Public Member Functions
	destroy ()
	Destroy all circular references.
	execute ()
	This function will perform all the actions necessary to achieve the execution of the plan/part/task.
	get_name ()
	get_task ()
	As far as backup structure steps are implementing backup_plugin stuff, they need to have the parent task available for wrapping purposes (get course/context....)
	log ($message, $level, $a=null, $depth=null, $display=false)
	This function will be responsible for handling the params, and to call to the corresponding logger->process() once all modifications in params have been performed.
	set_task ($task)

Protected Member Functions
	add_plugin_structure ($plugintype, $element, $multiple)
	Add plugin structure to any element in the structure backup tree.

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

	Wraps any activity backup structure within the common 'activity' element that will include common to all activities information like id, context...
	setting_exists ($name)

Protected Attributes
backup_xml_transformer null	$contenttransformer
	xml content transformer being used (need it here, apart from xml_writer, thanks to serialized data to process - say thanks to blocks!)
string	$filename
	Name of the file to be generated.
string	$name
	One simple name for identification purposes.
base_task null	$task
	Task this is part of.

Detailed Description

Define all the backup steps that will be used by the backup_survey_activity_task.

Define the complete survey structure for backup, with file and id annotations

Member Function Documentation

add_plugin_structure()

backup_structure_step::add_plugin_structure ( $plugintype, $element, $multiple )

protectedinherited

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

Parameters

string	$plugintype	type of plugin as defined by core_component\get_plugin_types()
backup_nested_element	$element	element in the structure backup tree that we are going to add plugin information to
bool	$multiple	to define if multiple plugins can produce information for each instance of $element (true) or no (false)

add_subplugin_structure()

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

protectedinherited

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

This method allows the injection of subplugins (of a specified plugin) data to any element in any backup structure.

NOTE: Initially subplugins were only available for activities (mod), so only the backup_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.
backup_nested_element	$element	element in the backup tree (anywhere) that we are going to add subplugin information to.
bool	$multiple	to define if multiple subplugins can produce information for each instance of $element (true) or no (false).
string	$plugintype	type of the plugin.
string	$pluginname	name of the plugin.

Return values

void

define_structure()

backup_survey_activity_structure_step::define_structure ( )

protected

Define the structure to be processed by this backup step.

Return values

backup_nested_element

Reimplemented from backup_structure_step.

destroy()

base_step::destroy ( )

inherited

Destroy all circular references.

It helps PHP 5.2 a lot!

execute()

backup_structure_step::execute ( )

inherited

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

Implements executable.

execute_condition()

backup_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

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.

prepare_activity_structure()

backup_activity_structure_step::prepare_activity_structure ( $activitystructure )

protectedinherited

Wraps any activity backup structure within the common 'activity' element that will include common to all activities information like id, context...

Parameters

backup_nested_element

$activitystructure

the element to wrap

Return values

backup_nested_element

the $activitystructure wrapped by the common 'activity' element
