Class: restore_ui  - X-Ref

This is the restore user interface class

The restore user interface class manages the user interface and restore for
Moodle.

initialise_stage($stage = null, array $params = null)   X-Ref
Intialises what ever stage is requested. If none are requested we check
params for 'stage' and default to initial

param: int|null $stage The desired stage to intialise or null for the default
param: array $params
return: restore_ui_stage_initial|restore_ui_stage_schema|restore_ui_stage_confirmation|restore_ui_stage_final

process()   X-Ref
This processes the current stage of the restore

return: bool

is_independent()   X-Ref

return: string

get_restoreid()   X-Ref
Gets the restore id from the controller

return: string

get_progress_reporter()   X-Ref
Gets the progress reporter object in use for this restore UI.

IMPORTANT: This progress reporter is used only for UI progress that is
outside the restore controller. The restore controller has its own
progress reporter which is used for progress during the main restore.
Use the restore controller's progress reporter to report progress during
a restore operation, not this one.

This extra reporter is necessary because on some restore UI screens,
there are long-running tasks even though there is no restore controller
in use.

return: \core\progress\none

Sets the progress reporter that will be returned by get_progress_reporter.

engage_independent_stage($stage, $contextid)   X-Ref
