       UML类图中有些标记很容易混淆，这里先复习下，请大家看下面这幅图：

二、应用框架：

       A、基本概念

       抽象（抽出共同之现象）——在同领域的程序中，常含有许多类别，这些类别有其共同点，我们将类别之共同结构抽离出来，称为抽象类别。其抽象之步骤是： 1、观察几个相似的类别；2、分辨它们的异同点；3、把它们的共同点抽离出来。

       衍生（与众不同之现象）——基于通用结构里的抽象类别，添加些特殊功能（扩展），使之成为具体类别，再诞生对象。

       所以抽象类别的存在目的，是要用其衍生子类别，而不是由它本身来诞生对象。由于抽象类别本身不诞生对象，所以有些方法并不完整。反之，类别之内的方法，皆是完整的，而且要用来诞生对象，就称它为具体类别。所谓不完整就是方法的方法体从缺，只有方法的描述。

       B、打造自己的专属应用框架之类图：

       C、打造自己的专属应用框架之编码实现：

      BaseApplication类源码如下：
