Detailed Description

template<template< typename > class Const>
class ast::GenObjectVisitor< Const >

GenObjectVisitor<CONSTNESS-SELECTOR> provides default visit methods for object-related nodes. This class is meant to factor the code visiting object-related nodes.

ast::GenObjectVisitor inherits virtually from ast::GenVisitor to allow diamond inheritance, notably for a ``compatibility'' purpose with ast::GenDefaultVisitor.

For instance, bind::Binder, a visitor that handles bindings for an AST without objects, inherits from ast::DefaultVisitor to factor default (``empty'') traversal implementations for non-object-related nodes, and from ast::ObjectVisitor for object-related nodes.

Member Function Documentation

template<template< typename > class Const>
template<typename E >
void ast::GenVisitor< Const >::accept ( E *  e)
protectedinherited

A convenient shortcut for recurring code like this:

if (e)
e->accept(*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:

template <typename E>
void accept(typename Const<E>::type* e);

won't work directly. Of course, one can help the compiler, providing it with E

accept<ast::NameTy>(e.result_get());

but this is painful.
