getDeduplicationInfo ()

Subclasses may need to override this to make duplication detection work.

getLastError ()

Returns: string

getMetadata ( $field=null)

getParams ()

Returns: array Parameters that specify sources, targets, and options for execution

Member Function Documentation

◆ allowRetries()

ThumbnailRenderJob::allowRetries ( )

Whether to retry the job.

Returns: bool

Reimplemented from Job.

Definition at line 173 of file ThumbnailRenderJob.php.

◆ hitThumbUrl()

ThumbnailRenderJob::hitThumbUrl	(	LocalFile	$file,
			$transformParams )

protected

Parameters

LocalFile	$file
array	$transformParams

Returns: bool Success status (error will be set via setLastError() when false)

Definition at line 82 of file ThumbnailRenderJob.php.

References File\getHandler(), File\getThumbUrl(), setLastError(), File\thumbName(), wfDebug(), and wfGetUrlUtils().

Referenced by run().

◆ run()

ThumbnailRenderJob::run ( )

Run the job.

If this method returns false or completes exceptionally, the job runner will retry executing this job unless the number of retries has exceeded its configured retry limit. Retries are allowed by default, unless allowRetries() is overridden to disable retries.

See the architecture doc for more information.

Returns: bool Return false to instruct the job runner to retry a failed job. Otherwise return true to indicate that a job completed (i.e. succeeded, or failed in a way that's deterministic or redundant).

Implements RunnableJob.
