Class EmptyStringUserType

java.lang.Object
  com.atlassian.crowd.util.persistence.hibernate.EmptyStringUserType

All Implemented Interfaces:

org.hibernate.usertype.UserType

public class EmptyStringUserType
extends Object
implements org.hibernate.usertype.UserType

This class will convert NULL values retrieved from the database into EMPTY_STRING. This is required since Oracle treats EMPTY_STRING as NULL. (http://download-west.oracle.com/docs/cd/B12037_01/server.101/b10759/sql_elements005.htm) This class will not change how values are stored into the database. Code was based on: https://www.hibernate.org/169.html (2nd example)
