|
* This class provides functions to manage backgroundjobs in ownCloud
|
|
|
|
*
|
|
|
|
* There are two kind of background jobs in ownCloud: regular tasks and
|
2012-08-09 21:04:04 +04:00
|
|
|
* queued tasks.
|
2012-08-09 02:01:06 +04:00
|
|
|
*
|
|
|
|
* Regular tasks have to be registered in appinfo.php and
|
|
|
|
* will run on a regular base. Fetching news could be a task that should run
|
|
|
|
* frequently.
|
|
|
|
*
|
2012-08-09 21:04:04 +04:00
|
|
|
* Queued tasks have to be registered each time you want to execute them.
|
|
|
|
* An example of the queued task would be the creation of the thumbnail. As
|
|
|
|
* soon as the user uploads a picture the gallery app registers the queued
|
|
|
|
* task "create thumbnail" and saves the path in the parameter instead of doing
|
|
|
|
* the work right away. This makes the app more responsive. As soon as the task
|
|
|
|
* is done it will be deleted from the list.
