Class represents a grading form definition used in a particular area.
General data about definition is stored in the standard DB table grading_definitions. A separate entry is created for each grading area (i.e. for each module). Plugins may define and use additional tables to store additional data about definitions.
Advanced grading plugins must declare a class gradingform_xxxx_controller extending this class and put it in lib.php in the plugin folder.
See gradingform_rubric_controller as an example
Except for overwriting abstract functions, plugin developers may want to overwrite functions responsible for loading and saving of the definition to include additional data stored.

Overridden by sub classes that wish to make definition details available to web services.
When not overridden, only definition data common to all grading methods is made available. When overriding, the return value should be an array containing one or more key/value pairs. These key/value pairs should match the definition returned by the get_definition() function. For examples, look at: $gradingform_rubric_controller->get_external_definition_details() $gradingform_guide_controller->get_external_definition_details()
| array | An array of one or more key/value pairs containing the external_multiple_structure/s corresponding to the definition returned by $controller->get_definition() |
Reimplemented in gradingform_guide_controller, and gradingform_rubric_controller.

Overridden by sub classes that wish to make instance filling details available to web services.
When not overridden, only instance filling data common to all grading methods is made available. When overriding, the return value should be an array containing one or more key/value pairs. These key/value pairs should match the filling data returned by the get_<method>_filling() function in the gradingform_instance subclass. For examples, look at: $gradingform_rubric_controller->get_external_instance_filling_details() $gradingform_guide_controller->get_external_instance_filling_details()
| array | An array of one or more key/value pairs containing the external_multiple_structure/s corresponding to the definition returned by $gradingform_<method>instance->get<method>_filling() |

| boolean |
| gradingform_controller::is_form_available | ( | ) |
Is the grading form defined and ready for usage?
| boolean |
| gradingform_controller::is_form_defined | ( | ) |
Is the form definition record available?

| boolean |
| gradingform_controller::is_own_form | ( | $userid = null | ) |
Is the grading form owned by the given user?
The form owner is the user who created this instance of the form.
| int | $userid | the user id to check, defaults to the current user |
| boolean|null | null if the form not defined yet, boolean otherwise |
| gradingform_controller::is_shared_template | ( | ) |

The default implementation just tries to load the record from the {grading_definitions} table. The plugins are likely to override this with a more complex query that loads all required data at once.

| gradingform_controller::render_grade | ( | $page, | |
| $itemid, | |||

Plugins are forced to override this. Ideally they should delegate the task to their own renderer.
| moodle_page | $page | the target page |
| string |
Reimplemented in gradingform_guide_controller, and gradingform_rubric_controller.
|
final |
Sets the range of grades used in this area.
This is usually either range like 0-100 or the scale where keys start from 1.
Typically modules will call it: $controller->set_grade_range(make_grades_menu($gradingtype), $gradingtype > 0); Negative $gradingtype means that scale is used and the grade must be rounded to the nearest int. Positive $gradingtype means that range 0..$gradingtype is used for the grades and in this case grade does not have to be rounded.
Sometimes modules always expect grade to be rounded (like mod_assign does).
| array | $graderange | array where first key is the minimum grade and the last key is the maximum grade. |
| bool | $allowgradedecimals | if decimal values are allowed as grades. |
|
static |
Prepare the part of the search query to append to the FROM statement.

Prepare the parts of the SQL WHERE statement to search for the given token.
The returned array cosists of the list of SQL comparions and the list of respective parameters for the comparisons. The returned chunks will be joined with other conditions using the OR operator.
| string | $token | token to search for |
| array |
Reimplemented in gradingform_guide_controller, and gradingform_rubric_controller.
| gradingform_controller::update_definition | ( | stdClass | $definition, |
| $usermodified = null ) |
Saves the defintion data into the database.
The implementation in this base class stores the common data into the record into the {grading_definition} table. The plugins are likely to extend this and save their data into own tables, too.
| stdClass | $definition | data containing values for the {grading_definition} table |
| int | null | $usermodified | optional userid of the author of the definition, defaults to the current user |
