Intelligent Value Objects

Example: User Groups

• Example class diagram for an intelligent UserGroup VO

• VO contains standard getters and setters
• Additionally: Static inner factory class for calling coreservice methods and processing XML transformations
• Additionally: object methods that call the factory methods
  • Easier handling of VO objects

• Advantages:
  • User does not have to struggle with XML transformation and coreservice methods
  • Less code

Suggestions

• Constructor for retrieving object?

Outcome

• Change Exception handling (RuntimeException instead of Exception)
• Make all coreservice methods object-related, also the retrieve method. Factory is only private.
• Find a more generic way for marshalling/unmarshalling methods
