QueueWorkerInterface::processItem

public QueueWorkerInterface::processItem($data)

Works on a single queue item.

Parameters

mixed $data: The data that was passed to \Drupal\Core\Queue\QueueInterface::createItem() when the item was queued.

Throws

\Drupal\Core\Queue\RequeueException Processing is not yet finished. This will allow another process to claim the item immediately.

\Exception A QueueWorker plugin may throw an exception to indicate there was a problem. The cron process will log the exception, and leave the item in the queue to be processed again later.

\Drupal\Core\Queue\SuspendQueueException More specifically, a SuspendQueueException should be thrown when a QueueWorker plugin is aware that the problem will affect all subsequent workers of its queue. For example, a callback that makes HTTP requests may find that the remote server is not responding. The cron process will behave as with a normal Exception, and in addition will not attempt to process further items from the current item's queue during the current cron run.
