execute()

quiz_statistics\task\recalculate::execute

(

)

Do the job.

Throw exceptions on errors (the job will be retried).

Reimplemented from core\task\task_base.

get_component()

core\task\task_base::get_component ( )

inherited

Getter for $component.

Return values

string

get_concurrency_limit()

core\task\adhoc_task::get_concurrency_limit ( )

finalinherited

Returns effective concurrency limit for this task.

Return values

int	effective concurrency limit for this task

get_cron_lock()

core\task\task_base::get_cron_lock ( )

inherited

Get the current lock for the entire cron.

Return values

core\lock\lock

get_custom_data()

core\task\adhoc_task::get_custom_data ( )

inherited

Getter for $customdata.

Return values

mixed

(anything that can be handled by json_decode).

get_custom_data_as_string()

core\task\adhoc_task::get_custom_data_as_string ( )

inherited

Alternate getter for $customdata.

Return values

string

this is the raw json encoded version.

get_default_concurrency_limit()

core\task\adhoc_task::get_default_concurrency_limit ( )

protectedinherited

Returns default concurrency limit for this task.

Return values

int	default concurrency limit

get_fail_delay()

core\task\task_base::get_fail_delay ( )

inherited

inherited

Getter for $hostname.

Return values

string

get_id()

core\task\adhoc_task::get_id ( )

inherited

Getter for $id.

Return values

int|null\$id

get_lock()

core\task\task_base::get_lock ( )

inherited

Get the current lock for this task.

Return values

core\lock\lock

get_name()

quiz_statistics\task\recalculate::get_name

(

)

Provide default implementation of the task name for backward compatibility.

Extending classes are expected to implement this method to provide a descriptive name for the task (shown to admins)

Return values

string

Reimplemented from core\task\adhoc_task.

get_next_run_time()

core\task\task_base::get_next_run_time ( )

inherited

Get the next run time for this task.

Return values

int

timestamp

get_pid()

core\task\task_base::get_pid ( )

inherited

Getter for $pid.

Return values

int

get_runtime()

core\task\task_base::get_runtime ( )

inherited

Returns task runtime.

Return values

int

get_runtime_result()

core\task\task_base::get_runtime_result ( )

inherited

Returns if the task has been running for too long.

Return values

result

get_timestarted()

core\task\task_base::get_timestarted ( )

inherited

Getter for $timestarted.

Return values

int

get_userid()

core\task\adhoc_task::get_userid ( )

inherited

Getter for $userid.

Return values

int|null\$userid

instance()

static quiz_statistics\task\recalculate::instance ( int $quizid )

static

Create a new instance of the task.

This sets the properties so that only one task will be queued at a time for a given quiz.

Parameters

int

$quizid

Return values

recalculate

is_blocking()

core\task\task_base::is_blocking ( )

inherited

Getter for $blocking.

Return values

bool

Return values

bool	true when enabled. false otherwise.

queue_future_run()

static quiz_statistics\task\recalculate::queue_future_run ( int $quizid )

static

Queue an instance of this task to happen after a delay.

Multiple events may happen over a short period that require a recalculation. Rather than run the recalculation each time, this will queue a single run of the task for a given quiz, within the delay period.

Parameters

int

$quizid

The quiz to run the recalculation for.

Return values

bool	true of the task was queued.

set_blocking()
