Extract superclass

Examples

class SomeClass {
    char SomeChar = 'a';
    long d22;

    //This function will be extracted to a base class
    void exFunc(int);
};

class SuperClass {
    void exFunc(int);
};

class SomeClass : public SuperClass {
    char SomeChar = 'a';
    long d22;
};

Extracting the class dependent members

Let's consider the following sample of code:

int d1;
class XClass {
    static const int d2 = 13;
    int exRes = d2 * d1;
};

As you can see, there is a dependency between d1 and exRes. If you apply Extract Superclass refactoring to the above class and try to select exRes to be moved, CLion highlights the d2 variable with blue:

Trying to proceed with extract, you will get the following warning message:

Choose Continue to ignore the problem and proceed with refactoring, or Cancel to return back and resolve it. Also you can observe the conflict in Find Tool Window.
