Detailed Description

generic activity setting to pass various settings between tasks and steps

Member Function Documentation

add_dependency()

backup_setting::add_dependency ( base_setting $dependentsetting, $type = setting_dependency::DISABLED_VALUE, $options = array() )

inherited

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 from base_setting.

calculate_checksum()

backup_setting::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

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|false

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

get_level()

backup_setting::get_level ( )

inherited

Return values

int	Level 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

string

The 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

array

Array 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

bool	True 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

bool	True 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 )

inherited

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 )

inherited

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

Reimplemented in restore_course_defaultcustom_setting.
