drools - Will logical facts be re-inserted when an object is updated but the updated fields from that object are not included in the rule that adds the fact? -


what want find out drools truth maintenance system re-insert logical fact (basically update existing 1 fresh object) when object part of rule inserting changed none of fields included in rule have changed?

below example show i'm talking about. lets have 2 classes below:

public class class1{     int x;     int y;     int z; } public class class2{     class1 class1;     int x;     int y; } public class logicalfact{     class2 class2; }

and next 2 example rules insert logical fact object class "logicalfact" :

rule "example1"     when         $class2 : class2(x > 20)             insertlogical(new logicalfact($class2)); end  rule "example2"     when         $class2 : class2(class1.x > 10, x > 20)             insertlogical(new logicalfact($class2)); end

lets y field class2 object ("class2") changed , z field class1 object on class2 object ("class2") pointing @ changed. in "example2" rule change in field y and/or change in field class1.z somehow cause rule re-evaluated , create , insert logical fact again scratch though these values not changed? different in "example1" case because uses x, evaluated if x class2 object changed?

an edge case setting same values again fields part of rule, in case insert logical fact again?

going further if logical facts being inserted again scratch re-evaluate rules used, though there not difference?

 /* based on "logicalfact" object inserting logical fact class   "anotherlogicalfact". */   rule "logical-fact-rule"      when logicalfact(...)               insertlogical(new anotherlogicalfact());  end

the rules in example simple might more complex including use of accumulate functions etc. re-evaluating rules rules nothing costly process.

probably of taken care of , truth maintenance system sticking created logical fact if there no change values on rules based. wanted ask opinion sure.

if turns out true best way approach it?
