Public Types
typedef bool(ParseResult::*)	BooleanType() const
	! Unspecified boolean type

Public Member Functions
	ParseResult ()
	Default constructor, no error.
	ParseResult (ParseErrorCode code, size_t offset)
	Constructor to set an error.
ParseErrorCode	Code () const
	Get the error code.
size_t	Offset () const
	Get the error offset, if IsError(), 0 otherwise.
	operator BooleanType () const
	Explicit conversion to bool, returns true, iff !IsError().
bool	IsError () const
	Whether the result is an error.
bool	operator== (const ParseResult &that) const
bool	operator== (ParseErrorCode code) const
bool	operator!= (const ParseResult &that) const
bool	operator!= (ParseErrorCode code) const
void	Clear ()
	Reset error code.
void	Set (ParseErrorCode code, size_t offset=0)
	Update error code and offset.

Detailed Description

Document doc;
ParseResult ok = doc.Parse("[42]");
if (!ok) {
    fprintf(stderr, "JSON parse error: %s (%u)",
            GetParseError_En(ok.Code()), ok.Offset());
    exit(EXIT_FAILURE);
