class  StaticString
 Lightweight wrapper to tag static string. More...

Function Documentation

static std::string Json::codePointToUTF8 ( unsigned int  cp) [inline, static]

Converts a unicode code-point to UTF-8.

Definition at line 101 of file jsoncpp.cpp.

static bool Json::containsControlCharacter ( const char *  str) [static]

Definition at line 3407 of file jsoncpp.cpp.

static bool Json::containsNewLine ( Reader::Location  begin,
Reader::Location  end 
) [static]

Definition at line 257 of file jsoncpp.cpp.

static char* Json::duplicateStringValue ( const char *  value,
unsigned int  length = unknown 
) [inline, static]

Duplicates the specified string value.

Parameters:
valuePointer to the string to duplicate. Must be zero-terminated if length is "unknown".
lengthLength of the value. if equals to unknown, then it will be computed using strlen(value).
Returns:
Pointer on the duplicate instance of string.

) [inline, static]

Definition at line 250 of file jsoncpp.cpp.

static bool Json::isControlCharacter ( char  ch) [inline, static]

Returns true if ch is a control character (in range [0,32[).

Definition at line 140 of file jsoncpp.cpp.

std::ostream & Json::operator<< ( std::ostream &  sout,
const Value &  root 
)

Output using the StyledStreamWriter.

See also:
Json::operator>>()

Definition at line 4213 of file jsoncpp.cpp.

std::istream & Json::operator>> ( std::istream &  sin,
Value &  root 
)

Read from 'sin' into 'root'.

Always keep comments from the input JSON.

This can be used to read a file into a particular sub-object. For example:

    Json::Value root;
    cin >> root["dir"]["file"];
    cout << root;

Result:

    {
    "dir": {
        "file": {
        // The input stream JSON would be nested here.
        }
    }
    }
    
Exceptions:
std::exceptionon parse error.

static void Json::uintToString ( LargestUInt  value,
char *&  current 
) [inline, static]

Converts an unsigned integer to string.

Parameters:
valueUnsigned interger to convert to string
currentInput/Output string buffer. Must have at least uintToStringBufferSize chars free.
