Detailed Description

Parent class for all backup settings.

Constructor & Destructor Documentation

◆ __construct()

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

{Instantiates a setting object.

Parameters
string$nameName of the setting
string$vtypeType of the setting, eg self::IS_TEXT
mixed$valueValue of the setting
bool$visibilityIs the setting visible in the UI, eg self::VISIBLE
int$statusStatus of the setting with regards to the locking, eg self::NOT_LOCKED
}

Reimplemented from base_setting.

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

Member Function Documentation

◆ add_dependency()

backup_setting::add_dependency ( base_setting $dependentsetting,
$type = setting_dependency::DISABLED_VALUE,
$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$dependentsetting
int$typeOne of setting_dependency::*
array$options

Reimplemented from base_setting.

◆ calculate_checksum()

backup_setting::calculate_checksum ( )

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

Implements checksumable.

◆ destroy()

base_setting::destroy ( )
inherited

Destroy all circular references.

It helps PHP 5.2 a lot!

◆ get_help()

base_setting::get_help ( )
inherited

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

Return values
array|falseAn array (identifier, component) or false if not set

◆ get_level()

backup_setting::get_level ( )
Return values
intLevel of the setting, eg self::ROOT_LEVEL

◆ get_my_dependency_properties()

base_setting::get_my_dependency_properties ( $settingname = null)
inherited

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 ( )
inherited

Get the PARAM_XXXX validation to be applied to the setting.

Return values
stringThe PARAM_XXXX constant of null if the setting type is not defined

◆ get_settings_depended_on()

base_setting::get_settings_depended_on ( )
inherited

Returns all of the dependencies that affect this setting.

e.g. settings this setting depends on.

Return values
arrayArray of setting_dependency's

◆ get_ui()

base_setting::get_ui ( )
inherited

Gets the user interface for this setting.

Return values
base_setting_ui

◆ has_dependencies_on_settings()

base_setting::has_dependencies_on_settings ( )
inherited

Checks if this setting is dependent on any other settings.

Return values
boolTrue if this setting is dependent on any other settings

◆ has_dependent_settings()

base_setting::has_dependent_settings ( )
inherited

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

Return values
boolTrue if there are other settings that are dependent on this setting

◆ has_help()

base_setting::has_help ( )
inherited

Returns true if help has been set for this setting.

Return values
cool

◆ is_checksum_correct()

backup_setting::is_checksum_correct ( $checksum)

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

Implements checksumable.

◆ make_ui()

backup_setting::make_ui ( $type,
$label,
array $attributes = null,
array $options = null )

Creates and sets a user interface for this setting given appropriate arguments.

Parameters
int$type
string$label
array$attributes
array$options

◆ register_dependency()

base_setting::register_dependency ( setting_dependency $dependency)
inherited

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)
protectedinherited

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' )
inherited

Sets a help string for this setting.

Parameters
string$identifier
string$component

◆ set_ui()

base_setting::set_ui ( backup_setting_ui $ui)
inherited

Sets the user interface for this setting.

Parameters
base_setting_ui$ui

◆ validate_value()

base_setting::validate_value ( $vtype,
$value )
protectedinherited
