 doFeed ( $class='', $limit=50)
 Similar to above, but packaging in a syndicated feed instead of a web page.
 
 doQuery ( $offset=false, $limit=false)
 Somewhat deprecated, you probably want to be using execute()
 
 execute ( $par)
 This is the actual workhorse.
 
 feedDesc ()
 
 feedItemAuthor ( $row)
 
 feedItemDesc ( $row)
 
 feedResult ( $row)

 feedTitle ()
 
 feedUrl ()
 
 fetchFromCache ( $limit, $offset=false)
 Fetch the query results from the query cache.

 Subclasses return an array of fields to order by here.
 
 getPageHeader ()
 The content returned by this function will be output before any 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.
 
 getRecacheDB ()
 Get a DB connection to be used for slow recache queries.
 
 getSQL ()
 For back-compat, subclasses may return a raw SQL query here, as a string.
 
 isCacheable ()
 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 ()
 Is this query expensive (for some definition of expensive)? Then we don't let it run in miser mode.
 
 isSyndicated ()

 linkParameters ()
 If using extra form wheely-dealies, return a set of parameters here as an associative array.
 
 openList ( $offset)
 
 preprocessResults ( $db, $res)

 tryLastResult ()
 Some special pages (for example SpecialListusers used to) might not return the current object formatted, but return the previous one instead.
 
 usesTimestamps ()
 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.
