| 1. | Refers to the ability of one class child class to
，指的是一个类（子类） |
| 2. | Changes to a parent class will be reflected in all child classes
父类的变化将在所有的子类中体现出来。 |
| 3. | But the writer of this child class needs to understand pretty accurately exactly what
已经做了什么；而且除非通过在子类中完全重写 |
| 4. | In an aggregation relationship , the child class instance can outlive its parent class
在一个聚合关系中，子类实例可以比父类存在更长的时间。 |
| 5. | You can use tree notation when there are two or more child classes , as in figure 4 , except that the inheritance lines merge together like a tree branch
当存在两个或更多子类时，如图4中所示，除了继承线象树枝一样混在一起外，你可以使用树形记号。 |
| 6. | Contains a procedure that demonstrates how to use class designer to cause a member in a child class to override provide a new implementation for a member inherited from a base class
包含如何使用类设计器使子类中的成员重写（提供新的实现）从基类继承的成员的演示过程。 |
| 7. | The composition aggregation relationship is just another form of the aggregation relationship , but the child class s instance lifecycle is dependent on the parent class s instance lifecycle
组合聚合关系是聚合关系的另一种形式，但是子类实例的生命周期依赖于父类实例的生命周期。 |
| 8. | To model inheritance on a class diagram , a solid line is drawn from the child class the class inheriting the behavior with a closed , unfilled arrowhead or triangle pointing to the super class
为了在一个类图上建模继承，从子类（要继承行为的类）拉出一条闭合的，单键头（或三角形）的实线指向超类。 |
| 9. | In other words , the bankaccount class provides the abstract operation signature of withdrawal and the two child classes of checkingaccount and savingsaccount each implement their own version of that operation
换句话说， bankaccount类使用withdrawal规定抽象操作，并且checkingaccount和savingsaccount两个子类都分别地执行它们各自版本的操作。 |
| 10. | In discussing the service - based testing technologies , the block ’ s branch testing pattern is put forward by decomposing the complicated conditions of the class source codes . in discussing the state - based testing technologies , the idea of extending the states of child class is put forward . according to idea of the object state model , the object state testing model is put forward based on the source codes , which realize to construct the test - related object state sketches from the source codes
在讨论基于服务的测试技术时,我们提出了对类的源代码中的复杂条件进行分解的块分支测试模式;在讨论基于状态的测试技术时,本文提出了将子类状态进行展开扩充的思想,根据对象状态模型的思想提出了基于源代码的对象状态测试模型,实现从源代码构造出与测试相关的对象状态草图。 |
