Is it possible to avoid repeating the class name in the implementation file?

Question

Is there a way to avoid the Graph:: repetition in the implementation file, yet still split the class into header + implementation? Such as in:

Header Fi

Answer 1

        //yes it is possible using preprocessor like this:

        #define $ ClassName //in .cpp 

    void $::Method1() 
    { 
    } 

    //or like this: in the header .h:

        #undef $
        #define $ ClassName' 

// but you have to include the class header in last #include in your .cpp:

        #include "truc.h"
        #include "bidule.h" ...
        #include "classname.h" 

        void $::Method() { }  

        //i was using also 
        #define $$ BaseClass 
        //with single inheritance  than i can do this: 

        void $::Method() 
        { 
        $$::Method(); //call base class method 
        } 

        //but with a typedef defined into class like this it's better to do this: 
        class Derived : Base 
        { 
        typedef Base $$;  

    }
