Parameter
Passing
One beauty of RMI is the ability to pass Java objects back and forth.
This is really what makes RMI great, because our program can act over multiple
computers over a network. Without this, all we really have is a program
that passes bytes over a socket.
- We have two options when sending parameters. Consider the implications:
- Non-remote: we pass a copy of the parameter from one instance to another.
- Remote: Just like our ChatImpl, we pass a stub to the client and we keep everything updated in one place. These objects must implement the Remote interface.
