Member Function Documentation

add_plugin_structure()

restore_structure_step::add_plugin_structure ( $plugintype, $element )

protectedinherited

Add plugin structure to any element in the structure restore tree.

Parameters

string	$plugintype	type of plugin as defined by core_component\get_plugin_types()
restore_path_element	$element	element in the structure restore tree that we are going to add plugin information to

add_subplugin_structure()

restore_structure_step::add_subplugin_structure ( $subplugintype, $element, $plugintype = null, $pluginname = null )

protectedinherited

Add subplugin structure for a given plugin to any element in the structure restore tree.

This method allows the injection of subplugins (of a specific plugin) parsing and proccessing to any element in the restore structure.

NOTE: Initially subplugins were only available for activities (mod), so only the restore_activity_structure_step class had support for them, always looking for /mod/modulenanme subplugins. This new method is a generalization of the existing one for activities, supporting all subplugins injecting information everywhere.

Parameters

string	$subplugintype	type of subplugin as defined in plugin's db/subplugins.json.
restore_path_element	$element	element in the structure restore tree that we are going to add subplugin information to.
string	$plugintype	type of the plugin.
string	$pluginname	name of the plugin.

Return values

void

after_execute()

restore_structure_step::after_execute ( )

protectedinherited

This method will be executed after the whole structure step have been processed.

After execution method for code needed to be executed after the whole structure has been processed. Useful for cleaning tasks, files process and others. Simply overwrite in in your steps if needed

Reimplemented in restore_activity_grading_structure_step, restore_assign_activity_structure_step, restore_badges_structure_step, restore_bigbluebuttonbn_activity_structure_step, restore_book_activity_structure_step, restore_calendarevents_structure_step, restore_chat_activity_structure_step, restore_choice_activity_structure_step, restore_contentbankcontent_structure_step, restore_course_structure_step, restore_create_categories_and_questions, restore_data_activity_structure_step, restore_feedback_activity_structure_step, restore_folder_activity_structure_step, restore_forum_activity_structure_step, restore_glossary_activity_structure_step, restore_gradebook_structure_step, restore_groups_structure_step, restore_h5pactivity_activity_structure_step, restore_imscp_activity_structure_step, restore_label_activity_structure_step, restore_lesson_activity_structure_step, restore_lti_activity_structure_step, restore_outcomes_structure_step, restore_page_activity_structure_step, restore_resource_activity_structure_step, restore_scales_structure_step, restore_scorm_activity_structure_step, restore_section_structure_step, restore_survey_activity_structure_step, restore_url_activity_structure_step, restore_wiki_activity_structure_step, and restore_workshop_activity_structure_step.

after_restore()

restore_structure_step::after_restore ( )

protectedinherited

This method will be executed after the rest of the restore has been processed.

Use if you need to update IDs based on things which are restored after this step has completed.

Reimplemented in restore_activity_grades_structure_step, restore_forum_activity_structure_step, and restore_module_structure_step.

apply_date_offset()

restore_step::apply_date_offset ( $value )

inherited

Apply course startdate offset based in original course startdate and course_offset_startdate setting Note we are using one static cache here, but by restoreid, so it's ok for concurrence/multiple executions in the same request.

Note: The policy is to roll date only for configurations and not for user data. see MDL-9367.

Parameters

int

$value

Time value (seconds since epoch), or empty for nothing

Return values

int	Time value after applying the date offset, or empty for nothing

decrypt()

restore_step::decrypt ( $value )

inherited

Returns symmetric-key AES-256 decryption of base64 encoded contents.

This method is used in restore operations to decrypt contents encrypted with encrypted_final_element automatically decoding (base64) and decrypting contents using the key stored in backup_encryptkey config.

Requires openssl, cipher availability, and key existence (backup automatically sets it if missing). Integrity is provided via HMAC.

Parameters

string

$value

encrypted_final_element value to decode and decrypt.

Return values

string|null

decoded and decrypted value or null if the operation can not be performed.

define_structure()

restore_comments_structure_step::define_structure ( )

protected

Function that will return the structure to be processed by this restore_step.

Must return one array of @restore_path_element elements

Reimplemented from restore_structure_step.

destroy()

base_step::destroy ( )

inherited

Destroy all circular references.

It helps PHP 5.2 a lot!

execute()

restore_structure_step::execute ( )

finalinherited

This function will perform all the actions necessary to achieve the execution of the plan/part/task.

Implements executable.

execute_condition()

restore_structure_step::execute_condition ( )

protectedinherited

To conditionally decide if one step will be executed or no.

For steps needing to be executed conditionally, based in dynamic conditions (at execution time vs at declaration time) you must override this function. It will return true if the step must be executed and false if not

Reimplemented in restore_activity_competencies_structure_step, restore_activity_grade_history_structure_step, restore_activity_grades_structure_step, restore_activity_grading_structure_step, restore_badges_structure_step, restore_course_competencies_structure_step, restore_course_completion_structure_step, restore_course_loglastaccess_structure_step, restore_course_logs_structure_step, restore_course_logstores_structure_step, restore_enrolments_structure_step, restore_grade_history_structure_step, restore_gradebook_structure_step, and restore_userscompletion_structure_step.

get_mappingid()

restore_structure_step::get_mappingid ( $itemname, $oldid, $ifnotfound = false )

inherited

Return the new id of a mapping for the given itemname.

Parameters

string	$itemname	the type of item
int	$oldid	the item ID from the backup
mixed	$ifnotfound	what to return if $oldid wasnt found. Defaults to false

get_task()

restore_structure_step::get_task ( )

inherited

As far as restore structure steps are implementing restore_plugin stuff, they need to have the parent task available for wrapping purposes (get course/context....)

Return values

restore_task|null

grouped_parent_exists()

restore_structure_step::grouped_parent_exists ( $pelement, $elements )

inherited

Given one pathelement, return true if grouped parent was found.

Parameters

restore_path_element	$pelement	the element we are interested in.
restore_path_element[]	$elements	the elements that exist.

Return values

bool	true if this element is inside a grouped parent.

launch_after_execute_methods()

restore_structure_step::launch_after_execute_methods ( )

protectedinherited

Launch all the after_execute methods present in all the processing objects.

This method will launch all the after_execute methods that can be defined both in restore_plugin and restore_structure_step classes

For restore_plugin classes the name of the method to be executed will be "after_execute_" + connection point (as far as can be multiple connection points in the same class)

For restore_structure_step classes is will be, simply, "after_execute". Note that this is executed after the plugin ones

launch_after_restore_methods()

restore_structure_step::launch_after_restore_methods ( )

inherited

Launch all the after_restore methods present in all the processing objects.

This method will launch all the after_restore methods that can be defined both in restore_plugin class

For restore_plugin classes the name of the method to be executed will be "after_restore_" + connection point (as far as can be multiple connection points in the same class)

log()

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

inherited

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.

Implements loggable.

set_mapping()

restore_structure_step::set_mapping ( $itemname, $oldid, $newid, $restorefiles = false, $filesctxid = null, $parentid = null )

inherited

To send ids pairs to backup_ids_table and to store them into paths.

This method will send the given itemname and old/new ids to the backup_ids_temp table, and, at the same time, will save the new id into the corresponding restore_path_element for easier access by children. Also will inject the known old context id for the task in case it's going to be used for restoring files later
