boost signals

I'm sure you know them already, but your example would be even cleaner and easier with boost signals. The entire CallbackHandler would be unnessesary:

class ClassWithCallbacks
{
public:
	void registerSelf(boost::signal<void ()> & callbackHandler)
	{
		callbackHandler.connect(boost::bind(&ClassWithCallbacks::callback1, this));
		callbackHandler.connect(boost::bind(&ClassWithCallbacks::callback2, this));
	}
private:
	void callback1() { /* bla */ }
	void callback2() { /* more bla */ }
};

usage:

boost::signal<void ()> sig;
ClassWithCallbacks justAClass;
justAClass.registerSelf(sig);
 
//do Callbacks:
sig();

BTW, I think there's a typo in your Listing's: Shouldn't it be

private:
  void callback1() { /* dosomething */ }
  void callback2() { /* dosomething */ }

instead of
private:
  void callback1Impl() { /* dosomething */ }
  void callback2Impl() { /* dosomething */ }
