Class: grade_object - X-Ref
An abstract object that holds methods and attributes common to all grade_* objects defined here.| __construct($params=NULL, $fetch=true) X-Ref |
| Constructor. Optionally (and by default) attempts to fetch corresponding row from the database param: array $params An array with required parameters for this grade object. param: bool $fetch Whether to fetch corresponding row from the database or not, |
| load_optional_fields() X-Ref |
| Makes sure all the optional fields are loaded. If id present, meaning the instance exists in the database, then data will be fetched from the database. Defaults are used for new instances. |
| fetch($params) X-Ref |
| Finds and returns a grade_object instance based on params. param: array $params associative arrays varname=>value return: object grade_object instance or false if none found. |
| fetch_all($params) X-Ref |
| Finds and returns all grade_object instances based on $params. param: array $params Associative arrays varname=>value return: array|bool Array of grade_object instances or false if none found. |
| fetch_helper($table, $classname, $params) X-Ref |
| Factory method which uses the parameters to retrieve matching instances from the database param: string $table The table to retrieve from param: string $classname The name of the class to instantiate param: array $params An array of conditions like $fieldname => $fieldvalue return: mixed An object instance or false if not found |
| fetch_all_helper($table, $classname, $params) X-Ref |
| Factory method which uses the parameters to retrieve all matching instances from the database param: string $table The table to retrieve from param: string $classname The name of the class to instantiate param: array $params An array of conditions like $fieldname => $fieldvalue return: array|bool Array of object instances or false if not found |
| update($source = null, $isbulkupdate = false) X-Ref |
| Updates this object in the Database, based on its object variables. ID must be set. param: string $source from where was the object updated (mod/forum, manual, etc.) param: bool $isbulkupdate If bulk grade update is happening. return: bool success |
| delete($source=null) X-Ref |
| Deletes this object from the database. param: string $source From where was the object deleted (mod/forum, manual, etc.) return: bool success |
| get_record_data() X-Ref |
| Returns object with fields and values that are defined in database return: stdClass |
| insert($source = null, $isbulkupdate = false) X-Ref |
| Records this object in the Database, sets its id to the returned value, and returns that value. If successful this function also fetches the new object data from database and stores it in object properties. param: string $source From where was the object inserted (mod/forum, manual, etc.) param: string $isbulkupdate If bulk grade update is happening. return: int The new grade object ID if successful, false otherwise |
| update_from_db() X-Ref |
| Using this object's id field, fetches the matching record in the DB, and looks at each variable in turn. If the DB has different data, the db's data is used to update the object. This is different from the update() function, which acts on the DB record based on the object. return: bool True if successful |
| set_properties(&$instance, $params) X-Ref |
| Given an associated array or object, cycles through each key/variable and assigns the value to the corresponding variable in this object. param: grade_object $instance The object to set the properties on param: array $params An array of properties to set like $propertyname => $propertyvalue return: array|stdClass Either an associative array or an object containing property name, property value pairs |
| notify_changed($deleted) X-Ref |
| Called immediately after the object data has been inserted, updated, or deleted in the database. Default does nothing, can be overridden to hook in special behaviour. param: bool $deleted |
| add_feedback_files(int $historyid = null) X-Ref |
| Handles adding feedback files in the gradebook. param: int|null $historyid |
| update_feedback_files(int $historyid = null) X-Ref |
| Handles updating feedback files in the gradebook. param: int|null $historyid |
| delete_feedback_files() X-Ref |
| Handles deleting feedback files in the gradebook. |
| is_hidden() X-Ref |
| Returns the current hidden state of this grade_item This depends on the grade object hidden setting and the current time if hidden is set to a "hidden until" timestamp return: bool Current hidden state |
| is_hiddenuntil() X-Ref |
| Check grade object hidden status return: bool True if a "hidden until" timestamp is set, false if grade object is set to always visible or always hidden. |
| get_hidden() X-Ref |
| Check a grade item hidden status. return: int 0 means visible, 1 hidden always, a timestamp means "hidden until" |
| set_hidden($hidden, $cascade=false) X-Ref |
| Set a grade object hidden status param: int $hidden 0 means visiable, 1 means hidden always, a timestamp means "hidden until" param: bool $cascade Ignored |
| can_control_visibility() X-Ref |
| Returns whether the grade object can control the visibility of the grades. return: bool |
