"If strict
encapsulation is used where even private methods used a standard get<Object>
method, you can delay the instantation of the object until it is truly necessary. This concept
is particularly important for value objects or other objects used as data transport
across a network. This practice minimizes the amount of RMI serialization overhead as
well as reducing network traffic."

This is taken from a book. I dont understand how encapsulation where private attributes are accessed thru getters will result in lazy instantiation and how it helps avoid RMI serialization? Please throw some light on this.

It doesn't result in lazy instantiation, but it's a prerequisite; i.e., if you're not going to create an object until it's needed, then you have to know when its needed, and therefore you have to always access it via a getter method.

The part about RMI and serialization follows naturally if creating an object requires fetching data via these mechanisms, as might be the case if the objects we're talking about are EJBs.
