指令数据采集（四）--指令的条件处理

例如条件：（A=B）&&(B>C)

条件使用的是条件组的概念，单独的条件也是一个条件组例如，A和B是条件关联，B和C也是条件关联，（A=B）和(B>C)是组关联，那么我建的对象如下

  1 public class GroupCondition implements Cloneable{
  2 
  3     //star 左边所有的判断
  4     /**
  5      * A左边的属性判断
  6      */

  8     /**
  9      * 放入的条件判断 属性和属性的条件判断
 10      */
 11     private IConditionOperation iConditionOperation;
 12     /**
 13      * B右边的属性判断
 14      */
 15     private Param paramB;
 16     //end 右边所有的判断
 17     /**

代码解析

1.使用递归的关系进行实现条件A作为paramA,条件B作为paramB，中间的接口iConditionOperation来进行条件判断

条件判断的代码

1.接口

 1 public interface IConditionOperation {
 2 
 3     /**
 4      * 组比较的成员
 5      * @param paramA
 6      * @param paramB
 7      * @return
 8      */
 9     boolean operation(Param paramA,Param paramB);
10 
11     /**
12      * 组关系和组关系之间的逻辑判断
13      * @param flagA
14      * @param flagB
15      * @return
16      */
17     boolean operationLogic(boolean flagA,boolean flagB);
18 }

分成两个，组内比较，和组和组之间比较实现，组和组之间的条件判断就是and或者or进行条件判断
