std::string Json::Reader::getFormatedErrorMessages ( ) const

Returns a user friendly string that list errors in the parsed document.

Returns: Formatted error message with the list of errors with their location in the parsed document. An empty string is returned if no error occurred during parsing.

Deprecated:: Use getFormattedErrorMessages() instead (typo fix).

bool Json::Reader::parse	(	const std::string &	document,
		Value &	root,
		bool	collectComments = `true`
	)

Read a Value from a JSON document.

Parameters

document	UTF-8 encoded string containing the document to read.
root	[out] Contains the root value of the document if it was successfully parsed.
collectComments	`true` to collect comment and allow writing them back during serialization, `false` to discard comments. This parameter is ignored if Features::allowComments_ is `false`.

Returns: true if the document was successfully parsed, false if an error occurred.

Definition at line 283 of file jsoncpp.cpp.

bool Json::Reader::parse	(	const char *	beginDoc,
		const char *	endDoc,
		Value &	root,
		bool	collectComments = `true`
	)

Read a Value from a JSON document.

Parameters

beginDoc	Pointer on the beginning of the UTF-8 encoded string of the document to read.
endDoc	Pointer on the end of the UTF-8 encoded string of the document to read. \ Must be >= beginDoc.
root	[out] Contains the root value of the document if it was successfully parsed.
collectComments	`true` to collect comment and allow writing them back during serialization, `false` to discard comments. This parameter is ignored if Features::allowComments_ is `false`.

Returns: true if the document was successfully parsed, false if an error occurred.

bool Json::Reader::parse	(	std::istream &	is,
		Value &	root,
		bool	collectComments = `true`
