Member Function Documentation

◆ add_logger()

base_controller::add_logger ( base_logger $logger)

Inserts a new logger at end of logging chain.

Parameters
base_logger$loggerNew logger to add

◆ calculate_checksum()

checksumable::calculate_checksum ( )
inherited

This function will return one unique and stable checksum for one instance of the class implementing it.

It's each implementation responsibility to do it recursively if needed and use optional store (caching) of the checksum if necessary/possible

Implemented in backup_controller, backup_setting, base_logger, base_plan, base_task, and restore_controller.

◆ get_copy()

base_controller::get_copy ( )

Get the course copy data.

Return values
stdClass
Deprecated
since Moodle 4.1 MDL-74548 - please do not use this method anymore.
Todo
MDL-75026 This method will be deleted in Moodle 4.5
See also
restore_controller\get_copy()

Reimplemented in restore_controller.

◆ get_logger()

base_controller::get_logger ( )

Gets first logger in logging chain.

Return values
base_loggerLogger

◆ get_progress()

base_controller::get_progress ( )

Gets the progress reporter, which can be used to report progress within the backup or restore process.

Return values
core\progress\baseProgress reporting object

◆ get_releasesession()

base_controller::get_releasesession ( )

Returns the set value of releasesession.

This is used to indicate if the session should be closed during the backup/restore.

Return values
boolIndicates whether the session should be released.

◆ is_checksum_correct()

checksumable::is_checksum_correct ( $checksum)
inherited

Given one checksum, returns if matches object's checksum (true) or no (false)

Implemented in backup_controller, backup_setting, base_logger, base_plan, base_task, and restore_controller.

◆ log()

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

Logs data to the logger chain.

See also
loggable\log()

Implements loggable.

◆ set_copy()

base_controller::set_copy ( \stdClass $data)

Store extra data for course copy operations.

For a course copying these is data required to be passed to the restore step. We store this data in its own section of the backup controller

Parameters
stdClass$dataThe course copy data.
Exceptions
backup_controller_exception
Deprecated
since Moodle 4.1 MDL-74548 - please do not use this method anymore.
Todo
MDL-75025 This method will be deleted in Moodle 4.5
See also
restore_controller\__construct()

◆ set_progress()

base_controller::set_progress ( \core\progress\base $progress)

Sets the progress reporter.

Parameters
core\progress\base$progressProgress reporting object

Member Data Documentation

◆ CIPHERKEYLEN

const backup::CIPHERKEYLEN = 32
inherited

Bytes enforced for key, using the cypher above.

Restrictive? Yes, but better than unsafe lengths

◆ MODE_ASYNC

const backup::MODE_ASYNC = 70
inherited

This mode is for asynchronous backups.

These backups will run via adhoc scheduled tasks.

◆ MODE_COPY

const backup::MODE_COPY = 80
inherited

This mode is for course copies.

It is similar to async, but identifies back up and restore tasks as course copies.

These copies will run via adhoc scheduled tasks.

◆ MODE_IMPORT

const backup::MODE_IMPORT = 20
inherited

This is used for importing courses, and for duplicating activities.

This mode will ensure that files are not included in the backup generation, and during a restore they are copied from the existing file record.

◆ MODE_SAMESITE

const backup::MODE_SAMESITE = 40
inherited

This mode is intended for duplicating courses and cases where the backup target is within the same site.

This mode will ensure that files are not included in the backup generation, and during a restore they are copied from the existing file record.

For creating a backup for archival purposes or greater longevity, use MODE_GENERAL.
