The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Unsure of how to best implement this relationship.

Asked by Unimatrix_001 in Theory, Software/Systems Design, Design Patterns

Hello,

I have the following code - please excuse the C++ syntax, although what there is I'm sure is simple enough for all to understand. Although essentially I have two classes, one containing a simple variable, with a set and get method. The other class is what would do the work on the first class (in this case we simply set the variable to true).

However, my issue is in the main method, at the point of interest I should not be able to call the set method of CMyClass - that method should only be available to the CWorkerClass (and possibly a couple of others); I should only be able to call the get method.

My question is, how can I design such a thing that would allow this?

Thanks,
Uni
