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:

value	Pointer to the string to duplicate. Must be zero-terminated if length is "unknown".
length	Length of the value. if equals to unknown, then it will be computed using strlen(value).

Returns:: Pointer on the duplicate instance of string.

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::exception on parse error.

Definition at line 1610 of file jsoncpp.cpp.

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

Converts an unsigned integer to string.

Parameters:

value	Unsigned interger to convert to string
current	Input/Output string buffer. Must have at least uintToStringBufferSize chars free.
