `nh` is not empty, inserts the associated element in the table if and only if there is no element in the table with a key equivalent to `nh.value()`. `nh` is empty when the function returns.
若 `nh` 非空，则当且仅当哈希表中不存在与 `nh.value()` 键等价的元素时，将其关联元素插入哈希表。函数返回时 `nh` 变为空。
:1037
Returns:;; An `insert_return_type` object constructed from `inserted` and `node`: +
返回值：;; 由 `inserted` 和 `node` 构造的 `insert_return_type` 对象。
:1038
If `nh` is empty, `inserted` is `false` and `node` is empty.
若 `nh` 为空，则 `inserted` 为 `false` 且 `node` 为空。
:1039
Otherwise if the insertion took place, `inserted` is true and `node` is empty.
若插入操作成功，则 `inserted` 为 true， 且 `node` 为空。
:1040
If the insertion failed, `inserted` is false and `node` has the previous value of `nh`.
若插入操作失败，则 `inserted` 为 false ，且 `node` 保留 `nh` 的原值。
Throws:;; If an exception is thrown by an operation other than a call to `hasher` the function has no effect. Concurrency:;; Blocking on rehashing of `*this`. Notes:;; Behavior is undefined if `nh` is not empty and the allocators of `nh` and the container are not equal.
若 `nh` 非空，则当且仅当容器中不存在与 `nh.value()` 等效的键时，插入其关联的元素。函数返回时 `nh` 为空。

emplace_or_[c]visit
```c++ template<class... Args, class F> bool emplace_or_visit(Args&&... args, F&& f); template<class... Args, class F> bool emplace_or_cvisit(Args&&... args, F&& f); ```
```c++ template<class... args,="" class="" f=""> bool emplace_or_visit(Args&amp;&amp;... args, F&amp;&amp; f); template<class... args,="" class="" f=""> bool emplace_or_cvisit(Args&amp;&amp;... args, F&amp;&amp; f); ```</class...></class...>
Inserts an object, constructed with the arguments `args`, in the table if there is no element in the table with an equivalent key. Otherwise, invokes `f` with a const reference to the equivalent element.
若哈希表中不存在键等价的元素，则使用参数 `args` 构造对象并插入表中；否则，以该等价元素的常量引用为参数调用函数 `f`。
Requires:;; `value_type` is constructible from `args`. Returns:;; `true` if an insert took place. Concurrency:;; Blocking on rehashing of `*this`. Notes:;; The interface is exposition only, as C++ does not allow to declare a parameter `f` after a variadic parameter pack.
要求：;; `value_type` 可由 `args` 构造。
返回值：;; 若成功插入元素则返回 `true`。
并发特性：;; 会阻塞当前对象 `*this` 的扩容重哈希操作。
注意：;; 该接口仅为说明性用法，因为 C++ 不允许在可变参数包之后声明参数 `f`。

Visitation functions executed by a `boost::concurrent_node_set` `x` are not allowed to invoke any operation on `x`; invoking operations on a different `boost::concurrent_node_set` instance `y` is allowed only if concurrent outstanding operations on `y` do not access `x` directly or indirectly.
由 `boost::concurrent++_++node++_++set` `x` 执行的访问函数不得调用 `x` 上的任何操作；仅当对另一 `boost::concurrent++_++node++_++set` 实例 `y` 的并发未完成操作不直接或间接访问 `x` 时，才允许调用 `y` 上的操作。

In debug builds (more precisely, when link:../../../../../assert/doc/html/assert.html#boost_assert_is_void[`BOOST_ASSERT_IS_VOID`^] is not defined), __container reentrancies__ (illegaly invoking an operation on `m` from within a function visiting elements of `m`) are detected and signalled through `BOOST_ASSERT_MSG`. When run-time speed is a concern, the feature can be disabled by globally defining this macro.
在调试版本中（更准确地说，当未定义 link:../../../../../assert/doc/html/assert.html#boost_assert_is_void[`BOOST++_++ASSERT++_++IS++_++VOID`] 时），系统会检测__容器重入__行为（即在访问 `m` 元素的函数内部非法调用 `m` 上的操作），并通过 `BOOST++_++ASSERT++_++MSG` 发出信号。若需关注运行时速度，可通过全局定义此宏来禁用该功能。
Globally define this macro to enable xref:reference/stats.adoc#stats[statistics calculation] for the table. Note that this option decreases the overall performance of many operations.
全局定义此宏以启用容器的 xref:reference/stats.adoc#stats[统计计算] 功能。请注意，此选项会降低多数操作的总体性能。

Concurrency:;; Blocking on rehashing of `*this`. Notes:;; These overloads only participate 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.
