Value Objects
Look at that : http://www.infoq.com/presentations/Value-Objects-Dan-Bergh-Johnsson
From first part, I’ll retain :
Candidates for Domain Logic Value Objects :
Strings with format limitations – eg:
- Name
- OrderNumber
- Zipcode
Integers with limitations – eg:
- Percentage with a range of 0-100%
- Quantity (>= 0)
Explicit methods arguments/return – eg:
- Double becomes Price
- Map<String,List<String>> becomes LoggingAttempts
Second part goes high… I di not grasp the whole thing – YET !
