Question

下面是我的课：

    public class NumberDetails {

        private String a ; 
        private String b;
        private String c;
        private String status;

        private String result;

         // getters and setters
        }

初始化值状态：302，a =“ A”，b =“ 2”

我必须运用逻辑：

if(status=302){
    result = a+b; 

}

如何在.drl文件中编写此内容？

rule "302 case"
when 
    numberObject: NumberDetails(status==302)
then

    numberObject.setResult(numberObject(a)+numberObject(b)); // I know this is wrong but how to write it ?
end

您可以使用private fun isNameValid(name: String?): LiveData<Boolean> { var namesValid = false if (!name.isNullOrEmpty()) { namesValid = true } val mediatorLiveData: MediatorLiveData<Boolean> = MediatorLiveData() mediatorLiveData.value = namesValid return mediatorLiveData }方法来获取firstNamesValid = Transformations.switchMap(firstName) { firstName -> isNameValid(firstName) } lastNamesValid = Transformations.switchMap(lastName) { lastName -> isNameValid(lastName) }中的值。例如，您可以将规则写为：

getter and setter

Drools：Drl文件变量
