public enum SurrogateColumnType extends Enum<SurrogateColumnType>
Enum defining the types of surrogate columns for a class. The
fieldNumber
is used where we need to pass a list of fields to be fetched, or updated, and want to include surrogate fields. The normal fields of a class are numbered from 0 upwards, so we use negative numbers for the surrogates.
