protected function SearchApiEtDatasourceController::setLanguage in Search API Entity Translation 7.2

Sets language of specific fields on an EntityMetadataWrapper object.

This is essentially a copy of search_api_extract_fields(), just slightly adapted to set language on the wrapper fields instead of extracting them.

Parameters

EntityMetadataWrapper $wrapper: The wrapper on which fields to set language on.

array $fields: The fields to set language on, as stored in an index. I.e., the array keys are field names, the values are arrays with at least a "type" key present.

array $langcode: A code of the language to set to wrapper fields.

Return value

array The $fields array with additional "value" and "original_type" keys set.
