TClassRef Class Reference

TClassRef is used to implement a permanent reference to a TClass object.

In particular this reference will change if and when the TClass object is regenerated. This regeneration usually happens when a library containing the described class is loaded after a file containing an instance of this class has been opened.

The references kept track of using an intrusive double linked list. The intrusive list is maintained by TClass::AddRef and TClass::RemoveRef. The 'start' of the list is held in TClass::fRefStart.
