Double getters

[Krice]

I'm wondering is there a way to avoid having "double" getters:

class A
{
Compo *_C;
public:
int Get_From_C();
....

int A::Get_From_C() { return _C->Get_Something(); }

This problem gets worse if A is derived from a base
class and only some derived classes have Compo class.
Then you need to write a virtual getter if some routine
requires the base handle.

First identifiers starting with an underscore and a capital letter are
reserved for the implementation. Change _C to _c or c_ or something
else.
public:
int Get_From_C();
...

int A::Get_From_C() { return _C->Get_Something(); }

That's just the price of encapsulation (see

though you might improve things by refactoring your design. Compare
