You say nothing about the way[s] those "concepts" or enums
are going
to be used.
You have to read the whole post, this is already listed
below:
In the specific case I am creating a greatly simplified C++
interpreter and the subset concepts are data types and the
superset
concepts are SymbolTable types, the SymbolTable has some of
its own
specialized types such as Function ProtoType.
<sigh> Why do you presume I didn't read the post? How do you design
your classes? Do you pick a language element, like "a virtual function"
and build your program around it? Like here, you just say, "Today I'll
use enums, they go nicely with a switch statement". Is that all? No
interface? No messaging? No states?
Why do you have classes? Take SymbolTable class, why does it need those
enums? Are you implementing some kind of dispatch mechanism with those?
Why not with indices or function pointers? Does the "simplified" in
your description of what you're programming relate to "C++" or to
"interpreter"?
The enums will be used in switch statements.
Well, duh.
There are other things that can be use in switch statements, you know,
like characters or other integral values. Dispatch can also be done
using virtual functions and pointers to member functions... Arrays
(vectors) are much easier to append to each other than enums...
