This second test shows how to use enumerated values and user defined data types as attributes.

• Enums:
  In the TravelDescription class we define the enumeration:

   enum AccommodationTypes  { OneStar, TwoStars, ThreeStars, HolidayFlat, FourStars, FiveStars};
   

  for the accomodation attribute. To manage that attribute we only have to modify the TravelDescription.hbm.xml with the following code:

    ...
          <property name="Accommodation" column="Accommodation">
                  <type name="es.ucm.fdi.gaia.jcolibri.connector.databaseutils.EnumUserType">
                          <param name="enumClassName">es.ucm.fdi.gaia.jcolibri.test.test2.TravelDescription$AccommodationTypes</param>
          </type>
          </property>
          ...
   

  The EnumUserType class is a utility class of the connector that allows managing Enums. It recieves the class name of you enum as parameter.
• User defined data types:
  To create your own data type implement the jcolibri.connector.TypeAdaptor interface. MyStringType.java is a simple example were we are wrapping a string. You have to define the toString(), fromString() and equals() methods. That way the value of your data type will be mapped using a string representation in the presistence media.
  In this example we have typed the "Hotel" attribute of the description as "MyStringType. To manage the attribute we have to modify the TravelDescription.hbm.xml file with:

          <property name="Hotel" column="Hotel">
                  <type name="es.ucm.fdi.gaia.jcolibri.connector.databaseutils.GenericUserType">
                          <param name="className">es.ucm.fdi.gaia.jcolibri.test.test2.MyStringType</param>
        </type>
          </property>
   

  The GenericUserType class is the utility class that allows to manage TypeAdaptor implementations in the data base connector.
