Why is this an issue?
In the interest of code clarity, static member variables of a base class should never be accessed using a derived type’s name. Doing
so is confusing and could create the illusion that two different static variables exist. If the variable is const, there is no risk of
confusion.
Noncompliant code example
class Parent {
public:
static int count;
static Color const defaultColor = green;
};
class Child : public Parent {
public:
Child() : myColor(Child::defaultColor) // Compliant, this is a constant
{
Child::count++; // Noncompliant
}
};
Compliant solution
class Parent {
public:
static int count;
static Color const defaultColor = green;
};
class Child : public Parent {
public:
Child() : myColor(Child::defaultColor) // Compliant, this is a constant
{
Parent::count++;
}
};
