public class BaseEnumConverter<E extends Enum<E>>
extends Object
implements org.hibernate.usertype.UserType

This is a base class that implements Hibernate's UserType. The class must be subclassed in order to be used as a UserType. To create a UserType that will convert between a VARCHAR and your java enumeration, say MyEnum, do the following:

 public class MyEnumConverter extends BaseEnumConverter
 {
        public MyEnumConverter()
        {
                super(my.package.MyEnum.class);
        }
 }
 

MyEnumConverter will be able to automatically convert types in MyEnum to and from database VARCHAR's.
