protected TermStorageSchema::getSharedTableFieldSchema(FieldStorageDefinitionInterface $storage_definition, $table_name, array $column_mapping)
Gets the schema for a single field definition.
Entity types may override this method in order to optimize the generated schema for given field. While all optimizations that apply to a single field have to be added here, all cross-field optimizations should be via SqlContentEntityStorageSchema::getEntitySchema() instead; e.g., an index spanning multiple fields.
Parameters
\Drupal\Core\Field\FieldStorageDefinitionInterface $storage_definition: The storage definition of the field whose schema has to be returned.
string $table_name: The name of the table columns will be added to.
string[] $column_mapping: A mapping of field column names to database column names.
Return value
array The schema definition for the table with the following keys:
- fields: The schema definition for the each field columns.
- indexes: The schema definition for the indexes.
- unique keys: The schema definition for the unique keys.
- foreign keys: The schema definition for the foreign keys.
Throws
\Drupal\Core\Field\FieldException Exception thrown if the schema contains reserved column names.
