c++ - Which is best for a repeating piece of code? -

-

I have a class with two member functions that share a part of the code: 

 
 Code> Zero A :: first () {first function epilog (); SharedPart (); } Zero A: second () {secondfunction epigl (); SharedPart (); }

Currently First Function Epilog () , secondFunctionEpilogue () and Shared Part () calls But not just code fragments, shared part () code is being repeated. I want to get rid of duplication.

The shared piece of code does not require access to any member of the class. Therefore, I can apply it in any of three ways:

  • A stable member function,
  • a CONST non-static member function or
    • < Li> A Local Function

Which version is better and why?

If your function reaches the state but it does not change, then use the consonant member function.

Your case:

If this does not require your function 1) access to any member of the code, and 2) that belongs to that class , Then make it a stable work of your class.

In this way it is clear that it is not modifying the state nor the position of the object.

An additional case you have not mentioned:

There is one more thing that you can do too. And that is, your Shaidepart takes a member function pointer and calls it and then processes its main body. If you have first (), second (), third (), fourth (), ... such functions, then there may be less code duplication, thus you do not need to share SharePart (); At the end of each member function, and you can reuse the first (), seconds (), third () ... without calling the sharedpart () code.

c++ - Linux and clipboard -

After selecting the copies of the buffer in Linux, after the text, we can click and paste the button between the mouse. I think there is a special buffer for this, I want to use it. Programming Language: C ++ Your Library: Qt Thanks. There is just one more correct answer than Paul Dixon, which answers your needs: / P > QClipboard * clipboard = QApplication :: clipboard (); CastString Selected Text = Clipboard-> Text (QClipboard :: Selection);

What is expire header and how to achive them in ASP.NET and PHP? -

I have examined the performance statistics of my website today. I have received a warning (or error may occur) that is given below Add Terminal Headers Here are 15 static components without a 15-futures end date * (no end) Http://www.example.com/video/css/global.css * (no time limit) http://www.example.com/video/js/global.js * (no expiration ) Http: //www.example.com/video/images/main-bg.png what it means and how to achieve it both in PHP and ASP.Net. I am on a shared hosting server, so please tell me some ways to use the code, because I can not make any modifications at the end of the server. If I expire the header, then there is no chance that if I make changes to the CSS, then the user will not be able to remove them immediately because CSS and other files have a fixed time limit (1 month, week ) Are cached for. Is Is there any harm to using PHP? $ time = time () + 3 * 24 * 60 * 60; // 3 day headings ('End:'. GMDAT ('D, D MYH: i: s \ g \ m \ t',

sql server - How can I determine which of my SQL 2005 statistics are unused? -

-
After a few years, one of my biggest databases has deposited 73 figures out of its largest tables. With Indexes, I can run many types of reports and queries, how often / heavily specific indexes are used. What is an equivalent for data? We are running SQL 2005. To make statistics automatically managed and honest, I would like to "update statistics", "create statistics" and There is no information about any management except "drop statistics" orders. In theory, UPDATE should handle the addition and removal of statistical data. In addition, I've never heard about the amount of storage or storage taking in large amounts, so I'm not sure whether there is any reason for the alarm or not. If you are seeing a potential problem, then I would suggest running an update before, if it does not clean it, it is leaving and then it appears to be safe operation (because it is the only query optimizer Is for). I will not leave "left" in the
