Class: backup_ui_stage - X-Ref
Abstract stage classThis 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(backup_ui $ui, array $params = null) X-Ref |
| Constructor. param: backup_ui $ui param: array $params |
| get_backupid() X-Ref |
| The backup id from the backup controller return: string |
Class: backup_ui_stage_initial - X-Ref
Class representing the initial stage of a backup.In this stage the user is required to set the root level settings.
| __construct(backup_ui $ui, array $params = null) X-Ref |
| Initial backup stage constructor param: backup_ui $ui param: array $params |
| process(base_moodleform $m = null) X-Ref |
| Processes the initial backup stage param: base_moodleform $m return: int The number of changes |
| get_next_stage() X-Ref |
| Gets the next stage for the backup. We override this function to implement the one click backup. When the user performs a one click backup we jump straight to the final stage. return: int |
| initialise_stage_form() X-Ref |
| Initialises the backup_moodleform instance for this stage return: backup_initial_form |
Class: backup_ui_stage_schema - X-Ref
Schema stage of backup processDuring the schema stage the user is required to set the settings that relate
to the area that they are backing up as well as its children.
| __construct(backup_ui $ui, array $params = null) X-Ref |
| Schema stage constructor param: backup_ui $ui param: array $params |
| process(base_moodleform $form = null) X-Ref |
| Processes the schema stage param: base_moodleform $form return: int The number of changes the user made |
| initialise_stage_form() X-Ref |
| Creates the backup_schema_form instance for this stage return: backup_schema_form |
Class: backup_ui_stage_confirmation - X-Ref
Confirmation stageOn this stage the user reviews the setting for the backup and can change the filename
of the file that will be generated.
| __construct($ui, array $params = null) X-Ref |
| Constructs the stage param: backup_ui $ui param: array $params |
| process(base_moodleform $form = null) X-Ref |
| Processes the confirmation stage param: base_moodleform $form return: int The number of changes the user made |
| initialise_stage_form() X-Ref |
| Creates the backup_confirmation_form instance this stage requires return: backup_confirmation_form |
Class: backup_ui_stage_final - X-Ref
Final stage of backupThis stage is special in that it is does not make use of a form. The reason for
this is the order of procession of backup at this stage.
The processesion is:
1. The final stage will be intialise.
2. The confirmation stage will be processed.
3. The backup will be executed
4. The complete stage will be loaded by execution
5. The complete stage will be displayed
This highlights that we neither need a form nor a display method for this stage
we simply need to process.
| __construct(backup_ui $ui, array $params = null) X-Ref |
| Constructs the final stage param: backup_ui $ui param: array $params |
| process(base_moodleform $form = null) X-Ref |
| Processes the final stage. In this case it ALWAYS passes processing to the previous stage (confirmation) param: base_moodleform $form return: bool |
| initialise_stage_form() X-Ref |
| should NEVER be called... throws an exception |
| display(core_backup_renderer $renderer) X-Ref |
| should NEVER be called... throws an exception param: core_backup_renderer $renderer return: void |
Class: backup_ui_stage_complete - X-Ref
The completed backup stageAt this stage everything is done and the user will be redirected to view the
backup file in the file browser.
| __construct(backup_ui $ui, array $params = null, array $results = null) X-Ref |
| Constructs the complete backup stage param: backup_ui $ui param: array $params param: array $results |
| display(core_backup_renderer $renderer) X-Ref |
| Displays the completed backup stage. Currently this just involves redirecting to the file browser with an appropriate message. param: core_backup_renderer $renderer return: string HTML code to echo |
