Hi,
I have the following hierarchy of classes
class classOne
{
virtual void abstractMethod() = 0;
};
class classTwo : public classOne
{
};
class classThree : public classTwo
{
};
All classOne, classTwo and classThree are abstract classes, and I have another class that is defining the pure virtual methods
class classNonAbstract : public classThree
{
void abstractMethod();
// Couple of new methods
void doIt();
void doItToo();
};
And right now I need it differently...I need it like
class classNonAbstractOne : public classOne
{
void abstractMethod();
// Couple of new methods
void doIt();
void doItToo();
};
class classNonAbstractTwo : public classTwo
{
void abstractMethod();
// Couple of new methods
void doIt();
void doItToo();
};
and
class classNonAbstractThree : public classThree
{
void abstractMethod();
// Couple of new methods
void doIt();
void doItToo();
};
But all the nonAbstract classes have the same new methods, with the same code...and I would like to avoid copying all the methods and it's code to every nonAbstract class. How could I accomplish that?
Hopefully it's understandable...
