Detailed Description

This abstract class defines one basic setting.

Each setting will be able to control its name, value (from a list), ui representation (check box, drop down, text field...), visibility, status (editable/locked...) and its hierarchy with other settings (using one like-observer pattern.

Constructor & Destructor Documentation

◆ __construct()

base_setting::__construct	(	$name,
		$vtype,
		$value = `null`,
		$visibility = `self::VISIBLE`,
		$status = `self::NOT_LOCKED`
	)

Instantiates a setting object.

Parameters

string	$name	Name of the setting
string	$vtype	Type of the setting, eg self::IS_TEXT
mixed	$value	Value of the setting
bool	$visibility	Is the setting visible in the UI, eg self::VISIBLE
int	$status	Status of the setting with regards to the locking, eg self::NOT_LOCKED

Reimplemented in backup_filename_setting, restore_course_generic_text_setting, activity_backup_setting, backup_setting, course_backup_setting, root_backup_setting, and section_backup_setting.

Member Function Documentation

◆ add_dependency()

base_setting::add_dependency	(	base_setting	$dependentsetting,
			$type = `null`,
			$options = `array()`
	)

Quick method to add a dependency to this setting.

The dependency created is done so by inspecting this setting and the setting that is passed in as the dependent setting.

Parameters

base_setting	$dependentsetting
int	$type	One of setting_dependency::*
array	$options

Reimplemented in backup_setting.

◆ destroy()

base_setting::destroy ( )

Destroy all circular references.

It helps PHP 5.2 a lot!

◆ get_help()

base_setting::get_help ( )

Gets the help string params for this setting if it has been set.

Return values

array|false An array (identifier, component) or false if not set

◆ get_my_dependency_properties()

base_setting::get_my_dependency_properties ( $settingname = null )

Gets an array of properties for all of the dependencies that will affect this setting.

This method returns an array rather than the dependencies in order to minimise the memory footprint of for the potentially huge recursive dependency structure that we may be dealing with.

This method also ensures that all dependencies are transmuted to affect the setting in question and that we don't provide any duplicates.

Parameters

string | null $settingname

Return values

array

◆ get_param_validation()

base_setting::get_param_validation ( )

Get the PARAM_XXXX validation to be applied to the setting.

Return values

string The PARAM_XXXX constant of null if the setting type is not defined

◆ get_settings_depended_on()

base_setting::get_settings_depended_on ( )

Returns all of the dependencies that affect this setting.

e.g. settings this setting depends on.

Return values

array Array of setting_dependency's

◆ get_ui()

base_setting::get_ui ( )

Gets the user interface for this setting.

Return values

base_setting_ui

◆ has_dependencies_on_settings()

base_setting::has_dependencies_on_settings ( )

Checks if this setting is dependent on any other settings.

Return values

bool	True if this setting is dependent on any other settings

◆ has_dependent_settings()

base_setting::has_dependent_settings ( )

Checks if there are other settings that are dependent on this setting.

Return values

bool	True if there are other settings that are dependent on this setting

◆ has_help()

base_setting::has_help ( )

Returns true if help has been set for this setting.

Return values

cool

◆ register_dependency()

base_setting::register_dependency ( setting_dependency $dependency )

Adds a dependency where another setting depends on this setting.

Parameters

setting_dependency $dependency

◆ register_dependent_dependency()

base_setting::register_dependent_dependency ( setting_dependency $dependency )

protected

Adds a dependency where this setting is dependent on another.

This should only be called internally once we are sure it is not cicrular.

Parameters

setting_dependency $dependency

◆ set_help()

base_setting::set_help	(	$identifier,
		$component = `'moodle'`
	)

Sets a help string for this setting.

Parameters

string	$identifier
string	$component

◆ set_ui()

base_setting::set_ui ( backup_setting_ui $ui )

Sets the user interface for this setting.

Parameters

base_setting_ui $ui

◆ validate_value()

base_setting::validate_value	(	$vtype,
		$value
	)

protected

Reimplemented in restore_course_defaultcustom_setting.
