4.15. Conflict Resolver Strategy Example

Each rule has a default value of 0, the higher the value the higher the priority. To illustrate this, a rule is added to print the account balance. The goal is for the rule to be executed after all the debits and credits have been applied for all accounts. This is done by assigning a negative salience to this rule so that it fires after all rules with the default salience 0.

rule "Print balance for AccountPeriod"
        salience -50
    when
        ap : AccountPeriod()
        acc : Account()        
    then
        System.out.println( acc.accountNo + " : " + acc.balance );    
end
