Detailed Description
Implements FUnknown and IDependent.
FObject is a polymorphic class that implements IDependent (of SKI module) and therefore derived from FUnknown, which is the most abstract base class of all.
All COM-like virtual methods of FUnknown such as queryInterface(), addRef(), release() are implemented here. On top of that, dependency-related methods are implemented too.
Pointer casting is done via the template methods FCast, either FObject to FObject or FUnknown to FObject.
FObject supports a new singleton concept, therefore these objects are deleted automatically upon program termination.
- Runtime type information: An object can be queried at runtime, of what class it is. To do this correctly, every class must override some methods. This is simplified by using the OBJ_METHODS macros
