SubscribableJob

SubscribableJob

This is a type of Job object that allows you to subscribe to updates to the Job. It is returned by the JobQueue's add() method. Note that the subscription capability is only supported if the JobQueueStrategy implements the InspectableJobQueueStrategy interface (e.g. the SqlJobQueueStrategy does support this).
