[rules-users] How to reuse a result of a rule in an other rule

[mjohansen]

Basically, you can either update an object with the results of the first
rule, or create a new object.

Like:

rule "Hungry"
  when
    $person : Person(hoursSinceLunch>2 || donutsOnDesk==0 ||
candybarsInDrawer==0)
  then
    $person.setHungry(true);
    update($person);
end

rule "Food"
  when
    $person : Person(hungry==true)
  then
    $person.lookForFood()
end

or

rule "Hungry"
  when
    $person : Person(hoursSinceLunch>2 || donutsOnDesk==0 ||
candybarsInDrawer==0)
  then
     $hungry=new Hungry();
     $hungry.setPerson($person);
     insert($hungry);
end

rule "Food"
  when
    $person : Person()
    $hungry : Hungry(person==$person)
  then
    $person.lookForFood()
end
