29 | // The visitor type should specify the previsit/postvisit/premutate/postmutate for types that are desired. |
---|
30 | // Note: previsit/postvisit/premutate/postmutate must be **public** members |
---|
31 | // |
---|
32 | // Several additional features are available through inheritance |
---|
33 | // | WithTypeSubstitution - provides polymorphic TypeSubstitution * env for the current expression |
---|
34 | // | WithStmtsToAdd - provides the ability to insert statements before or after the current statement by adding new statements into |
---|
35 | // stmtsToAddBefore or stmtsToAddAfter respectively. |
---|
36 | // | WithShortCircuiting - provides the ability to skip visiting child nodes; set visit_children to false in pre{visit,mutate} to skip visiting children |
---|
37 | // | WithGuards - provides the ability to save/restore data like a LIFO stack; to save, call GuardValue with the variable to save, the variable |
---|
38 | // will automatically be restored to its previous value after the corresponding postvisit/postmutate teminates. |
