Member Function Documentation

Value_Complex * JAULA::Parser::parseStream	(	std::istream &	inpStream,
		bool	comments_allowed = false,
		bool	full_read = true
	)		throw (Exception) [static]

Parses JSON data from a stream.

Parameters:

inpStream	stream from where to read the data to parse.
comments_allowed	flag that if it is true means that the input can contain comments that begin with the hash '#' symbol and ends with eoln (as in bash). If it is false, it means that no comments are allowed in the input and if present will be considered as a syntax error.
full_read	flag that if it is true means that the parser must analyze the input stream until the end of file is although it already had got a full array or object from it. In this situation, as JSON specification expects just only one array or object per input, any further data that is not a space for the syntax (or a comment if comments are allowed) will launch a syntax error exception.

If this flag is false, the parser will stop once a full array or object is taken from the input and, on exit, the stream will point to the start of the remaining data.

Returns:

a pointer to memory taken from the heap containing a complex value (array or object) with all the data from the stream parsed on individual / nested items.

Exceptions:

Exception

An exception will be thrown as soon as a lexical or syntax error is found analyzing the stream. The result of printing the exception through a stream is a human readable text explaining the error found and an approximation of the error line where occurred.

Description

This method is the entry point for the JSON parser.

Warning:

As this method returns a pointer to memory from the heap, it is up to the user to free it when it is no longer needed in order to avoid leaks.
