RE: JESS: Defglobal function.
Ernest,
Ok, I will use reset() method instead of resetToMark() at the end of each loop.
My question is,
The global varible(a fuzzyVariable)'s terms get changed due to the different
input in each loop. Without recreating it, how can I update it in the engine
from Java in each loop?
Thanks,
Andrew

RE: JESS: Defglobal function.
Nothing is utterly wrong, but I'm not sure it makes sense to reuse the Rete
object for each loop iteration without either (1) calling "clear", to
completely start over, or (2) moving some of the stuff out of the loop, like
the batch file. The resetToMark() call is removing all the facts except for the
(initial-fact) -- it seems like you could just call "reset". And of course once
you've defined the defglobal with a particular object as its initial value,
that variable doesn't need to be recreated, so the defglobal can move out of
the loop as well.

RE: JESS: Defglobal function.
Ernest,
Thanks a lot for helping me here!
Let me clarify what I try to do:
The internal state of the global veriable(fuzzyVariable) is keep changing
because the defination of the fuzzy term gets changed according to the external
input.
My code is like,
---
WorkingMemoryMark marker;
engine = new FuzzyRete();
Defglobal dg;
FuzzyVariable var = new FuzzyVariable ("value" 0 100 "percentage");
engine.reset();
marker = engine.mark();
while( input){
var.addTerm("low", ZFuzzySet(input);
var.addTerm("high", SFuzzySet(input);
dg = new Defglobal("*v*", new Value(var));
engine.addDefglobal(dg);
engine.batch("x.clp"); //x.clp will reference the global variable
if (engine.run() >1){
//do something
}
engine.clearStorage();
engine.resetToMark(marker)
}
--
Will the defglobal part work?
Thanks a lot!
Andrew

Re: JESS: Defglobal function.
Hi Andrew,
I'm not sure how subtle your question actually is, because there may
be a major issue with accomplishing what you're after here. The
initial value of a defglobal is stored exactly as it appears in the
definition of the defglobal; if the initial value is a function call,
then that function call itself is stored. This is so that when you
call (reset), the function call can be invoked to initialize the
defglobal to an appropriate new value at that time.
In any case, the point is that the function call has to be stored as
Jess code, so the code that creates the FuzzyVariable itself has to be
expressed as a Jess function call no matter what. If you want to
express exactly what you've shown here without any Jess code, then I'm
afraid you're out of luck!
If, on the other hand, it's OK for the initial value of the defglobal
to be one, specific object created in Java, then you could just create
the FuzzyVariable in Java (including the "addTerm" calls) and then
call something like
FuzzyRete engine = ...
FuzzyVariable var = ...
Defglobal dg = new Defglobal("*v*", new Value(var));
engine.addDefglobal(dg);

I am wondering how I could do the same thing totally from Java using
Jess API.
