5 C ++ inheritance Design for ibm rsa (IBM Rational Software Architect) V8

In fact, the entire seriesArticleI want to give myself a memo, but I have a poor memory and post a message. It is also convenient for students who love learning.

Next, let's talk about the class design of C ++ and generate C ++.Code:

4 C ++ class diagram converted from ibm rsa (IBM Rational Software Architect) V8 modeling learning to C ++ code

In the previous article, I have created a class chart that can generate C ++ struct code. Then I create a class inheritance and create a new class. The base class uses the my_struct struct. The new class is derived_my_struct and a member is added as d_mem and char, the whole process class design is only a method of use, and examples, does not represent any practical significance.

 

Save all, double-click tc1.tc in "Project Resource Manager", and click "run" to generate C ++ code. As follows:

 

No problem. Everything is OK.

Now, the inheritance relationship diagram is actually not as easy as you think. Let's look at it.

Select "select board" and select "Generalized relationship ":

The inheritance relationship between the two classes created by the connection:

 

Save all the files, select tc1.tc, and click Run to generate the C ++ inheritance code, as shown below:

It is strange that the generated code is private inheritance. What should we do if we want to inherit in total? Is there a way to create a common inheritance and protect the inheritance in this general relationship?

Haha, of course there is a solution.

The operation is as follows.

Select the inherited arrow and click "constructor" in the attribute column below to add a type. Of course, only one type is available, that is, cpp_generalization, how to translate it into Chinese? -- C ++ generalization? It doesn't matter. Click OK:

 

Click "advanced" in the "attribute bar", and the following C ++ attributes will be displayed:

Do not modify isvirtual. Keep it false. If it is true, it means virtual inheritance. The generalized type (generalizationkind) has 0-Public 1-protected 2-Private 3-default. These are the inheritance attributes corresponding to C ++.

Here, we will try protection inheritance.

Then generate the C ++ code to see the effect:

There is no problem with the selection of the inherited code.

Or that sentence,Everything is so beautiful, haha.
