comment-Value Object Participants v2-1 From the [PLoP 2006] writers' workshop: None. Dirk Riehle Dirk Riehle 2006-10-24 08:02:57.752 2006-10-24 08:02:52.384 Value Object Participants v2 The ~~Client~~ class uses Value instances like built-in datatypes (to the extent that this is possible with your implementation language). Whenever the Client wants to change the value of one of its attributes, it replaces the attribute object rather than changing it. You write code like {code}attr = attr.calculate();{code} rather than {code}attr.calculate();{code} The ~~Value~~ class represents a domain-specific value type. It is implemented such that Value instances are immutable objects, meaning that its instances cannot change their state. Rather, as the result of some computation, a new Value instance with the desired internal state is returned.
