Is it will add some thing to each Entity ?
Yes, I would assume that's what it will do too.
(You may notice that we have now answered two questions in this thread simply on the basis of looking at the description of how something works, without actually knowing anything at all about the real details of how it works. We might be wrong, but in real life it doesn't matter, since all we have to do is to remember not to make the entity classes final and we can go on our way designing and implementing systems.)
