Detailed Description

Job to update link tables for pages.

This job comes in a few variants:

a) Recursive jobs to update links for backlink pages for a given title. These jobs have (recursive:true,table:

set.
b) Jobs to update links for a set of pages (the job title is ignored). These jobs have (pages:(<page id>="">:(<namespace>,<title>),...) set.
c) Jobs to update links for a single page (the job title) These jobs need no extra fields set.

◆ getDeduplicationInfo()

RefreshLinksJob::getDeduplicationInfo ( )

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

The resulting map conveys everything that makes the job unique. This is only checked if ignoreDuplicates() returns true, meaning that duplicate jobs are supposed to be ignored.

Returns: array Map of key/values

Implements IJobSpecification.
