public static function Utility::getDataTypeInfo in Search API Solr 8

Same name and namespace in other branches

1. 8.3 src/Utility/Utility.php \Drupal\search_api_solr\Utility\Utility::getDataTypeInfo()
2. 8.2 src/Utility/Utility.php \Drupal\search_api_solr\Utility\Utility::getDataTypeInfo()
3. 4.x src/Utility/Utility.php \Drupal\search_api_solr\Utility\Utility::getDataTypeInfo()

Retrieves Solr-specific data for available data types.

Returns the data type information for both the default Search API data types and custom data types defined by hook_search_api_data_type_info(). Names for default data types are not included, since they are not relevant to the Solr service class.

We're adding some extra Solr field information for the default search api data types (as well as on behalf of a couple contrib field types). The extra information we're adding is documented in search_api_solr_hook_search_api_data_type_info(). You can use the same additional keys in hook_search_api_data_type_info() to support custom dynamic fields in your indexes with Solr.

Parameters

string|null $type: (optional) A specific type for which the information should be returned. Defaults to returning all information.

Return value

array|null If $type was given, information about that type or NULL if it is unknown. Otherwise, an array of all types. The format in both cases is the same as for search_api_get_data_type_info().
