This is used to mark up links when displaying +a page. If the same link appears more than once on any page, +then it only has to be looked up once. In most cases, link +lookups are done in batches with the LinkBatch class, or the +equivalent in Parser::replaceLinkHolders(), so the link +cache is mostly useful for short snippets of parsed text +(such as the site notice), and for links in the navigation +areas of the skin. + +The link cache was formerly used to track links used in a +document for the purposes of updating the link tables. This +application is now deprecated. + + |
