Detailed Description

Macro Definition Documentation

#define RAPIDJSON_ERROR_CHARTYPE   char

Character type of error messages.

The default character type is char. On Windows, user can define this macro as TCHAR for supporting both unicode/non-unicode settings.

Definition at line 39 of file error.h.

#define RAPIDJSON_ERROR_STRING (   x)    x

Macro for converting string literial to RAPIDJSON_ERROR_CHARTYPE[].

By default this conversion macro does nothing. On Windows, user can define this macro as _T(x) for supporting both unicode/non-unicode settings.

Definition at line 52 of file error.h.

#define RAPIDJSON_PARSE_ERROR (   parseErrorCode,
  offset 
)

(Internal) macro to indicate and handle a parse error.

Parameters
parseErrorCoderapidjson::ParseErrorCode of the error
offsetposition of the error in JSON input (size_t)

Invokes RAPIDJSON_PARSE_ERROR_NORETURN and stops the parsing.

See also
RAPIDJSON_PARSE_ERROR_NORETURN

Definition at line 120 of file reader.h.

#define RAPIDJSON_PARSE_ERROR_NORETURN (   parseErrorCode,
  offset 
)
Value:
RAPIDJSON_ASSERT(!HasParseError()); /* Error can only be assigned once */ \
SetParseError(parseErrorCode, offset); \
RAPIDJSON_MULTILINEMACRO_END
#define RAPIDJSON_ASSERT(x)
Assertion.
Definition: rapidjson.h:411

Macro to indicate a parse error.

Parameters
parseErrorCoderapidjson::ParseErrorCode of the error
offsetposition of the error in JSON input (size_t)

This macros can be used as a customization point for the internal error handling mechanism of RapidJSON.

A common usage model is to throw an exception instead of requiring the caller to explicitly check the rapidjson::GenericReader::Parse's return value:

1 #define RAPIDJSON_PARSE_ERROR_NORETURN(parseErrorCode,offset) \
2  throw ParseException(parseErrorCode, #parseErrorCode, offset)
3 
4 #include <stdexcept> // std::runtime_error
5 #include "rapidjson/error/error.h" // rapidjson::ParseResult
6 
7 struct ParseException : std::runtime_error, rapidjson::ParseResult {
8  ParseException(rapidjson::ParseErrorCode code, const char* msg, size_t offset)
9  : std::runtime_error(msg), ParseResult(code, offset) {}
10 };
11 
12 #include "rapidjson/reader.h"

Typedef Documentation

typedef const RAPIDJSON_ERROR_CHARTYPE*(* GetParseErrorFunc) (ParseErrorCode)

Function pointer type of GetParseError().

This is the prototype for GetParseError_X(), where X is a locale. User can dynamically change locale in runtime, e.g.:

1 GetParseErrorFunc GetParseError = GetParseError_En; // or whatever
2 const RAPIDJSON_ERROR_CHARTYPE* s = GetParseError(document.GetParseErrorCode());

Definition at line 153 of file error.h.

kParseErrorObjectMissColon 

Missing a colon after a name of object member.

kParseErrorObjectMissCommaOrCurlyBracket 

Missing a comma or '}' after an object member.

kParseErrorArrayMissCommaOrSquareBracket 

Missing a comma or ']' after an array element.

kParseErrorStringUnicodeEscapeInvalidHex 

Incorrect hex digit after \u escape in string.

kParseErrorStringUnicodeSurrogateInvalid 

The surrogate pair in string is invalid.

kParseErrorStringEscapeInvalid 

Invalid escape character in string.

kParseErrorStringMissQuotationMark 

Missing a closing quotation mark in string.

kParseErrorStringInvalidEncoding

kParseErrorNumberMissFraction 

Miss fraction part in number.

kParseErrorNumberMissExponent

Enumerator
kPointerParseErrorNone 

The parse is successful.

kPointerParseErrorTokenMustBeginWithSolidus 

A token must begin with a '/'.

kPointerParseErrorInvalidEscape 

Invalid escape.

kPointerParseErrorInvalidPercentEncoding 

Invalid percent encoding in URI fragment.

kPointerParseErrorCharacterMustPercentEncode

Function Documentation

RAPIDJSON_NAMESPACE_BEGIN const RAPIDJSON_ERROR_CHARTYPE* GetParseError_En ( ParseErrorCode  parseErrorCode)
inline

Maps error code of parsing into error message.

Parameters
parseErrorCodeError code obtained in parsing.
Returns
the error message.
Note
User can make a copy of this function for localization. Using switch-case is safer for future modification of error codes.

Definition at line 36 of file en.h.
