Public Member Functions

 __construct (NamespaceInfo $namespaceInfo, IConnectionProvider $dbProvider, LinkBatchFactory $linkBatchFactory)
 
 formatResult ( $skin, $result)
 
 getQueryInfo ()
 Subclasses return an SQL query here, formatted as an array with the following keys: tables => Table(s) for passing to Database::select() fields => Field(s) for passing to Database::select(), may be * conds => WHERE conditions options => options join_conds => JOIN conditions.
 
 isSyndicated ()
 Sometimes we don't want to build rss / atom feeds.
 
 preprocessResults ( $db, $res)
 
 reallyDoQuery ( $limit, $offset=false)
 Run the query and return the result.
 
- Public Member Functions inherited from MediaWiki\SpecialPage\QueryPage
 delete (LinkTarget $title)
 Remove a cached result.
 
 deleteAllCachedData ()
 Remove all cached value This is needed when the page is no longer using the cache.
 
 doQuery ( $offset=false, $limit=false)
 Somewhat deprecated, you probably want to be using execute()
 
 execute ( $par)
 This is the actual workhorse.
 
 fetchFromCache ( $limit, $offset=false)
 Fetch the query results from the query cache.
 
 getCachedTimestamp ()

 Is the output of this query cacheable? Non-cacheable expensive pages will be disabled in miser mode and will not have their results written to the querycache table.
 
 isCached ()
 Whether or not the output of the page in question is retrieved from the database cache.
 
 isExpensive ()
 Should this query page only be updated offline on large wikis?
 
 recache ( $limit, $unused=true)
 Clear the cache and save new results.

 Does this query return timestamps rather than integers in its 'value' field? If true, this class will convert 'value' to a UNIX timestamp for caching.

Member Function Documentation

◆ formatResult()

◆ getGroupName()

MediaWiki\Specials\SpecialShortPages::getGroupName ( )
protected

Under which header this special page is listed in Special:SpecialPages See messages 'specialpages-group-*' for valid names This method defaults to group 'other'.

Stability: stable

◆ getOrderFields()

MediaWiki\Specials\SpecialShortPages::getOrderFields ( )
protected

Subclasses return an array of fields to order by here.

Don't append DESC to the field names, that'll be done automatically if sortDescending() returns true.

Stability: stable

◆ getQueryInfo()

MediaWiki\Specials\SpecialShortPages::getQueryInfo ( )

Subclasses return an SQL query here, formatted as an array with the following keys: tables => Table(s) for passing to Database::select() fields => Field(s) for passing to Database::select(), may be * conds => WHERE conditions options => options join_conds => JOIN conditions.

Note that the query itself should return the following three columns: 'namespace', 'title', and 'value'. 'value' is used for sorting.

These may be stored in the querycache table for expensive queries, and that cached data will be returned sometimes, so the presence of extra fields can't be relied upon. The cached 'value' column will be an integer; non-numeric values are useful only for sorting the initial query (except if they're timestamps, see usesTimestamps()).

Don't include an ORDER or LIMIT clause, they will be added.

Returns
array
