When a <<ref_value>> is formatted to a {std_ostream}, the result is serialized JSON as if by calling <<ref_serialize>>.
当将 &lt;<<ref_value>&gt;> 输出到 {std_ostream} 时，其结果等同于调用 &lt;<<ref_serialize>&gt;> 所生成的序列化 JSON。</ref_serialize></ref_value>

Functions returning {ref_result} allow you to use both approaches:

Translation changed
If the value's kind is known statically, a reference to the underlying representation may be obtained by dereferencing the pointer without checking. This avoids the code overhead of the possible exception when using, for example <<ref_value_as_string,`value::as_string`>>:
如果值的种类是静态已知的，则可以通过解引用指针而不检查来获取对底层表示形式的引用。这避免了使用例如&lt; <<ref_value_as_string,`value::as_string`>&gt;> 时可能出现的异常所带来的代码开销：</ref_value_as_string,`value::as_string`>

Translation changed
We can query a value for its underlying representation of a particular kind in a way that does not throw exceptions by requesting a pointer which may be null, instead of a reference. Here we use <<ref_value_if_string,`value::if_string`>> to conditionally perform an assignment without using exceptions:
我们可以通过请求一个可能为空的指针（而非引用）来查询值中特定种类的底层表示形式，而不会抛出异常。这里我们使用&lt; <<ref_value_if_string,`value::if_string`>&gt;> 来条件执行赋值操作，而无需使用异常：</ref_value_if_string,`value::if_string`>

Translation changed
However, as shown above these functions throw an exception if the kind in the <<ref_value>> does not match the kind denoted by the function signature. This can be used as a concise form of validation: access values as if they were the right type, but handle the resulting exception indicating if the schema of the JSON is not valid.
然而，如上所示，如果 &lt;<<ref_value>&gt;> 中的实际类型与函数签名所指定的类型不匹配，这些函数会抛出异常。这一行为可作为一种简洁的验证形式：以预期类型直接访问值，若 JSON 结构无效，则通过捕获异常进行处理。</ref_value>

Translation changed
If the <<ref_kind>> of a <<ref_value>> is known, functions such as <<ref_value_as_bool,`value::as_bool`>> or <<ref_value_as_string,`value::as_string`>> may be used to obtain a reference to the underlying representation without changing the existing value:
如果已知 &lt;<<ref_value>&gt; 的 &lt;> 的 <<ref_kind>&gt;>，可使用诸如 &lt;&gt; 或 &lt;&gt;<<ref_value_as_bool,`value::as_bool`>> 或 <<ref_value_as_string,`value::as_string`>> 等函数，在不改变现有值的情况下获取对底层表示的引用：</ref_kind></ref_value>

An associative array of string keys mapping to <<ref_value>> elements with an
interface similar to {std_unordered_map}, that remembers insertion order.
一个关联数组，其键为字符串，值为 &lt;<<ref_value>&gt;> 元素，接口类似于 {std_unordered_map}，并保留插入顺序。</ref_value>

Translation changed
The emplace members of <<ref_value>> return a typed reference to the underlying representation. For example, the call to <<ref_value_emplace_string,`value::emplace_string`>> in the previous example returns a <<ref_string,`string&`>>. This table shows the underlying type for each kind:
&lt;&lt;<<ref_value>&gt;> 的置入成员函数返回对底层表示形式的类型化引用。例如，前例中对 &lt;&gt; 的调用返回一个 &lt;&gt;<<ref_value_emplace_string,`value::emplace_string`>> 的调用返回一个 <<ref_string,`string&`>> 。下表列出了每种 kind 对应的底层类型：</ref_value>
