42 | // Templated visitor type |
---|
43 | // To use declare a Pass< YOUR VISITOR TYPE > |
---|
44 | // The visitor type should specify the previsit/postvisit for types that are desired. |
---|
45 | // Note: previsit/postvisit must be **public** members |
---|
46 | // |
---|
47 | // Several additional features are available through inheritance |
---|
48 | // | PureVisitor - makes the visitor pure, it never modifies nodes in place and always |
---|
49 | // clones nodes it needs to make changes to |
---|
50 | // | WithConstTypeSubstitution - provides polymorphic const TypeSubstitution * typeSubs for the |
---|
51 | // current expression |
---|
52 | // | WithStmtsToAdd - provides the ability to insert statements before or after the current |
---|
53 | // statement by adding new statements into stmtsToAddBefore or |
---|
54 | // stmtsToAddAfter respectively. |
---|
55 | // | WithDeclsToAdd - provides the ability to insert declarations before or after the |
---|
56 | // current declarations by adding new DeclStmt into declsToAddBefore or |
---|
57 | // declsToAddAfter respectively. |
---|
58 | // | WithShortCircuiting - provides the ability to skip visiting child nodes; set visit_children |
---|
59 | // to false in pre{visit,visit} to skip visiting children |
---|
60 | // | WithGuards - provides the ability to save/restore data like a LIFO stack; to save, |
---|
61 | // call GuardValue with the variable to save, the variable will |
---|
62 | // automatically be restored to its previous value after the |
---|
63 | // corresponding postvisit/postmutate teminates. |
---|
64 | // | WithVisitorRef - provides an pointer to the templated visitor wrapper |
---|
65 | // | WithSymbolTable - provides symbol table functionality |
---|
66 | // |
---|
67 | // Other Special Members: |
---|
68 | // | beginScope - A method with no parameters or return value, called each time the |
---|
69 | // visitor enters a block. |
---|
70 | // | endScope - A method with no parameters or return value, called each time the |
---|
71 | // visitor leaves a block. |
---|
72 | // | result - Either a method that takes no parameters or a field. If a method (or |
---|
73 | // callable field) get_result calls it, otherwise the value is returned. |
