This module is now deprecated in favor of Proc::JobQueue::EventQueue.
This module is a sublcass of Proc::JobQueue. It combines a job queue with a a dependency graph, Object::Dependency.
The jobs that it runs are either full-fledged jobs, Proc::JobQueue::DependencyJob, or simple synchronous one-shot perl callbacks that execute as soon as their prerequisites are met: Proc::JobQueue::DependencyTask.
Generally, the way to use this is to generate your dependency graph, then create your job queue, then start some jobs.
It's expected that you'll use asynchronous I/O via IO::Event, but that is not required. If you're using IO::Event, it sets up a timer event to start more jobs. It also changes $Event::DIED to unloop.
$Event::DIED
In addition to the parameters supported by Proc::JobQueue, the following construction parameters are used:
This should be a Object::Dependency object.
In addition to the methods inherited from Proc::JobQueue, this module adds:
This marks the $job as complete and a new job can start in its place.
