virtual void FinishObject ( )

inlinevirtual

Allows the object the opportunity to configure itself after having all its children initialized and properties set by the code generator. By default, users do not need to call this function, it is called by the generated code in CreateObjects() if the object is a user defined class. User defined classes can override this, calling BaseClass::FinishObject(), before supplying class specific initialization code as needed. User code should only conisder itself and its children as the hierarchy above will not have been set up yet. User code should not call FinishObject on its children, since it will have already been called when those children were created. This method will be called by generated code once this object and its children have been fully instantiated.
