| process_actions($quiz, $cm, $currentgroup, \core\dml\sql_join $groupstudentsjoins,\core\dml\sql_join $allowedjoins, $redirecturl) X-Ref |
| Extends parent function processing any submitted actions. param: object $quiz param: object $cm param: int $currentgroup param: \core\dml\sql_join $groupstudentsjoins (joins, wheres, params) param: \core\dml\sql_join $allowedjoins (joins, wheres, params) param: moodle_url $redirecturl |
| start_regrade($quiz, $cm) X-Ref |
| Check necessary capabilities, and start the display of the regrade progress page. param: object $quiz the quiz settings. param: object $cm the cm object for the quiz. |
| finish_regrade($nexturl) X-Ref |

| unlock_session() X-Ref |
| Unlock the session and allow the regrading process to run in the background. |
| regrade_attempt($attempt, $dryrun = false, $slots = null) X-Ref |
| Regrade a particular quiz attempt. Either for real ($dryrun = false), or as a pretend regrade to see which fractions would change. The outcome is stored in the quiz_overview_regrades table. Note, $attempt is not upgraded in the database. The caller needs to do that. However, $attempt->sumgrades is updated, if this is not a dry run. param: object $attempt the quiz attempt to regrade. param: bool $dryrun if true, do a pretend regrade, otherwise do it for real. param: array $slots if null, regrade all questions, otherwise, just regrade return: array messages array with keys slot number, and values reasons why that slot cannot be regraded. |

| For use in tests only. Clear the cached regrade data. |
| get_new_question_for_regrade(stdClass $attempt,question_usage_by_activity $quba, int $slot) X-Ref |
| Work out of we should be using a new question version for a particular slot in a regrade. param: stdClass $attempt the attempt being regraded. param: question_usage_by_activity $quba the question_usage corresponding to that. param: int $slot which slot is currently being regraded. return: question_definition other question version to use for this slot. |
| regrade_attempts($quiz, $dryrun = false,\core\dml\sql_join$groupstudentsjoins = null, $attemptids = array() X-Ref |
| Regrade attempts for this quiz, exactly which attempts are regraded is controlled by the parameters. param: object $quiz the quiz settings. param: bool $dryrun if true, do a pretend regrade, otherwise do it for real. param: \core\dml\sql_join|array $groupstudentsjoins empty for all attempts, otherwise regrade attempts param: array $attemptids blank for all attempts, otherwise only regrade |
| regrade_attempts_needing_it($quiz, \core\dml\sql_join $groupstudentsjoins) X-Ref |
| Regrade those questions in those attempts that are marked as needing regrading in the quiz_overview_regrades table. param: object $quiz the quiz settings. param: \core\dml\sql_join $groupstudentsjoins empty for all attempts, otherwise regrade attempts |
| regrade_batch_of_attempts($quiz, array $attempts,bool $dryrun, \core\dml\sql_join $groupstudentsjoins) X-Ref |
| This is a helper used by {@link regrade_attempts()} and {@link regrade_attempts_needing_it()}. Given an array of attempts, it regrades them all, or does a dry run. Each object in the attempts array must be a row from the quiz_attempts table, with the \core_user\fields::for_name() fields from the user table joined in. In addition, if $attempt->regradeonlyslots is set, then only those slots are regraded, otherwise all slots are regraded. param: object $quiz the quiz settings. param: array $attempts of data from the quiz_attempts table, with extra data as above. param: bool $dryrun if true, do a pretend regrade, otherwise do it for real. param: \core\dml\sql_join $groupstudentsjoins empty for all attempts, otherwise regrade attempts |
| count_question_attempts_needing_regrade($quiz, \core\dml\sql_join $groupstudentsjoins) X-Ref |
| Count the number of attempts in need of a regrade. param: object $quiz the quiz settings. param: \core\dml\sql_join $groupstudentsjoins (joins, wheres, params) If this is given, only data relating return: int the number of attempts. |

| Are there any pending regrades in the table we are going to show? param: string $from tables used by the main query. param: string $where where clause used by the main query. param: array $params required by the SQL. return: bool whether there are pending regrades. |
| clear_regrade_table($quiz, \core\dml\sql_join $groupstudentsjoins) X-Ref |
