description()

static imscc1_converter::description ( )

static

Returns the basic information about the converter.

The returned array must contain the following keys: 'from' - the supported source format, eg. backup::FORMAT_MOODLE1 'to' - the supported target format, eg. backup::FORMAT_MOODLE 'cost' - the cost of the conversion, non-negative non-zero integer

Reimplemented from base_converter.

destroy()

base_converter::destroy ( )

protectedinherited

Cleans up stuff after the execution.

Note that we do not know if the execution was successful or not. An exception might have been thrown.

detect_format()

static imscc1_converter::detect_format (   $tempdir )

static

Detects the Common Cartridge 1.0 format of the backup directory.

Parameters

string

$tempdir

the name of the backup directory

Return values

null|string

backup::FORMAT_IMSCC1 if the Common Cartridge 1.0 is detected, null otherwise

Reimplemented from base_converter.

execute()

imscc1_converter::execute ( )

protected

Converts the contents of the tempdir into the target format in the workdir.

Reimplemented from base_converter.

get_id()

base_converter::get_id ( )

inherited

Get instance identifier.

Return values

string

the unique identifier of this converter instance

get_name()

base_converter::get_name ( )

inherited

Get converter name.

Return values

string

the system name of the converter

get_tempdir_path()

base_converter::get_tempdir_path ( )

inherited

Return values

string

the full path to the directory with the source backup

get_workdir_path()

base_converter::get_workdir_path ( )

inherited

Return values

string

the full path to the working directory

init()

base_converter::init ( )

protectedinherited

end of public API //////////////////////////////////////////////////////

Initialize the instance if needed, called by the constructor

Reimplemented in moodle1_converter.

is_available()

static base_converter::is_available ( )

staticinherited

public static methods //////////////////////////////////////////////////

Makes sure that this converter is available at this site

This is intended for eventual PHP extensions check, environment check etc. All checks that do not depend on actual backup data should be done here.

Return values

boolean

true if this converter should be considered as available

Reimplemented in imscc1_export_converter, and moodle1_export_converter.

log()

imscc1_converter::log	(		$message,
			$level,
			$a = null,
			$depth = null,
			$display = false
	)

This function will be responsible for handling the params, and to call to the corresponding logger->process() once all modifications in params have been performed.

Reimplemented from base_converter.

replace_tempdir()

base_converter::replace_tempdir ( )

protectedinherited

Replaces the source backup directory with the converted version.

If $CFG->keeptempdirectoriesonbackup is defined, the original source source backup directory is kept for debugging purposes.

set_logger()

base_converter::set_logger (   $logger )
