Class MappedEnumType

java.lang.Object

to.etc.domui.hibernate.types.MappedEnumType

All Implemented Interfaces:

org.hibernate.usertype.ParameterizedType, org.hibernate.usertype.UserType

public class MappedEnumType
extends Object
implements org.hibernate.usertype.UserType, org.hibernate.usertype.ParameterizedType

This Hibernate user type allows mapping Java 5 enums onto fields where field values contain names that are invalid for enum labels (like 1, 6, 5, %fout). For this to work an enum must implement IDatabaseCodeEnum to map between database values and enum labels. This version works on varchar fields only.

This code works only when HibernateChecker.enhanceMappings() is called before use, or when the type of the property is uselessly repeated in Hibernate's config!!
