There's no tutorial guide or anything like that. The basic procedure
is very easy: implement the "jess.Strategy" interface, then use
(set-strategy <classname>) to load it into Jess. There's really just
the one compare() method to write; it's supposed to implement the
"spaceship operator" (ie., comparison that returns negative, 0, or
positive to indicate how the activations should be ordered.) As long
as your ordering is internally consistent, it can be anything you
want. You can even ignore salience if you'd like, so that a perfectly
valid implementation could be something as simple as
/**
* A Jess conflict resolution strategy that gives priority to
* rules with more patterns.
*/
public SizeStrategy implements jess.Strategy {
public int compare(Activation a1, Activation a2) {
return a1.getToken().getSize() - a2.getToken().getSize();
}
public String getName() { return "size"; }
}
