Well, first of all, this isn't quite how Java works. The line
Rete r2 = r1;
makes r2 a copy of the -pointer- r1. Both variables refer to the same
Rete object afterwards.
The Rete class doesn't implement the clone() method or the Cloneable
interface, so there's no direct way to make a copy. I have no plans to
support this in the future, either.
What you could do in Jess 6.0a3 is use the bsave and bload commands to
create copies of a Rete object.
Rete r1 = new Rete();
r1.executeCommand("(batch /x.clp)");
r1.executeCommand("(bsave myImage)");
Rete r2 = new Rete();
r2.executeCommand("(bload myImage"));
r2 is now a copy of r1, except for any open files or JessEvent
listeners you may have registered in r1. This is probably no faster
than simply reloading the rules into the new copy, but perhaps you
have something in mind besides speed.
