Object Handler - value object and object

[Candy Chiu]

Hi,

I noticed in the account example that two objects were created per entity.   For example, to create a Customer,

    boost::shared_ptr <ObjectHandler::ValueObject> valueObject(
        new AccountExample::CustomerValueObject(objectID, name, age, false));

    boost::shared_ptr<ObjectHandler::Object> object(
        new AccountExample::CustomerObject(valueObject, name, age, false));

first creates a ValueObject, then later passes it to an Object.

Would any one provide a quick explanation of the design philosophy behind creating two objects per entity?

Thank you very much.

The ValueObject captures the inputs to the Object's constructor.  The  
main use of the ValueObject is to support serialization.  The  
ValueObject is compatible with the boost::serialization and can be  
serialized natively and after serialization can be used to reconstruct  
the original Object.
