Member Function Documentation

apply_config_defaults()

static backup_controller_dbops::apply_config_defaults ( backup_controller  $controller )

static

Sets the default values for the settings in a backup operation.

Based on the mode of the backup it will load proper defaults using apply_admin_config_defaults.

Parameters

backup_controller

$controller

backup_get_original_course_info()

static backup_controller_dbops::backup_get_original_course_info (   $courseid )

static

Given the courseid, return some course related information we want to transport.

Parameters

int

$course

the id of the course this backup belongs to

backup_includes_file_references()

static backup_controller_dbops::backup_includes_file_references (   $backupid )

static

Given the backupid, detect if the backup contains references to external contents.

Return values

int

backup_includes_files()

static backup_controller_dbops::backup_includes_files (   $backupid )

static

Given the backupid, determine whether this backup should include files from the moodle file storage system.

Parameters

string

$backupid

The ID of the backup.

Return values

int	Indicates whether files should be included in backups.

decode_backup_temp_info()

static backup_controller_dbops::decode_backup_temp_info (   $info )

static

Decode the info field from backup_ids_temp or backup_files_temp.

Parameters

mixed

$info

The info field data to decode, may be an object or a simple integer.

Return values

mixed

The decoded information. For simple types it returns, for complex ones we decode.

encode_backup_temp_info()

static backup_controller_dbops::encode_backup_temp_info (   $info )

static

Encode the info field for backup_ids_temp or backup_files_temp.

Parameters

mixed

$info

string The info field data to encode.

Return values

string

An encoded string of data or null if the input is null.

get_moodle_backup_information()

static backup_controller_dbops::get_moodle_backup_information (   $backupid, core\progress\base  $progress = null  )

static

Get details information for main moodle_backup.xml file, extracting it from the specified controller.

If you specify the progress monitor, this will start a new progress section to track progress in processing (in case this task takes a long time).

Parameters

string	$backupid	Backup ID
core::progress::base	$progress	Optional progress monitor

get_progress()

static backup_controller_dbops::get_progress (   $backupid )

static

Get the progress details of a backup operation.

Get backup records directly from database, if the backup has successfully completed there will be no controller object to load.

Parameters

string

$backupid

The backup id to query.

Return values

array::$progress

The backup progress details.

save_controller()

static backup_controller_dbops::save_controller (   $controller,   $checksum,   $includeobj = true,   $cleanobj = false  )

static

Send one backup controller to DB.

Parameters

backup_controller	$controller	controller to send to DB
string	$checksum	hash of the controller to be checked
bool	$includeobj	to decide if the object itself must be updated (true) or no (false)
bool	$cleanobj	to decide if the object itself must be cleaned (true) or no (false)

Return values

int	id of the controller record in the DB
