[Qt] QScriptValuePrivate class needs some cleanup.

• Component: JavaScriptCore
• Status: RESOLVED FIXED

[Jędrzej Nowacki]

QtScript implementation is placed in a private classes. Private classes should use only other private classes to avoid unnecessary conversions. QScriptValuePrivate breaks this rule, which is wrong. QScriptValuePrivate constructor shouldn't take QScriptEngine pointer as a parameter.

No need to say it is wrong, you already made that clear. Remove dedundant information.

Is this another comment? or are you fixing a second thing?

I do not understand this get method? It gets the private of the engine? I guess you use a kind of smart pointer inside it, couldn't the method to the data() internally in that method. The code is not easy readable.

Yes and the class do not have to be a friend, In general the get method is used for conversion between a public and a private class. In QtScript I decided to separete a public implementation and a private implementation. Public implementation is used only for converting to a private one. All real work is done in a private implementation. The design adventage is that we can inline nearby all methods in private imlementation and we do not waste time for converting values inside private implementation. If you want I can describe it in detail.

You are right. It is done.
