abstract public Schema::getFieldTypeMap() Returns a mapping of Drupal schema field names to DB-native field types. Because different field types do not map 1:1 between databases, Drupal has its own normalized field type names. This function returns a driver-specific mapping table from Drupal names to the native names for each database. Return value array An array of Schema API field types to driver-specific field types.
