Detailed Description

• the format string follows printf style with
  • b : print bar with optional length, e.g. %30b for 30 characters
  • i : print progress indicator
  • p : print progress percentage
  • e : print time to finish (ETA)
  • t : print elapsed time
  • m : print current memory usage (if supported)
• if format == "", a default definition is used

TStreamProgressBar

(

const progress_charset_t

acharset = ascii_charset)

construct progress bar using std::cout output stream and standard output format

TStreamProgressBar	(	const std::string &	format,

	)

construct progress bar using std::cout output stream and output format as defined by format

TStreamProgressBar	(	std::ostream &	out_stream,
		const progress_charset_t	acharset = ascii_charset
	)

construct progress bar with output stream out_stream and standard output format
