我对这些计划了解得对吗

图1：

许可证

，

个人许可证

，

业务许可证

正常，

计费

必须如下所示：

公共类计费{
私人Lisense许可证；
公共计费（许可证）{
this.license=许可证；
}
公帑{
//一些代码
此.license.calcFee（）；
//一些代码
}
公共许可证（许可证）{
this.license=许可证；
}
}

它看起来像，它允许您定义一系列算法（

许可证

），将它们放入一个单独的类（

个人许可证

，

业务许可证

），并使它们的对象可互换。主要功能是

Billing

类只知道它有一些许可证对象，它可以

calcFee

，而不知道具体的实现。稍后，为了支持新的许可证类型，您将创建

许可证

的新实现，并且不会修改

计费

图2：

User1

，

User2

，

User3

，必须是类似的，并具有相应的U*OP：

公共类用户1{
私人U1Ops U1Ops；
公共用户1（U1Ops U1Ops）{
此.u1Ops=u1Ops；
}
}
//类的使用
OPS=新OPS（）；
User1 User1=新User1（ops）；
User2 User2=新User2（ops）；

看起来像是接口隔离原则的示例，它指出不应强制任何客户端（

User1

，

User2

，

User3

）依赖于它不使用的方法（

User1

只需要

op1（）

）

图3：

与前面的示例一样，必须使用

User

实例字段实现关联。这些图表演示了（上面是坏习惯，下面是好习惯）。根据它，

用户

必须只知道一些抽象的

权限

接口，而不知道具体的实现，

权限

类只知道它实现的

权限

接口。使用此原则，

实体

模块创建自己的抽象级别（）-

权限

接口和使用它的

授权人。与之相关的术语通常在java框架（例如）中用于低层模块
我不知道如何回答您的问题。您想知道模式是否与您的代码匹配，或者模式背后的想法是什么？请详细说明你的具体问题。@Bram是的，你说得对！模式与我的代码匹配吗？因为我想如果他们这样做了，我就明白他们是对的，我想我明白了。你知道，我认为如果Billing
使用图片1中的License
，这意味着我们使用PersonalLicense
或BusinessLicense
）的License
的新实例（BusinessLicense
），在Billing
内键入Billing
，但实际上我们做了下一件事：Billing b=新的账单（new PersonalLicense（））
和Billing b=new Billing（new BusinessLicense（））
。简而言之，我们为每个许可证
实现创建新实例，并将它们放在Billing
中，它只知道它有一些许可证
对象，对吗？
