tool_generator_backend::__construct	(		$size,
			$fixeddataset = false,
			$filesizelimit = false,
			$progress = true
	)

Generic generator class.

Parameters

int	$size	Size as numeric index
bool	$fixeddataset	To use fixed or random data
int | bool	$filesizelimit	The max number of bytes for a generated file
bool	$progress	True if progress information should be displayed

Exceptions

Member Function Documentation

dot()

tool_generator_backend::dot (   $number,   $total  )

protected

Outputs dots.

There is up to one dot per second. Once a minute, it displays a percentage.

Parameters

int	$number	Number of completed items
int	$total	Total number of items to complete

log()

tool_generator_backend::log (   $langstring,   $a = null,   $leaveopen = false  )

protected

Displays information as part of progress.

Parameters

string	$langstring	Part of langstring (after progress_)
mixed	$a	Optional lang string parameters
bool	$leaveopen	If true, doesn't close LI tag (ready for dots)

size_for_name()

static tool_generator_backend::size_for_name (   $sizename )

static

Converts a size name into the numeric constant.

Parameters

string

$sizename

Size name e.g. 'L'

Return values

int	Numeric version

Exceptions

coding_exception

If the size name is not known
