Concrete implementations of a task must extend this and implement run();
Applications can use $this->log() for logging.

Methods
__construct()
Constructor hooks this task into the cron job action.
public
__construct() : mixed
Call this after your sub-class constructor.
This way, any changes you make to $this->priority will have an effect.
WARNING: If you forget to call parent::__construct();, your task will not run.
Return values
mixed —log()
Cron task logging.
public
final log(string $message[, bool $force = false ]) : void
Migration task is always logged.
Parameters
- $message : string
-
The string to log.
- $force : bool = false
-
Whether to force log the string, even if no verbose logging is checked.
Return values
void —register()
public
final static register() : void
Return values
void —run()
Do the task.
public
run() : void
Concrete implementations must do the work here in chuncks. The max execution time, usually about 15 or 30 secs must be eenough for all the tasks. So be careful!
