## 详细描述

main RapidJSON namespace

参见
  RAPIDJSON_NAMESPACE

## 类型定义说明

## SizeType

typedef unsigned rapidjson::SizeType

Size type (for string lengths, array sizes, etc.)

RapidJSON uses 32-bit array/string indices even on 64-bit platforms, instead of using `size_t`. Users may override the SizeType by defining RAPIDJSON_NO_SIZETYPEDEFINE.

## 枚举类型说明

## ParseFlag

enum rapidjson::ParseFlag

Combination of parseFlags

参见
  Reader::Parse, Document::Parse, Document::ParseInsitu, Document::ParseStream

枚举值
kParseNoFlags | No flags are set.
kParseInsituFlag | In-situ(destructive) parsing.
kParseValidateEncodingFlag | Validate encoding of JSON strings.
kParseIterativeFlag | Iterative(constant complexity in terms of function call stack size) parsing.
kParseStopWhenDoneFlag | After parsing a complete JSON root from stream, stop further processing the rest of stream. When this flag is used, parser will not generate kParseErrorDocumentRootNotSingular error.
kParseFullPrecisionFlag | Parse number in full precision (but slower).
kParseCommentsFlag | Allow one-line (//) and multi-line (/‍**/) comments.
kParseNumbersAsStringsFlag | Parse all numbers (ints/doubles) as strings.
kParseTrailingCommasFlag | Allow trailing commas at the end of objects and arrays.
kParseNanAndInfFlag | Allow parsing NaN, Inf, Infinity, -Inf and -Infinity as doubles.
kParseDefaultFlags | Default parse flags. Can be customized by defining RAPIDJSON_PARSE_DEFAULT_FLAGS

## PrettyFormatOptions

enum rapidjson::PrettyFormatOptions

Combination of PrettyWriter format flags.

参见
  PrettyWriter::SetFormatOptions

枚举值
kFormatDefault | Default pretty formatting.
kFormatSingleLineArray | Format arrays on a single line.

## Type

enum rapidjson::Type

Type of JSON value

枚举值
kNullType | null
kFalseType | false
kTrueType | true
kObjectType | object
kArrayType | array
kStringType | string
kNumberType | number

## UTFType

enum rapidjson::UTFType

Runtime-specified UTF encoding type of a stream.

枚举值
kUTF8 | UTF-8.
kUTF16LE | UTF-16 little endian.
kUTF16BE | UTF-16 big endian.
kUTF32LE | UTF-32 little endian.
kUTF32BE | UTF-32 big endian.

## WriteFlag

enum rapidjson::WriteFlag

Combination of writeFlags

枚举值
kWriteNoFlags | No flags are set.
kWriteValidateEncodingFlag | Validate encoding of JSON strings.
kWriteNanAndInfFlag | Allow writing of Infinity, -Infinity and NaN.
kWriteDefaultFlags | Default write flags. Can be customized by defining RAPIDJSON_WRITE_DEFAULT_FLAGS

## 函数说明

## SkipWhitespace()

template<typename InputStream >

void rapidjson::SkipWhitespace | ( | InputStream & | is | ) |

Skip the JSON white spaces in a stream.

参数

  is | A input stream for skipping white spaces.

注解
  This function has SSE2/SSE4.2 specialization.

## StringRef() [1/3]

template<typename CharType >

GenericStringRef< CharType > StringRef | ( | const CharType * | str | ) |

inline

Mark a character pointer as constant string

Mark a plain character pointer as a "string literal". This function can be used to avoid copying a character string to be referenced as a value in a JSON GenericValue object, if the string's lifetime is known to be valid long enough.

模板参数

  CharType | Character type of the string

参数

  str | Constant string, lifetime assumed to be longer than the use of the string in e.g. a GenericValue

返回
  GenericStringRef string reference object

参见
  GenericValue::GenericValue(StringRefType), GenericValue::operator=(StringRefType), GenericValue::SetString(StringRefType), GenericValue::PushBack(StringRefType, Allocator&), GenericValue::AddMember

## StringRef() [2/3]

template<typename CharType >

GenericStringRef< CharType > StringRef | ( | const CharType * | str,
|  | size_t | length
| ) |  |

inline

Mark a character pointer as constant string

Mark a plain character pointer as a "string literal". This function can be used to avoid copying a character string to be referenced as a value in a JSON GenericValue object, if the string's lifetime is known to be valid long enough.

This version has better performance with supplied length, and also supports string containing null characters.

模板参数

  CharType | character type of the string

参数

  str | Constant string, lifetime assumed to be longer than the use of the string in e.g. a GenericValue
  length | The length of source string.

返回
  GenericStringRef string reference object

## StringRef() [3/3]

template<typename CharType >

GenericStringRef< CharType > StringRef | ( | const std::basic_string< CharType > & | str | ) |

inline

Mark a string object as constant string

Mark a string object (e.g. `std::string`) as a "string literal". This function can be used to avoid copying a string to be referenced as a value in a JSON GenericValue object, if the string's lifetime is known to be valid long enough.

模板参数

  CharType | character type of the string

参数

  str | Constant string, lifetime assumed to be longer than the use of the string in e.g. a GenericValue

返回
  GenericStringRef string reference object

注解
  Requires the definition of the preprocessor symbol RAPIDJSON_HAS_STDSTRING.
