Detailed Description

Abstract stage class.

This class should be extended by all backup stages (a requirement of many backup ui functions). Each stage must then define two abstract methods

• process : To process the stage
• initialise_stage_form : To get a backup_moodleform instance for the stage

__construct()

base_ui_stage::__construct	(	base_ui	$ui,
		array	$params = null
	)

Constructor.

Parameters

base_ui	$ui
array	$params

Reimplemented in restore_ui_stage_process.

Member Function Documentation

display()

base_ui_stage::display

(

core_backup_renderer

$renderer

)

Displays the stage.

By default this involves instantiating the form for the stage and the calling it to display.

Parameters

core_backup_renderer

$renderer

Return values

string

HTML code to echo

Reimplemented in backup_ui_stage_final, backup_ui_stage_complete, import_ui_stage_confirmation, restore_ui_stage_process, and restore_ui_stage_complete.

get_name()

base_ui_stage::get_name

(

)

The name of this stage.

Return values

string

Reimplemented in restore_ui_stage.

get_next_stage()

base_ui_stage::get_next_stage

(

)

The next stage.

Return values

int

Reimplemented in backup_ui_stage_initial, and import_ui_stage_precheck.

get_params()

base_ui_stage::get_params ( )

final

Returns the custom params for this stage.

Return values

array|null

get_prev_stage()

base_ui_stage::get_prev_stage ( )

final

The previous stage.

Return values

int

get_stage()

base_ui_stage::get_stage ( )

final

The current stage.

Return values

int

get_ui()

base_ui_stage::get_ui ( )

final

Returns the base UI class.

Return values

base_ui

get_uniqueid()

base_ui_stage::get_uniqueid ( )

final

The backup id from the backup controller.

Return values

string

initialise_stage_form()

base_ui_stage::initialise_stage_form ( )

abstractprotected

Creates an instance of the correct moodleform properly populated and all dependencies instantiated.

@abstract

Return values

backup_moodleform

Reimplemented in backup_ui_stage_initial, backup_ui_stage_schema, backup_ui_stage_confirmation, backup_ui_stage_final, import_ui_stage_precheck, import_ui_stage_confirmation, restore_ui_stage_settings, restore_ui_stage_schema, restore_ui_stage_review, and restore_ui_stage_process.

is_first_stage()

base_ui_stage::is_first_stage

(

)

Returns true if this stage is the first stage.

Return values

bool

Reimplemented in restore_ui_stage.

process()

base_ui_stage::process ( base_moodleform  $form = null )

abstract

Processes the stage.

This must be overridden by every stage as it will be different for every stage

@abstract

Parameters

base_moodleform

$form

Reimplemented in backup_ui_stage_schema, backup_ui_stage_confirmation, backup_ui_stage_final, import_ui_stage_precheck, restore_ui_stage_settings, restore_ui_stage_schema, restore_ui_stage_review, restore_ui_stage_process, and backup_ui_stage_initial.
