	__construct (IContextSource $context, $userName, $search, $including, $showAll, LinkRenderer $linkRenderer)

	getDefaultQuery ()
	Get an array of query parameters that should be put into self-links.

	getDefaultSort ()
	The database field name used as a default sort order.

	getForm ()

	getIndexField ()
	Returns the name of the index field.If the pager supports multiple orders, it may return an array of 'querykey' => 'indexfield' pairs, so that a request with &order=querykey will use indexfield to sort. In this case, the first returned key is the default.Needless to say, it's really not a good idea to use a non-unique index for this! That won't page right.The pager may paginate on multiple fields in combination. If paginating on multiple fields, they should be unique in combination (e.g. when paginating on user and timestamp, rows may have the same user, rows may have the same timestamp, but rows should all have a different combination of user and timestamp).Examples: Always paginate on the user field: 'user' Paginate on either the user or the timestamp field (default to user): [ 'name' => 'user', 'time' => 'timestamp', ] Always paginate on the combination of user and timestamp: [ [ 'user', 'timestamp' ] ] Paginate on the user then timestamp, or the timestamp then user: [ 'nametime' => [ 'user', 'timestamp' ], 'timename' => [ 'timestamp', 'user' ], ] Returns string\|string[]\|array[] Stable to override Stable to override

◆ reallyDoQuery()

ImageListPager::reallyDoQuery	(	$offset,
		$limit,

	)

Override reallyDoQuery to mix together two queries.

Note: $asc is named $descending in IndexPager base class. However it is true when the order is ascending, and false when the order is descending, so I renamed it to $asc here.

Parameters
