Parameters

EntityId	$entityId
string	$termType
string	$languageCode

Returns

string|false|null The term, or false of that term is known to not exist, or null if the term was not yet requested via prefetchTerms().

prefetchTerms()

Wikibase\Lib\Store\Sql\Terms\TermStoresDelegatingPrefetchingItemTermLookup::prefetchTerms	(	array	$entityIds,
		array	$termTypes,
		array	$languageCodes
	)

Loads a set of terms into the buffer.

The source from which to fetch would typically be supplied to the buffer's constructor.

Parameters

EntityId[]	$entityIds
string[] | null	$termTypes	The desired term types; null means all.
string[] | null	$languageCodes	The desired languages; null means all.
