what is the difference between no-loop and lock-on-active in drools

Question

Here is an example of a rule that uses \"no-loop\":

rule \"Even Number Rule\"   
dialect \"java\"  
no-loop  
      when  
       n : Number( number !=0 &         


        

Answer 1

Long story short:

• no-loop: avoid the re-activation of a rule caused by the RHS of that SAME rule.
• lock-on-active: avoid the re-activation of a rule NO MATTER what the cause is.
