Default Value objects

Hi,

All over the book, especially when asn1 and *Spec classes are discussed , they are referred to as "value objects". I'm kinda confused about what we call "value object" and what we do not.

In my understanding SubjectPublicKeyInfo from org.bouncycastle.asn1.x509 package (as well as other Spec classes) can hold enough information in it to be (algorithmidentifier + publickey bits) used in encrypt/decrypt operations, so I really wonder what is meant by "value object" in the book.

Would be glad if anyone can clarify the difference, hopefully by example


Thanks
Ray

Value object is a term from Object Oriented programing. In this case it just means the object carries a set of values describing something and is immutable.

Regards,

David
