Visit Declaration related nodes. | |
Visiting declarations is simple, but there are many clauses. This is because in Tiger, the declarations are processed by chunks (a chunk of Function declarations, then Var or Type, then ...). So we have to explain
| |
virtual void | operator() (typename Const< DecsList >::type &e) override |
Visit a list of function, type and/or variables declarations. | |
virtual void | operator() (typename Const< Decs >::type &e) |
Visit a Decs chunks. | |
virtual void | operator() (typename Const< VarDecs >::type &e) override |
Visit Var declarations. | |
virtual void | operator() (typename Const< VarDec >::type &e) override |
virtual void | operator() (typename Const< FunctionDec >::type &e) override |
virtual void | operator() (typename Const< TypeDec >::type &e) override |
template<typename DecsType > | |
void | decs_visit (typename Const< DecsType >::type &e) |
Visit a chunk (i.e., a list of Function, Var, and Type decs). | |
Visit Type related nodes. | |
virtual void | operator() (typename Const< NameTy >::type &e) override |
virtual void | operator() (typename Const< RecordTy >::type &e) override |
virtual void | operator() (typename Const< ArrayTy >::type &e) override |
Visit Field related nodes. | |
virtual void | operator() (typename Const< Field >::type &e) override |
Object-related visits. | |
The methods should not be used, since this visitor is for the non-object flavor of the language. | |

A convenient shortcut for recurring code like this:
However, the drawback of this approach is that it doesn't take care of the constness, and any const violation will be reported within the body of this method, not at its corresponding call site.
We cannot use the misc/select_const.hh approach here, since the compiler cannot resolve a function overloaded or specialized on an associated type of a template. E.g., writing accept like this:
won't work directly. Of course, one can help the compiler, providing it with E
but this is painful.

inlineinherited |
Visit a chunk (i.e., a list of Function, Var, and Type decs).
It is exactly the same in the three cases, so the code is factored via a template method.
