org.jboss.portal.jems.hibernate
Class MagicString

java.lang.Object
  org.jboss.portal.jems.hibernate.MagicString

All Implemented Interfaces:: java.io.Serializable, org.hibernate.usertype.UserType

public class MagicString
extends java.lang.Object
implements org.hibernate.usertype.UserType, java.io.Serializable

An hibernate custom type that handles the fact that oracle stores an empty string as null. That types changes the semantic of string with the fact that a returned null string is equals to an empty string.

I did not found a good name for that class so I choosed MagicString but it has nothing magic.
