[c++] Virtualne funkcije

Živjo,

malo sem spremenil code convention in bi rad imel v razredih "get" in "set" metode brez
predpon get in set... npr.:

class NamestoTega
{
   void setCharset(const std::string& charset);
   const std::string& getCharset() const; 
};

class BiImelTole
{
   void charset(const std::string& charset);
   const std::string& charset() const; 
};

Napaka pa se pojavi pri dedovanju... npr.:

#include <iostream>

class Base
{
    public:
        virtual void charset(const std::string& charset)
        {
            m_charset = charset;
        }

        virtual const std::string& charset() const
        {
            return m_charset;
        }

    private:
        std::string m_charset;
};

class Derived : public Base
{
    public:
       virtual void charset(const std::string& charset)
       {
           Base::charset(charset);
       }
};

int main()
{
    Derived d;
    d.charset("Bla");
    std::cout << d.charset() << std::endl;
    return 0;
}

Napaka:

/data/temp/test/main.cpp||In function 'int main()':|
/data/temp/test/main.cpp|35|error: no matching function for call to 'Derived::charset()'|
/data/temp/test/main.cpp|24|note: candidates are: virtual void Derived::charset(const std::string&)|
||=== Build finished: 1 errors, 0 warnings ===|

Ali na tak način ne gre??? V Derived classu izgleda da overridana "set" metoda "povozi" še
dedovani getter iz Base classa?

PS: Naslov teme je malo trapast ampak se nisem mogel spomniti nič boljšega

aha super bom poskusil...
Hvala
