protected

Parameters

mixed

$recache

Returns

array|false

getLabelMap()

Wikibase\Lib\Store\AbstractTermPropertyLabelResolver::getLabelMap ( $recache = '' )

protected

Returns a map of labels to EntityIds for all Properties currently defined.

The information is taking from the cache if possible, and loaded from a MatchingTermsLookup if not.

			$recache = '' )

Parameters

string[]	$labels
string	$recache	Flag, set to 'recache' to fetch fresh data from the database.

Returns

EntityId[] a map of strings from $labels to the corresponding entity ID.

Implements Wikibase\DataModel\Services\Term\PropertyLabelResolver.

loadProperties()

Wikibase\Lib\Store\AbstractTermPropertyLabelResolver::loadProperties ( )

abstractprotected

Returns

EntityId[] Map of labels to EntityIds

Reimplemented in Wikibase\Lib\Store\Sql\Terms\CachedDatabasePropertyLabelResolver.
