- C++ Pure Virtual Functions 7:00 PM 9/10/90
-
- By using pure virtual functions in C++ [Lippman, p. 340], one can
- specify that a class is not to be instantiated, but must serve as the
- base class for one or more derivations. Does the MPW C++ compiler
- still generate virtual tables for the base class, or is it smart
- enough to suppress the tables knowing that they will never be
- needed?
-
- If C++ emits the virtual tables, will the linker be smart enough
- to strip them away since there can never be data references to them?
