<a name="gdbus-interface-org-freedesktop-UDisks2-Job"></a><h2>Description</h2>
<p>
Some operations may take a long time (hours) to complete, that
is, to actually send the D-Bus reply message back. One example
of such an operation is the
<a class="link" href="gdbus-org.freedesktop.UDisks2.Block.html#gdbus-method-org-freedesktop-UDisks2-Block.Format" title="The Format() method">Format()</a> method that is used to
format a block device.
</p>
<p>
When such operations are initiated, a job object implementing
this interface may be created so the progress can be tracked by
the caller (and also other observers).
</p>
<p>
The object(s) that a job affects (such as block devices or
drives) can be determined by looking at the
<a class="link" href="gdbus-org.freedesktop.UDisks2.Job.html#gdbus-property-org-freedesktop-UDisks2-Job.Objects" title='The "Objects" property'>"Objects"</a> property. Among other
things, this can be used to draw a spinner in the user interface
next to e.g. an icon for the drive or device in question.
</p>
<p>
The <a class="link" href="gdbus-org.freedesktop.UDisks2.Job.html#gdbus-property-org-freedesktop-UDisks2-Job.Operation" title='The "Operation" property'>"Operation"</a> property is used to
convey the type of job currently in progress.
</p>
<p>
The user id of the user who started the job is set in the
<a class="link" href="gdbus-org.freedesktop.UDisks2.Job.html#gdbus-property-org-freedesktop-UDisks2-Job.StartedByUID" title='The "StartedByUID" property'>"StartedByUID"</a> property.
</p>
<p>
A job <span class="emphasis"><em>may</em></span> convey how much progress has been
made, see the <a class="link" href="gdbus-org.freedesktop.UDisks2.Job.html#gdbus-property-org-freedesktop-UDisks2-Job.Progress" title='The "Progress" property'>"Progress"</a> and
<a class="link" href="gdbus-org.freedesktop.UDisks2.Job.html#gdbus-property-org-freedesktop-UDisks2-Job.ProgressValid" title='The "ProgressValid" property'>"ProgressValid"</a> properties.
</p>
<p>
When a job completes, the <a class="link" href="gdbus-org.freedesktop.UDisks2.Job.html#gdbus-signal-org-freedesktop-UDisks2-Job.Completed" title='The "Completed" signal'>"Completed"</a> signal
is emitted.
</p>
<p>
A job may or may not be cancelable, see the
<a class="link" href="gdbus-org.freedesktop.UDisks2.Job.html#gdbus-property-org-freedesktop-UDisks2-Job.Cancelable" title='The "Cancelable" property'>"Cancelable"</a> property. To cancel a
job use the <a class="link" href="gdbus-org.freedesktop.UDisks2.Job.html#gdbus-method-org-freedesktop-UDisks2-Job.Cancel" title="The Cancel() method">Cancel()</a> method. This
will cause the job to complete (with <em class="parameter"><code>success</code></em> set to <code class="constant">FALSE</code>) and
the D-Bus method used to initiate the operation to return,
usually returning the
<code class="literal">org.freedesktop.UDisks2.Error.Cancelled</code>
error. Once cancellation is requested it may take some time before
the job is actually completed as there might be ongoing I/O.
