Your structure requires that the base class has knowledge of all classes that inherit from it (and possibly, its deepest descendants <-- though I doubt it).

The way around this is to have subclasses register with their parent class. Then, the parent consults a registry before instantiation a class, rather than hard-coding knowledge of the class hierarchy.
