public function SearchApiAttachmentsLinksAlterSettings::alterItems in Search API attachments 7

Alter items before indexing.

Items which are removed from the array won't be indexed, but will be marked as clean for future indexing. This could for instance be used to implement some sort of access filter for security purposes (e.g., don't index unpublished nodes or comments).

Parameters

array $items: An array of items to be altered, keyed by item IDs.

Overrides SearchApiAttachmentsAlterSettings::alterItems
