The answer depends on what the results are, precisely. For example, if
your Java code wants to know about the existence of certain facts
after a run, it can either call Rete.listFacts() to get an iterator
over all the facts, or it can use a defquery to find only specific
facts.
If, on the other hand, you have a rule named compute-final-answer and
on its RHS it calculates a result like "42", then yes, that rule's RHS
should call (store RESULT 42) and the Java code should call
Rete.fetch("RESULT").intValue(null).
Does that answer your question?
