Detailed Description

Job that has a run() method and metadata accessors for JobQueue::pop() and JobQueue::ack()

Instances are not only enqueueable via JobQueue::push(), but they can also be executed by by calling their run() method. When constructing a job to be enqueued via JobQueue::push(), it will not be possible to construct a RunnableJob instance if the class for that job is not loaded by the application for the local DB domain. In that case, the general-purpose JobSpecification class can be used instead.
