Question

I’ve been spoiled using Java in the last few months! I have a C++ project where I would like to decouple a class interface (.h file) from its implementation details. But the class’s member fields have to be in its declaration, and it seems like I have this unavoidable dependency linking if I want to tweak the class’s member fields.

I know one way to do this is using polymorphism + class inheritance (make the interface a base class, make the implementation a derived class), but if I remember right, that requires virtual functions, which are something I would like to avoid — this is on a DSP and it’s advantageous not to get too “C++-y” with things.

any suggestions?

Answer 1

You want the PIMPL idiom.
