Member Function Documentation

acquireAndInsertTerms()

Wikibase\Lib\Store\Sql\Terms\DatabasePropertyTermStoreWriter::acquireAndInsertTerms ( PropertyId  $propertyId, Fingerprint  $fingerprint  )

private

Acquire term in lang IDs for the given Fingerprint, store them in wbt_property_terms for the given property ID, and return term in lang IDs that are no longer referenced and might now need to be cleaned up.

Parameters

PropertyId	$propertyId
Fingerprint	$fingerprint

Returns

int[] wbpt_term_in_lang_ids to that are no longer used by $propertyId The returned term in lang IDs might still be used in wbt_property_terms rows for other property IDs or elsewhere, and this should be checked just before cleanup. However, that may happen in a different transaction than this call.

deleteTerms()

Wikibase\Lib\Store\Sql\Terms\DatabasePropertyTermStoreWriter::deleteTerms

(

PropertyId

$propertyId

)

deleteTermsWithoutClean()

Wikibase\Lib\Store\Sql\Terms\DatabasePropertyTermStoreWriter::deleteTermsWithoutClean ( PropertyId  $propertyId )

private

Delete wbt_property_terms rows for the given property ID, and return term in lang IDs that are no longer referenced and might now need to be cleaned up.

(The returned term in lang IDs might still be used in wbt_property_terms rows for other property IDs, and this should be checked just before cleanup. However, that may happen in a different transaction than this call.)
