Static Class Members
suggest changeStatic members have class scope as opposed to object scope
C++ Example
// define in header
class Singleton {
public:
static Singleton *getInstance();
private:
Singleton() {}
static Singleton *instance;
};
// initialize in .cpp
Singleton* Singleton::instance = 0;
Java Example
public class Singleton {
private static Singleton instance;
private Singleton() {}
public static Singleton getInstance() {
if(instance == null) {
instance = new Singleton();
}
return instance;
}
}
Found a mistake? Have a question or improvement idea?
Let me know.
