[condition][]规则开始=$list : ArrayList()

[condition][]规则开始=$list : ArrayList()  解释：  需要在java类中写上如下才能满足条件：

            WorkingMemory workingMemory = ruleBase.newStatefulSession();
            List list= new ArrayList();
            workingMemory.insert( list );
            workingMemory.fireAllRules();
