I am looking for a way to obtain the class hierarchy of a program in
MacPas mode (where there are no published properties). TObject has
ClassParent, so a list of Class types would be sufficient, I think. I
can't find however a routine in the RTL to obtain such a list.
There is no such routine in the RTL, to my knowledge.
Can I add it ? I guess a low-level pointer to a list of VMT's would be
sufficient to implement it ?
Problem is: it breaks smartlinking.
Yes, I understand that. I looked at the assembly generated for a simple test program and there are
separate al_globals entries for each vmt and separate al_rtti entries for the vmt rtti. I asssume
the very reason for the separate entries is smart linking.
Hm, I guess I can look at the data section of the executable but it would be highly dependant of
the executable binary format.
Is it possible to produce a separate data section/entry that refers to all al_globals and/or all
al_rtti entries without breaking smart-linking ?
Why? It's just walking the ParentClass hierarchy of a given class; which is
what RTTI does anyway ?
And the other way round (from a class to each subclass).
