10 Package Specification</h2>
|
|
|
11 <p>
|
|
|
12 This package specifies API for scheduling background tasks, or jobs. Jobs can be
|
|
|
13 scheduled for immediate execution, or for execution after a specified delay. Once
|
|
|
14 scheduled, jobs can be queried, canceled, or suspended. Rules can be attached to
|
|
|
15 jobs to indicate when they can run, and whether they can run simultaneously with other
|
|
|
16 jobs. This package also includes a generic locking facility that includes support for
|
|
|
17 detecting and responding to deadlock.
