void casa::viewer::ds9parser::error	(	const class location &	l,
		const std::string &	m
	)

To demonstrate pure handling of parse errors, instead of simply dumping them on the standard error output, we will pass them to the driver using the following two member functions.

Error handling with associated line number. This can be modified to output the error e.g. to a dialog box.

void casa::viewer::ds9parser::error

(

const std::string &

m

)

General error handling.

This can be modified to output the error e.g. to a dialog box.

bool casa::viewer::ds9parser::parse_file	(	ds9context &	base,
		const std::string &	filename
	)

bool casa::viewer::ds9parser::parse_stream	(	ds9context &	base,
		std::istream &	in,
		const std::string &	sname = "stream input"
	)

input stream, stream name for error messages, return true if successfully parsed

bool casa::viewer::ds9parser::parse_string	(	ds9context &	base,
		const std::string &	input,
		const std::string &	sname = "string stream"
	)
