# rapidjson.natvis
This file can be used as a [Visual Studio Visualizer](https://docs.microsoft.com/en-gb/visualstudio/debugger/create-custom-views-of-native-objects) to aid in visualizing rapidjson structures within the Visual Studio debugger. Natvis visualizers are supported in Visual Studio 2012 and later. To install, copy the file into this directory:
`%USERPROFILE%\Documents\Visual Studio 2012\Visualizers`
Each version of Visual Studio has a similar directory, it must be copied into each directory to be used with that particular version. In Visual Studio 2015 and later, this can be done without restarting Visual Studio (a new debugging session must be started).

In the SAX API, `Reader` consumes memory portional to maximum depth of JSON tree, plus maximum length of JSON string.
In the SAX API, `Reader` consumes memory proportional to maximum depth of JSON tree, plus maximum length of JSON string.
In the DOM API, each `Value` consumes exactly 16/24 bytes for 32/64-bit architecture respectively. RapidJSON also uses a special memory allocator to minimize overhead of allocations.
5. What is the purpose of being high performance?
Some applications need to process very large JSON files. Some server-side applications need to process huge amount of JSONs. Being high performance can improve both latency and throuput. In a broad sense, it will also save energy.

# 内部架构
本部分记录了一些设计和实现细节。
[TOC]
# 架构 {#Architecture}
## SAX 和 DOM
下面的 UML 图显示了 SAX 和 DOM 的基本关系。
![架构 UML 类图](diagram/architecture.png)
关系的核心是 `Handler` 概念。在 SAX 一边,`Reader` 从流解析 JSON 并将事件发送到 `Handler`。`Writer` 实现了 `Handler` 概念,用于处理相同的事件。在 DOM 一边,`Document` 实现了 `Handler` 概念,用于通过这些时间来构建 DOM。`Value` 支持了 `Value::Accept(Handler&)` 函数,它可以将 DOM 转换为事件进行发送。
在这个设计SAX 是不依赖于 DOM 的。甚至 `Reader``Writer` 之间也没有依赖。这提供了连接事件发送器和处理器的灵活性。除此之外,`Value` 也是不依赖于 SAX 的。所以,除了将 DOM 序列化为 JSON 之外,用户也可以将其序列化为 XML或者做任何其他事情。
## 工具类
SAX 和 DOM API 都依赖于3个额外的概念`Allocator`、`Encoding` 和 `Stream`。它们的继承层次结构如下图所示。
![工具类 UML 类图](diagram/utilityclass.png)
# 值Value {#Value}
`Value` (实际上被定义为 `GenericValue<UTF8<>>`)是 DOM API 的核心。本部分描述了它的设计。
## 数据布局 {#DataLayout}
`Value` 是[可变类型](http://en.wikipedia.org/wiki/Variant_type)。在 RapidJSON 的上下文中,一个 `Value` 的实例可以包含6种 JSON 数据类型之一。通过使用 `union` ,这是可能实现的。每一个 `Value` 包含两个成员:`union Data data_` 和 `unsigned flags_`。`flags_` 表明了 JSON 类型,以及附加的信息。
下表显示了所有类型的数据布局。32位/64位列表明了字段所占用的字节数。

| (未使用) | |4 |8 |
| `unsigned flags_` |`kNumberType kNumberFlag kDoubleFlag`|4 |4 |
这里有一些需要注意的地方:
* 为了减少在64位架构上的内存消耗`SizeType` 被定义为 `unsigned` 而不是 `size_t`
* 32位整数的零填充可能被放在实际类型的前面或后面这依赖于字节序。这使得它可以将32位整数不经过任何转换就可以解释为64位整数。
* `Int` 永远是 `Int64`,反之不然。
## 标志 {#Flags}
32位的 `flags_` 包含了 JSON 类型和其他信息。如前文中的表所述,每一种 JSON 类型包含了冗余的 `kXXXType``kXXXFlag`。这个设计是为了优化测试位标志(`IsNumber()`)和获取每一种类型的序列号(`GetType()`)。
字符串有两个可选的标志。`kCopyFlag` 表明这个字符串拥有字符串拷贝的所有权。而 `kInlineStrFlag` 意味着使用了[短字符串优化](#ShortString)。
数字更加复杂一些。对于普通的整数值,它可以包含 `kIntFlag`、`kUintFlag`、 `kInt64Flag` 和/或 `kUint64Flag`这由整数的范围决定。带有小数或者超过64位所能表达的范围的整数的数字会被存储为带有 `kDoubleFlag``double`
## 短字符串优化 {#ShortString}
[Kosta](https://github.com/Kosta-Github) 提供了很棒的短字符串优化。这个优化的xxx如下所述。除去 `flags_` `Value` 有12或16字节对于32位或64位来存储实际的数据。这为在其内部直接存储短字符串而不是存储字符串的指针创造了可能。对于1字节的字符类型例如 `char`),它可以在 `Value` 类型内部存储至多11或15个字符的字符串。
|ShortString (Ch=char)| | 32位 | 64位 |
|---------------------|-------------------------------------|:----:|:----:|
| `Ch str[MaxChars]` | 字符串缓冲区 |11 |15 |
| `Ch invLength` | MaxChars - Length |1 |1 |
| `unsigned flags_` | `kStringType kStringFlag ...` |4 |4 |
这里使用了一项特殊的技术。它存储了 (MaxChars - length) 而不直接存储字符串的长度。这使得存储11个字符并且带有后缀 `\0` 成为可能。
这个优化可以减少字符串拷贝内存占用。它也改善了缓存一致性,并进一步提高了运行时性能。
# 分配器Allocator {#InternalAllocator}
`Allocator` 是 RapidJSON 中的概念:
~~~cpp
concept Allocator {
static const bool kNeedFree; //!< 表明这个分配器是否需要调用 Free()
// 申请内存块。
// \param size 内存块的大小,以字节记。
// \returns 指向内存块的指针。
void* Malloc(size_t size);
// 调整内存块的大小。
// \param originalPtr 当前内存块的指针。空指针是被允许的。
// \param originalSize 当前大小,以字节记。(设计问题:因为有些分配器可能不会记录它,显示的传递它可以节约内存。)
// \param newSize 新大小,以字节记。
void* Realloc(void* originalPtr, size_t originalSize, size_t newSize);
// 释放内存块。
// \param ptr 指向内存块的指针。空指针是被允许的。
static void Free(void *ptr);
};
~~~
需要注意的是 `Malloc()``Realloc()` 是成员函数而 `Free()` 是静态成员函数。
## MemoryPoolAllocator {#MemoryPoolAllocator}
`MemoryPoolAllocator` 是 DOM 的默认内存分配器。它只申请内存而不释放内存。这对于构建 DOM 树非常合适。
在它的内部,它从基础的内存分配器申请内存块(默认为 `CrtAllocator`)并将这些内存块存储为单向链表。当用户请求申请内存,它会遵循下列步骤来申请内存:
1. 如果可用,使用用户提供的缓冲区。(见 [User Buffer section in DOM](doc/dom.md)
2. 如果用户提供的缓冲区已满,使用当前内存块。
3. 如果当前内存块已满,申请新的内存块。
# 解析优化 {#ParsingOptimization}
## 使用 SIMD 跳过空格 {#SkipwhitespaceWithSIMD}
当从流中解析 JSON 时解析器需要跳过4种空格字符
1. 空格 (`U+0020`)
2. 制表符 (`U+000B`)
3. 换行 (`U+000A`)
4. 回车 (`U+000D`)
这是一份简单的实现:
~~~cpp
void SkipWhitespace(InputStream& s) {
while (s.Peek() == ' ' || s.Peek() == '\n' || s.Peek() == '\r' || s.Peek() == '\t')
s.Take();
}
~~~
但是这需要对每个字符进行4次比较以及一些分支。这被发现是一个热点。
为了加速这一处理RapidJSON 使用 SIMD 来在一次迭代中比较16个字符和4个空格。目前 RapidJSON 支持 SSE2 SSE4.2 和 ARM Neon 指令。同时它也只会对 UTF-8 内存流启用,包括字符串流或 *原位* 解析。
你可以通过在包含 `rapidjson.h` 之前定义 `RAPIDJSON_SSE2` `RAPIDJSON_SSE42``RAPIDJSON_NEON` 来启用这个优化。一些编译器可以检测这个设置,如 `perftest.h`
~~~cpp
// __SSE2____SSE4_2__ 可被 gcc、clang 和 Intel 编译器识别:
// 如果支持的话,我们在 gmake 中使用了 -march=native 来启用 -msse2 和 -msse4.2
// 同样的, __ARM_NEON 被用于识别Neon
#if defined(__SSE4_2__)
# define RAPIDJSON_SSE42
#elif defined(__SSE2__)
# define RAPIDJSON_SSE2
#elif defined(__ARM_NEON)
# define RAPIDJSON_NEON
#endif
~~~
需要注意的是,这是编译期的设置。在不支持这些指令的机器上运行可执行文件会使它崩溃。
### 页面对齐问题
在 RapidJSON 的早期版本中,被报告了[一个问题](https://code.google.com/archive/p/rapidjson/issues/104)`SkipWhitespace_SIMD()` 会罕见地导致崩溃(约五十万分之一的几率)。在调查之后,怀疑是 `_mm_loadu_si128()` 访问了 `'\0'` 之后的内存,并越过被保护的页面边界。
在 [Intel® 64 and IA-32 Architectures Optimization Reference Manual
](http://www.intel.com/content/www/us/en/architecture-and-technology/64-ia-32-architectures-optimization-manual.html) 中,章节 10.2.1
> 为了支持需要费对齐的128位 SIMD 内存访问的算法调用者的内存缓冲区申请应当考虑添加一些填充空间这样被调用的函数可以安全地将地址指针用于未对齐的128位 SIMD 内存操作。
> 在结合非对齐的 SIMD 内存操作中,最小的对齐大小应该等于 SIMD 寄存器的大小。
对于 RapidJSON 来说,这显然是不可行的,因为 RapidJSON 不应当强迫用户进行内存对齐。
为了修复这个问题,当前的代码会先按字节处理直到下一个对齐的地址。在这之后,使用对齐读取来进行 SIMD 处理。见 [#85](https://github.com/Tencent/rapidjson/issues/85)。
## 局部流拷贝 {#LocalStreamCopy}
在优化的过程中,我们发现一些编译器不能将访问流的一些成员数据放入局部变量或者寄存器中。测试结果显示,对于一些流类型,创建流的拷贝并将其用于内层循环中可以改善性能。例如,实际(非 SIMD`SkipWhitespace()` 被实现为:
~~~cpp
template<typename InputStream>
void SkipWhitespace(InputStream& is) {
internal::StreamLocalCopy<InputStream> copy(is);
InputStream& s(copy.s);
while (s.Peek() == ' ' || s.Peek() == '\n' || s.Peek() == '\r' || s.Peek() == '\t')
s.Take();
}
~~~
基于流的特征,`StreamLocalCopy` 会创建(或不创建)流对象的拷贝,在局部使用它并将流的状态拷贝回原来的流。
## 解析为双精度浮点数 {#ParsingDouble}
将字符串解析为 `double` 并不简单。标准库函数 `strtod()` 可以胜任这项工作,但它比较缓慢。默认情况下,解析器使用默认的精度设置。这最多有 3[ULP](http://en.wikipedia.org/wiki/Unit_in_the_last_place) 的误差,并实现在 `internal::StrtodNormalPrecision()` 中。
当使用 `kParseFullPrecisionFlag` 时,编译器会改为调用 `internal::StrtodFullPrecision()` ,这个函数会自动调用三个版本的转换。
1. [Fast-Path](http://www.exploringbinary.com/fast-path-decimal-to-floating-point-conversion/)。
2. [double-conversion](https://github.com/floitsch/double-conversion) 中的自定义 DIY-FP 实现。
3. Clinger, William D. How to read floating point numbers accurately. Vol. 25. No. 6. ACM, 1990 中的大整数算法。
如果第一个转换方法失败,则尝试使用第二种方法,以此类推。
# 生成优化 {#GenerationOptimization}
## 整数到字符串的转换 {#itoa}
整数到字符串转换的朴素算法需要对每一个十进制位进行一次除法。我们实现了若干版本并在 [itoa-benchmark](https://github.com/miloyip/itoa-benchmark) 中对它们进行了评估。
虽然 SSE2 版本是最快的,但它和第二快的 `branchlut` 差距不大。而且 `branchlut` 是纯C++实现,所以我们在 RapidJSON 中使用了 `branchlut`
## 双精度浮点数到字符串的转换 {#dtoa}
原来 RapidJSON 使用 `snprintf(..., ..., "%g")` 来进行双精度浮点数到字符串的转换。这是不准确的因为默认的精度是6。随后我们发现它很缓慢而且有其它的替代品。
Google 的 V8 [double-conversion](https://github.com/floitsch/double-conversion
) 实现了更新的、快速的被称为 Grisu3 的算法Loitsch, Florian. "Printing floating-point numbers quickly and accurately with integers." ACM Sigplan Notices 45.6 (2010): 233-243.)。
然而,这个实现不是仅头文件的,所以我们实现了一个仅头文件的 Grisu2 版本。这个算法保证了结果永远精确。而且在大多数情况下,它会生成最短的(可选)字符串表示。
这个仅头文件的转换函数在 [dtoa-benchmark](https://github.com/miloyip/dtoa-benchmark) 中进行评估。
# 解析器 {#Parser}
## 迭代解析 {#IterativeParser}
迭代解析器是一个以非递归方式实现的递归下降的 LL(1) 解析器。
### 语法 {#IterativeParserGrammar}
解析器使用的语法是基于严格 JSON 语法的:
~~~~~~~~~~
S -> array | object
array -> [ values ]
object -> { members }
values -> non-empty-values | ε
non-empty-values -> value addition-values
addition-values -> ε | , non-empty-values
members -> non-empty-members | ε
non-empty-members -> member addition-members
addition-members -> ε | , non-empty-members
member -> STRING : value
value -> STRING | NUMBER | NULL | BOOLEAN | object | array
~~~~~~~~~~
注意到左因子被加入了非终结符的 `values``members` 来保证语法是 LL(1) 的。
### 解析表 {#IterativeParserParsingTable}
基于这份语法,我们可以构造 FIRST 和 FOLLOW 集合。
非终结符的 FIRST 集合如下所示:
| NON-TERMINAL | FIRST |
|:-----------------:|:--------------------------------:|
| array | [ |
| object | { |
| values | ε STRING NUMBER NULL BOOLEAN { [ |
| addition-values | ε COMMA |
| members | ε STRING |
| addition-members | ε COMMA |
| member | STRING |
| value | STRING NUMBER NULL BOOLEAN { [ |
| S | [ { |
| non-empty-members | STRING |
| non-empty-values | STRING NUMBER NULL BOOLEAN { [ |
FOLLOW 集合如下所示:
| NON-TERMINAL | FOLLOW |
|:-----------------:|:-------:|
| S | $ |
| array | , $ } ] |
| object | , $ } ] |
| values | ] |
| non-empty-values | ] |
| addition-values | ] |
| members | } |
| non-empty-members | } |
| addition-members | } |
| member | , } |
| value | , } ] |
最终可以从 FIRST 和 FOLLOW 集合生成解析表:
| NON-TERMINAL | [ | { | , | : | ] | } | STRING | NUMBER | NULL | BOOLEAN |
|:-----------------:|:---------------------:|:---------------------:|:-------------------:|:-:|:-:|:-:|:-----------------------:|:---------------------:|:---------------------:|:---------------------:|
| S | array | object | | | | | | | | |
| array | [ values ] | | | | | | | | | |
| object | | { members } | | | | | | | | |
| values | non-empty-values | non-empty-values | | | ε | | non-empty-values | non-empty-values | non-empty-values | non-empty-values |
| non-empty-values | value addition-values | value addition-values | | | | | value addition-values | value addition-values | value addition-values | value addition-values |
| addition-values | | | , non-empty-values | | ε | | | | | |
| members | | | | | | ε | non-empty-members | | | |
| non-empty-members | | | | | | | member addition-members | | | |
| addition-members | | | , non-empty-members | | | ε | | | | |
| member | | | | | | | STRING : value | | | |
| value | array | object | | | | | STRING | NUMBER | NULL | BOOLEAN |
对于上面的语法分析,这里有一个很棒的[工具](http://hackingoff.com/compilers/predict-first-follow-set)。
### 实现 {#IterativeParserImplementation}
基于这份解析表,一个直接的(常规的)将规则反向入栈的实现可以正常工作。
在 RapidJSON 中,对直接的实现进行了一些修改:
首先,在 RapidJSON 中,这份解析表被编码为状态机。
规则由头部和主体组成。
状态转换由规则构造。
除此之外,额外的状态被添加到与 `array``object` 有关的规则。
通过这种方式,生成数组值或对象成员可以只用一次状态转移便可完成,
而不需要在直接的实现中的多次出栈/入栈操作。
这也使得估计栈的大小更加容易。
状态图如如下所示:
![状态图](diagram/iterative-parser-states-diagram.png)
第二,迭代解析器也在内部栈保存了数组的值个数和对象成员的数量,这也与传统的实现不同。

If `kParseNumbersAsStrings` is enabled, `Reader` will always calls `RawNumber()` instead.
`String(const char* str, SizeType length, bool copy)` is called when the `Reader` encounters a string. The first parameter is pointer to the string. The second parameter is the length of the string (excluding the null terminator). Note that RapidJSON supports null character `'\0'` inside a string. If such situation happens, `strlen(str) < length`. The last `copy` indicates whether the handler needs to make a copy of the string. For normal parsing, `copy = true`. Only when *insitu* parsing is used, `copy = false`. And beware that, the character type depends on the target encoding, which will be explained later.

Unlike most JSON Schema validator implementations, RapidJSON provides a SAX-based schema validator. Therefore, you can parse a JSON from a stream while validating it on the fly. If the validator encounters a JSON value that invalidates the supplied schema, the parsing will be terminated immediately. This design is especially useful for parsing large JSON files.

# Schema violation reporting {#Reporting}
(Unreleased as of 2017-09-20)
When validating an instance against a JSON Schema,
it is often desirable to report not only whether the instance is valid,
but also the ways in which it violates the schema.
The `SchemaValidator` class
collects errors encountered during validation
into a JSON `Value`.
This error object can then be accessed as `validator.GetError()`.
The structure of the error object is subject to change
in future versions of RapidJSON,
as there is no standard schema for violations.
The details below this point are provisional only.
## General provisions {#ReportingGeneral}
Validation of an instance value against a schema
produces an error value.
The error value is always an object.
An empty object `{}` indicates the instance is valid.
* The name of each member
corresponds to the JSON Schema keyword that is violated.
* The value is either an object describing a single violation,
or an array of such objects.
Each violation object contains two string-valued members
named `instanceRef` and `schemaRef`.
`instanceRef` contains the URI fragment serialization
of a JSON Pointer to the instance subobject
in which the violation was detected.
`schemaRef` contains the URI of the schema
and the fragment serialization of a JSON Pointer
to the subschema that was violated.
Individual violation objects can contain other keyword-specific members.
These are detailed further.
For example, validating this instance:
~~~json
{"numbers": [1, 2, "3", 4, 5]}
~~~
against this schema:
~~~json
{
"type": "object",
"properties": {
"numbers": {"$ref": "numbers.schema.json"}
}
}
~~~
where `numbers.schema.json` refers
(via a suitable `IRemoteSchemaDocumentProvider`)
to this schema:
~~~json
{
"type": "array",
"items": {"type": "number"}
}
~~~
produces the following error object:
~~~json
{
"type": {
"instanceRef": "#/numbers/2",
"schemaRef": "numbers.schema.json#/items",
"expected": ["number"],
"actual": "string"
}
}
~~~
## Validation keywords for numbers {#Numbers}
### multipleOf {#multipleof}
* `expected`: required number strictly greater than 0.
The value of the `multipleOf` keyword specified in the schema.
* `actual`: required number.
The instance value.
### maximum {#maximum}
* `expected`: required number.
The value of the `maximum` keyword specified in the schema.
* `exclusiveMaximum`: optional boolean.
This will be true if the schema specified `"exclusiveMaximum": true`,
and will be omitted otherwise.
* `actual`: required number.
The instance value.
### minimum {#minimum}
* `expected`: required number.
The value of the `minimum` keyword specified in the schema.
* `exclusiveMinimum`: optional boolean.
This will be true if the schema specified `"exclusiveMinimum": true`,
and will be omitted otherwise.
* `actual`: required number.
The instance value.
## Validation keywords for strings {#Strings}
### maxLength {#maxLength}
* `expected`: required number greater than or equal to 0.
The value of the `maxLength` keyword specified in the schema.
* `actual`: required string.
The instance value.
### minLength {#minLength}
* `expected`: required number greater than or equal to 0.
The value of the `minLength` keyword specified in the schema.
* `actual`: required string.
The instance value.
### pattern {#pattern}
* `actual`: required string.
The instance value.
(The expected pattern is not reported
because the internal representation in `SchemaDocument`
does not store the pattern in original string form.)
## Validation keywords for arrays {#Arrays}
### additionalItems {#additionalItems}
This keyword is reported
when the value of `items` schema keyword is an array,
the value of `additionalItems` is `false`,
and the instance is an array
with more items than specified in the `items` array.
* `disallowed`: required integer greater than or equal to 0.
The index of the first item that has no corresponding schema.
### maxItems and minItems {#maxItems-minItems}
* `expected`: required integer greater than or equal to 0.
The value of `maxItems` (respectively, `minItems`)
specified in the schema.
* `actual`: required integer greater than or equal to 0.
Number of items in the instance array.
### uniqueItems {#uniqueItems}
* `duplicates`: required array
whose items are integers greater than or equal to 0.
Indices of items of the instance that are equal.
(RapidJSON only reports the first two equal items,
for performance reasons.)
## Validation keywords for objects
### maxProperties and minProperties {#maxProperties-minProperties}
* `expected`: required integer greater than or equal to 0.
The value of `maxProperties` (respectively, `minProperties`)
specified in the schema.
* `actual`: required integer greater than or equal to 0.
Number of properties in the instance object.
### required {#required}
* `missing`: required array of one or more unique strings.
The names of properties
that are listed in the value of the `required` schema keyword
but not present in the instance object.
### additionalProperties {#additionalProperties}
This keyword is reported
when the schema specifies `additionalProperties: false`
and the name of a property of the instance is
neither listed in the `properties` keyword
nor matches any regular expression in the `patternProperties` keyword.
* `disallowed`: required string.
Name of the offending property of the instance.
(For performance reasons,
RapidJSON only reports the first such property encountered.)
### dependencies {#dependencies}
* `errors`: required object with one or more properties.
Names and values of its properties are described below.
Recall that JSON Schema Draft 04 supports
*schema dependencies*,
where presence of a named *controlling* property
requires the instance object to be valid against a subschema,
and *property dependencies*,
where presence of a controlling property
requires other *dependent* properties to be also present.
For a violated schema dependency,
`errors` will contain a property
with the name of the controlling property
and its value will be the error object
produced by validating the instance object
against the dependent schema.
For a violated property dependency,
`errors` will contain a property
with the name of the controlling property
and its value will be an array of one or more unique strings
listing the missing dependent properties.
## Validation keywords for any instance type {#AnyTypes}
### enum {#enum}
This keyword has no additional properties
beyond `instanceRef` and `schemaRef`.
* The allowed values are not listed
because `SchemaDocument` does not store them in original form.
* The violating value is not reported
because it might be unwieldy.
If you need to report these details to your users,
you can access the necessary information
by following `instanceRef` and `schemaRef`.
### type {#type}
* `expected`: required array of one or more unique strings,
each of which is one of the seven primitive types
defined by the JSON Schema Draft 04 Core specification.
Lists the types allowed by the `type` schema keyword.
* `actual`: required string, also one of seven primitive types.
The primitive type of the instance.
### allOf, anyOf, and oneOf {#allOf-anyOf-oneOf}
* `errors`: required array of at least one object.
There will be as many items as there are subschemas
in the `allOf`, `anyOf` or `oneOf` schema keyword, respectively.
Each item will be the error value
produced by validating the instance
against the corresponding subschema.
For `allOf`, at least one error value will be non-empty.
For `anyOf`, all error values will be non-empty.
For `oneOf`, either all error values will be non-empty,
or more than one will be empty.
### not {#not}
This keyword has no additional properties
apart from `instanceRef` and `schemaRef`.

有一些方案可避免实质地复制这些数据例如引用计数reference counting、垃圾回收garbage collection, GC
为了使 RapidJSON 简单及快速,我们选择了对赋值采用 * 转移 *。这方法与 `std::auto_ptr` 相似,都是在赋值时转移拥有权。转移快得多简单得多,只需要析构原来的 Value把来源 `memcpy()` 至目标,最后把来源设置为 Null 类型。

另外,上面的 `SetString()` 需要长度参数。这个 API 能处理含有空字符的字符串。另一个 `SetString()` 重载函数没有长度参数,它假设输入是空字符结尾的,并会调用类似 `strlen()` 的函数去获取长度。
最后,对于字符串字面量或有安全生命周期的字符串,可以使用 const-string 版本的 `SetString()`,它没有 allocator 参数。对于字符串家面量(或字符数组常量),只需简单地传递字面量,又安全又高效:

// This example demonstrates JSON token-by-token parsing with an API that is
// more direct; you don't need to design your logic around a handler object and
// callbacks. Instead, you retrieve values from the JSON stream by calling
// GetInt(), GetDouble(), GetString() and GetBool(), traverse into structures
// by calling EnterObject() and EnterArray(), and skip over unwanted data by
// calling SkipValue(). When you know your JSON's structure, this can be quite
// convenient.
//
// If you aren't sure of what's next in the JSON data, you can use PeekType() and
// PeekValue() to look ahead to the next object before reading it.
//
// If you call the wrong retrieval method--e.g. GetInt when the next JSON token is
// not an int, EnterObject or EnterArray when there isn't actually an object or array
// to read--the stream parsing will end immediately and no more data will be delivered.
//
// After calling EnterObject, you retrieve keys via NextObjectKey() and values via
// the normal getters. When NextObjectKey() returns null, you have exited the
// object, or you can call SkipObject() to skip to the end of the object
// immediately. If you fetch the entire object (i.e. NextObjectKey() returned null),
// you should not call SkipObject().
//
// After calling EnterArray(), you must alternate between calling NextArrayValue()
// to see if the array has more data, and then retrieving values via the normal
// getters. You can call SkipArray() to skip to the end of the array immediately.
// If you fetch the entire array (i.e. NextArrayValue() returned null),
// you should not call SkipArray().
//
// This parser uses in-situ strings, so the JSON buffer will be altered during the
